Instructions When Handling Refrigerant 1.

R-134a liquid refrigerant is highly volatile. A drop on the skin of your hand could result in localized frostbite. When handling the refrigerant, be sure to wear gloves.

2.

It is standard practice to wear goggles or glasses to protect your eyes, and gloves to protect your hands. If the refrigerant splashes into your eyes, wash them with clean water immediately.

3.

The R-134a container is highly pressurized. Never leave it in a hot place, and check that the storage temperature is below 52°C (126°F)

4.

An electronic leak detector should be used to check the system for refrigerant leakage. Bear in mind that the R-134a, upon coming into contact with flame, produces phosgene, a highly toxic gas.

5.

Use only recommended the lubricant for R-134a systems. If lubricants other than the recommended one used, system failure may occur.

6.

PAG lubricant absorbs moisture from the atmosphere at a rapid rate, therefore the following precautions must be observed: A. When removing refrigerant components from a vehicle, cap immediately the components to prevent from the entry of moisture. B. When installing refrigerant components to a vehicle, do not remove the cap until just before connecting the components. C. Complete the connection of all refrigerant tubes and hoses without delay to prevent the A/C system from taking on moisture. D. Use the recommended lubricant from a sealed container only.

7.

If an accidental discharge in the system occurs, ventilate the work area before resuming service.

When Replacing Parts On A/C System 1.

Never open or loosen a connection before discharging the system.

2.

Seal the open fittings of components with a cap or plug immediately to prevent intrusion of moisture or dust.

3.

Do not remove the sealing caps from a replacement component until it is ready to be installed.

4.

Before connecting an open fitting, always install a new sealing ring. Coat the fitting and seal with refrigerant oil before making the connection.

General Page 25

When Installing Connecting Parts Flange With Guide Pin Check the new O-ring for damage (use only the specified) and lubricate it using compressor oil. Tighten the nut to specified torque.

Handling Tubing And Fittings The internal parts of the refrigeration system will remain in a state of chemical stability as long as pure moisture-free refrigerant and refrigerant oil are used. Abnormal amounts of dirt, moisture or air can upset the chemical stability and cause problems or serious damage.

The Following Precautions Must Be Observed General Page 26

The Following Precautions Must Be Observed 1.

When it is necessary to open the refrigeration system, have everything you will need to service the system ready so the system will not be left open any longer than necessary.

2.

Cap or plug all lines and fittings as soon as they are opened to prevent the entrance of dirt and moisture.

3.

All lines and components in parts stock should be capped or sealed until they are ready to be used.

4.

Never attempt to rebind formed lines to fit. Use the correct line for the installation you are servicing.

5.

All tools, including the refrigerant dispensing manifold, the gauge set manifold and test hoses, should be kept clean and dry.

Refrigerant System Service Basics Refrigerant Recovery Use only service equipment that is U.L-listed and is certified to meet the requirements of SAE J2210 to remove HFC-134a(R-134a) from the air conditioning system.

- Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat. - Be careful when connecting service equipment. - Do not breathe refrigerant or vapor. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers. 1.

Connect an R-134a refrigerant Recovery/Recycling/Charging System (A) to the high-pressure service port (B) and the lowpressure service port (C) as shown, following the equipment manufacturer's instructions.

General Page 29

2.

Measure the amount of refrigerant oil removed from the A/C system after the recovery process is completed. Be sure to install the same amount of new refrigerant oil back into the A/C system before charging.

System Evacuation Use only service equipment that is U.L-listed and is certified to meet the requirements of SAE J2210 to remove HFC-134a(R-134a) from the air conditioning system.

- Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat. - Be careful when connecting service equipment. - Do not breathe refrigerant or vapor. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers. 1.

When an A/C System has been opened to the atmosphere, such as during installation or repair, it must be evacuated using an R-134a refrigerant Recovery/Recycling/Charging System. (If the system has been open for several days, the receiver/dryer should be replaced, and the system should be evacuated for several hours.)

2.

Connect an R-134a refrigerant Recovery/Recycling/Charging System (A) to the high-pressure service port (B) and the low-pressure service port (C) as shown, following the equipment manufacturer's instructions.

3.

If the low-pressure does not reach more than 93.3 kPa (700 mmHg, 27.6 in.Hg) in 10 minutes, there is probably a leak in the system. Partially charge the system, and check for leaks (see Leak Test.).

4.

Remove the low pressure valve from the low-pressure service port.

System Charging Use only service equipment that is U.L-listed and is certified to meet the requirements of SAE J2210 to remove HFC-134a(R-134a) from the air conditioning system.

- Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat. - Be careful when connecting service equipment.

General Page 30

- Do not breathe refrigerant or vapor. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers. 1.

Connect an R-134a refrigerant Recovery/Recycling/Charging System (A) to the high-pressure service port (B) as shown, following the equipment manufacturer's instructions.

2.

Add the same amount of new refrigerant oil to system that was removed during recovery. Use only specified refrigerant oil. Charge the system with 17.6 ± 0.88 (450 ± 25) of R-134a refrigerant. Do not overcharge the system the compressor will be damaged.

Refrigerant Leak Test Always conduct a leak test with an electronic leak detector whenever leakage or refrigerant is suspected and when conducting service operations which are accompanied by disassembly or loosening or connection fittings. In order to use the leak detector properly, read the manual supplied by the manufacturer. If a gas leak is detected, proceed as follows: 1.

Check the torque on the connection fittings and, if too loose, tighten to the proper torque. Check for gas leakage with a leak detector (A).

2.

If leakage continues even after the fitting has been tightened, discharge the refrigerant from the system, disconnect the fittings, and check their seating faces for damage. Always replace, even if the damage is slight.

3.

Check the compressor oil and add oil if required.

4.

Charge the system and recheck for gas leaks. If no leaks are found, evacuate and charge the system again.

2011 > G 1.1 SOHC > Restraint

General Information The supplemental restraint system (SRS) is designed to supplement the seat belt to help reduce the risk or severity of injury to the driver and passenger by activating and deploying the driver, passenger, side airbag and belt pretensioner in certain frontal or side collisions. The SRS (Airbag) consists of : a driver side airbag module located in the center of the steering wheel, which contains the folded cushion and an inflator unit ; a passenger side airbag module located in the passenger side crash pad contains the folded cushion assembled with inflator unit ; side airbag modules located in the driver and passenger seat contain the folded cushion and an inflator unit. The impact sensing function of the SRSCM is carried out by electronic accelerometer that continuously measure the vehicle's acceleration and delivers a corresponding signal through amplifying and filtering circuitry to the microprocessor.

SRSCM (SRS Control Module) SRSCM will detect front impact with front impact sensor, and side impact with side impact sensor, and determine airbag module deployment. 1.

DC/DC converter: DC/DC converter in power supply unit includes up/down transformer converter, and provide ignition voltage for 2 front airbag ignition circuits and the internal operation voltage of the SRSCM. If the internal operation voltage is below critical value setting, it will perform resetting.

2.

Back up power supply: SRSCM has separate back up power supply, that will supply deployment energy instantly in low voltage condition or upon power failure by front crash.

3.

Self diagnosis: SRSCM will constantly monitor current SRS operation status and detect system failure while vehicle power supply is on, system failure may be checked with trouble codes using GDS.

4.

Airbag warning lamp on: Upon detecting error, the module will transmit signal to SRSCM indicator lamp located at cluster. MIL lamp will indicate driver SRS error. Upon ignition key on, SRS lamp will turn on for about six seconds.

5.

Trouble code registration: Upon error occurrence in system, SRSCM will store DTC corresponding to the error. DTC can be cleared only by GDS. However, if an internal fault code is logged or if a crash is recorded thefault clearing should not happen.

6.

Self diagnostic connector: Data stored in SRSCM memory will be output to GDS or other external output devices through connector located below driver side crash pad.

7.

Once airbag is deployed, SRSCM should not be used again but replaced.

8.

Side airbag deployment will be determined by SRSCM that will detect satellite sensor impact signal upon side crash, irrespective to seat belt condition.

Precautions General Precautions Please read the following precautions carefully before performing the airbag system service. Observe the instructions described in this manual, or the airbags could accidentally deploy and cause damage or injuries. • Except when performing electrical inspections, always turn the ignition switch OFF and disconnect the negative cable from the battery, and wait at least three minutes before beginning work. The contents in the memory is not erased even if the ignition switch is turned OFF or the battery cables are disconnected from the battery. • Use the replacement parts which are manufactured to the same standards as the original parts and quality. Do not install used SRS parts from another vehicle. Use only new parts when making SRS repairs. • Carefully inspect any SRS part before you install it. Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.

• Before removing any of the SRS parts (including the disconnection of the connectors), always disconnect the SRS connector.

Airbag Handling and Storage Do not disassemble the airbags; it has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused. For temporary storage of the air bag during service, please observe the following precautions. • Store the removed airbag with the pad surface up. • Keep free from any oil, grease, detergent, or water to prevent damage to the airbag assembly.

Restraint Page 3

• Store the removed airbag on secure, flat surface away from any high heat source (exceeding 85° C/185°F). • Never perform electrical inspections to the airbags, such as measuring resistance. • Do not position yourself in front of the airbag assembly during removal, inspection, or replacement. • Refer to the scrapping procedures for disposal of the damaged airbag. • Be careful not to bump or impact the SRS unit or the side impact sensors whenever the ignition switch is ON, wait at least three minutes after the ignition switch is turned OFF before begin work. • During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit and the side impact sensor. The airbags could accidentally deploy and cause damage or injury. • After a collision in which the airbags were deployed, replace the front airbags and the SRS unit. After a collision in which the side airbag was deployed, replace the side airbag, the front impact sensor and side impact sensor on the side where the side airbag deployed and the SRS unit. After a collision in which the airbags or the side air bags did not deploy, inspect for any damage or any deformation on the SRS unit and the side impact sensors. If there is any damage, replace the SRS unit, the front impact sensor and/or the side impact sensors. • Do not disassemble the SRS unit, the front impact sensor or the side impact sensors • Turn the ignition switch OFF, disconnect the battery negative cable and wait at least three minutes before beginning installation or replacement of the SRS unit. • Be sure the SRS unit, the front impact sensor and side impact sensors are installed securely with the mounting bolts. • Do not spill water or oil on the SRS unit,or the front impact sensor or the side impact sensors and keep them away from dust. • Store the SRS unit, the front impact sensor and the side impact sensors in a cool (15 ~ 25°C/59 ~ 77°F) and dry (30% ~ 80% relative humidity, no moisture) area.

Wiring Precautions SRS wiring can be identified by special yellow outer covering. Observe the instructions described in this section. • Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage in SRS wiring, replace the harness.

Restraint Page 4

• Be sure to install the harness wires so that they are not pinched, or interfere with other parts.

• Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-metal contact. Poor grounding can cause intermittent problems that are difficult to diagnose.

Precautions for Electrical Inspections • When using electrical test equipment, insert the probe of the tester into the wire side of the connector. Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector.

• Use a u-shaped probe. Do not insert the probe forcibly. • Use specificed service connectors for troubleshooting. Using improper tools could cause an error in inspection due to poor metal contact.

Warning Lamp Activation Warning Lamp Behavior After Ignition On As soon as the operating voltage is applied to the SRSCM ignition input, the SRSCM activates the warning lamp for a bulb check. The lamp shall turn on for 6 seconds during the initialization phase and be turned off afterward. However, in order to indicate the driver, the warning lamp shall turn on for 6 seconds and off for one second then on continuously after the operating voltage is applied if any active fault exists. 1.

Active fault or historical fault counter is greater or equal to 10

2.

Normal or historical fault counter is less than 10

SRSCM Independent Warning Lamp Activation There are certain fault conditions in which the SRSCM cannot function and thus cannot control the operation of the standard warning lamp. In these cases, the standard warning lamp is directly activated by appropriate circuitry that operates independently of the SRSCM. These cases are: 1.

Loss of battery supply to the SRSCM : warning lamp turned on continuously.

2.

Loss of internal operating voltage : warning lamp turned on continuously.

3.

Loss of Microprocessor operation : warning lamp turned on continuously.

4.

SRSCM not connected : warning lamp turned on continuously through the shorting bar.

Passenger Airbag Deactivation (PAD) Lamp Operation The SRSCM is designed with circuitry and software to drive a PAD lamp, which is used for depowered airbag system. For the PAD indicator circuitry to function properly, both the SRSCM and PAD indicator are sourced from the same ignition line. After ignition on, the PAD indicator will be turned on for 4 seconds and off for 3 seconds during the initialization phase. Thereafter the lamp will be turned on as long as the PAD switch is in the disabled position.

Description The primary purpose of the SRSCM (Supplemental Restraints System Control Module) is to discriminate between an event that warrants restraint system deployment and an event that does not. The SRSCM must decide whether to deploy the restrain system or not. After determining that pretensioners and/or airbag deployment is required, the SRSCM must supply sufficient power to the pretensioners and airbag igniters to initiate deployment. The SRSCM determines that an impact may require deployment of the pretensioners and airbags from data obtained from impact sensors and other components in conjunction with a safing function. The SRSCM will not be ready to detect a crash or to activate the restraint system devices until the signals in the SRSCM circuitry stabilize. It is possible that the SRSCM could activate the safety restraint devices in approximately 2 seconds but is guaranteed to fully function after prove-out is completed. The SRSCM must perform a diagnostic routine and light a system readiness indicator at key-on. The system must perform a continuous diagnostic routine and provide fault annunciation through a warning lamp indicator in the event of fault detection. A serial diagnostic communication interface will be used to facilitate servicing of the restraint control system.

Operation and Leakage Check Check all of the following items: Component

Procedure

Brake Booster (A)

Check brake operation by applying the brakes during a test drive. If the brakes do not work properly, check the brake booster. Replace the brake booster as an assembly if it does not work properly or if there are signs of leakage.

Piston cup and pressure cup inspection (B)

Check brake operation by applying the brakes. Look for damage or signs of fluid leakage. Replace the master cylinder as an assembly if the pedal does not work properly or if there is damage or signs of fluid leakage. Check for a difference in brake pedal stroke between quick and slow brake applications. Replace the master cylinder if there is a difference in pedal stroke

Brake hoses (C )

Look for damage or signs of fluid leakage. Replace the brake hose with a new one if it is damaged or leaking.

Caliper piston seal Check brake operation by applying the brakes. and piston boots Look for damage or signs of fluid leakage. If the pedal does not work properly, the (D) brakes drag, or there is damage or signs of fluid leakage, disassemble and inspect the brake caliper. Replace the boots and seals with new ones whenever the brake caliper is disassembled.

Brake Booster Operating Test For simple checking of the brake booster operation, carry out the following tests : 1.

Run the engine for one or two minutes, and then stop it. If the pedal depresses fully the first time but gradually becomes higher when depressed succeeding times, the booster is operating properly, if the pedal height remains unchanged, the booster is defective.

Brake System Page 8

2.

With the engine stopped, step on the brake pedal several times. Then step on the brake pedal and start the engine. If the pedal moves downward slightly, the booster is in good condition. If there is no change, the booster is defective.

3.

With the engine running, step on the brake pedal and then stop the engine. Hold the pedal depressed for 30 seconds. If the pedal height does not change, the booster is in good condition, if the pedal rises, the booster is defective. If the above three tests are okay, the booster performance can be determined as good. Even if one of the above three tests is not okay, check the check valve, vacuum hose and booster for defect.

Vacuum Hose (Check Valve) Inspection 1.

Disconnect the brake booster vacuum hose (check valve built in) (A) at the booster .

2.

Start the engine and let it idle. There should be vacuum available. If no vacuum is available, the check valve is not working properly. Replace the brake booster vacuum hose and check valve and retest.

Brake System Page 9

Brake Pedal & Brake Switch Adjustment Pedal Height 1.

Disconnect the brake switch connector, loosen the brake switch locknut (A), and brake off the brake switch (B) until it is no longer touching the brake pedal.

2.

Measure the pedal height (C) from the middle of the left-side center of the pedal pad. Standard pedal height (on the carpet) : 205 mm (8.07 in)

3.

Loosen the pushrod locknut (A), and screw the pushrod in or out with pliers until the standard pedal height from the floor is reached. After adjustment, tighten the locknut firmly. Do not adjust the pedal height with the pushrod depressed.

Stop Lamp Switch Clearance Screw in the stop lamp switch until its switch rod is fully depressed (threded end (A) touching the pad (B) on the pedal arm) then brake off the switch 3/4 turn to make 1.0~2.0 mm(0.04~0.08 in.) of clearance between the stop lamp switch pad. Make sure that the brake lights go off when the pedal is released.

Brake System Page 10

Pedal Free Play 1.

With the engine stopped, depress the brake pedal two or three times. After eliminating the vacuum in the power brake booster, press the pedal(B) down by hand, and confirm that the amount of movement(A) before resistance is met (the free play) is within the standard value. Standard value : 3 ~ 8 mm (0.117 - 0.312 in.)

2.

If free play does not reach the standard value, check that clearance between the outer case of stop lamp switch(C) and brake pedal is within the standard value. If free play exceeds the standard value, it is probably due to excessive clearance between the clevis pin and brake pedal arm. Check for excessive clearance and replace faulty parts as required.

3.

Start the engine, depress the brake pedal with approximately 120kg(1176.8N, 264.5 lb) of force, and check for oil leakage in the master cylinder, brake line and each connecting part. Repair the faulty parts as required.

Inspection Of Front Disc Brake Pad 1.

Check the brake pad thickness through the caliper body inspection hole. Pad thickness Standard value : 10.0 mm (0.39 in.) Service limit : 2.0 mm (0.0787 in.)


- If the pad lining thickness is out of specification, left and right pads must be replaced as a complete set. - When the thickness difference between the left pad and right pad is large, check the sliding condition of the piston and the guide rod.

Inspection Of Rear Disc Brake Pad 1.

Check the brake pad thickness through the caliper body inspection hole. Pad thickness Standard value : 9.0 mm (0.35 in.) Service limit : 2.0 mm (0.0787 in.)

- If the pad thickness is out of specification, left and right pads must be replaced as a complete set. - When the thickness difference between the left pad and right pad is large, check the sliding condition of the piston and the guide rod.

Description This specification applies to HCU(Hydraulic Control Unit) and ECU(Electronic Control Unit) of the HECU.(Hydraulic and Electronic Control Unit) This specification is for the wiring design and installation of ABS/ESP ECU. This unit has the functions as follows. - Input of signal from Pressure sensor, Steering angle sensor, Yaw & Lateral G sensor,the wheel speed sensors attached to each wheel. - Control of braking force / traction force / yaw moment. - Failsafe function. - Self diagnosis function. - Interface with the external diagnosis tester. Installation position : engine compartment - Brake tube length from Master cylinder port to HECU inlet port should be max. 1m - The position should not be close to the engine block and not lower than the wheel.

Operation The ECU shall be put into operation by switching on the operating voltage (IGN). On completion of the initialization phase, the ECU shall be ready for operation. In the operating condition, the ECU shall be ready, within the specified limits (voltage and temperature), to process the signals offered by the various sensors and switches in accordance with the control algorithm defined by the software and to control the hydraulic and electrical actuators.

Wheel sensor signal processing The ECU shall receive wheel speed signal from the four active wheel sensors. The wheel signals are converted to voltage signal by the signal conditioning circuit after receiving current signal from active wheel sensors and given as input to the ECU.

Solenoid valve control When one side of the valve coil is connected to the positive voltage that is provided through the valve relay and the other side is connected to the ground by the semiconductor circuit, the solenoid valve goes into operation. The electrical function of the coils are always monitored by the valve test pulse under normal operation conditions.

Voltage limits - Overvoltage When overvoltage is detected(above 17 ± 0.5 V), the ECU switches off the valve relay and shuts down the system. When voltage is returned to operating range, the system goes back to the normal condition after the initialization phase. - Undervoltage In the event of undervoltage(below 9.5 ± 0.5V), ABS control shall be inhibited and the warning lamp shall be turned on. When voltage is returned to operating range, the warning lamp is switched off and ECU returns to normal operating mode.

Pump motor checking The ECU performs a pump motor test at a speed of 30 km/h(18 MPH) once after IGN is switched on.

Diagnostic interface


Diagnostic interface Failures detected by the ECU are encoded on the ECU, stored in a EEPROM and read out by diagnostic equipment when the ignition switch is turned on. The diagnosis interface can also be used for testing the ECU during production of the ECU and for actuating the HCU in the test line of manufactories (Air-bleeding line or Roll and Brake Test line).

Warning lamp module

1.

ABS Warning Lamp module The active ABS warning lamp module indicates the self-test and failure status of the ABS. The ABS warning lamp shall be on: A. During the initialization phase after IGN ON. (continuously 3 seconds). B. In the event of inhibition of ABS functions by failure. C. During diagnostic mode. D. When the ECU Connector is separated from ECU. E. Cluster lamp is ON when communication is impossible with CAN module.

2.

PARKING/EBD warning lamp module The active EBD warning lamp module indicates the self-test and failure status of the EBD. However, in case the Parking Brake Switch is turned on, the EBD warning lamp is always turned on regardless of EBD functions. The EBD warning lamp shall be on: A. During the initialization phase after IGN ON. (continuously 3 seconds). B. When the Parking Brake Switch is ON or brake fluid level is low. C. When the EBD function is out of order. D. During diagnostic mode. E. When the ECU Connector is separated from ECU. F. Cluster lamp is ON when communication is impossible with CAN module.

ABS Control 1.

NORMAL BRAKING without ABS Under the normal braking, voltage is not supplied to solenoid valve, inlet valve is opened and outlet valve is closed.When the brake is depressed, brake fluid is supplied to the wheel cylinder via solenoid valve to activate the brake.When the brake is released, brake fluid is back to the master cylinder via inlet valve and check valve.

Standard flow of diagnostic troubleshooting

Notes with regard to diagnosis The phenomena listed in the following table are not abnormal. Phenomenon System check sound

Explanation When starting the engine, a thudding sound can sometimes be heard coming from inside the engine compartment. This is because the system operation check is being performed.

ABS operation sound 1. Sound of the motor inside the ABS hydraulic unit operation (whine). 2. Sound is generated along with vibration of the brake pedal (scraping). 3. When ABS operates, sound is generated from the vehicle chassis due to repeated brake application and release (Thump : suspension; squeak: tires) ABS operation (Long braking distance)

For road surfaces such as snow-covered and gravel roads, the braking distance for vehicles with ABS can sometimes be longer than that for other vehicles. Accordingly, advise the customer to drive safely on such roads by lowering the vehicle speed.

Diagnosis detection conditions can vary depending on the diagnosis code. When checking the trouble symptom after the diagnosis code has been


erased, ensure that the requirements listed in "Comment" are met.
