General Description AIRBAG SYSTEM (DIAGNOSTICS)

3. General Description

• When checking, use a test harness (1). Do not directly apply the tester probe to any connector terminal of the airbag.

A: CAUTION • When servicing a vehicle, be sure to turn the ignition switch to OFF, disconnect the ground cable from battery, and wait for more than 20 seconds before starting work. • The airbag system is equipped with a backup power source. If the airbag system is serviced within 20 seconds from the ground cable is disconnected, it may inflate.

(1)

IN-00203

• If sensors, airbag module, airbag control module, pretensioner and harness are deformed or damaged, replace them with new parts.

AB-00122

• Do not drop the airbag module, subject them to high temperature over 93°C (199°F), or let water, oil or grease get on them; the internal parts may be damaged and reliability is greatly lowered.

AB-00120

• Do not use the airbag system and pretensioners on other vehicles. When replacing parts, be sure to replace them with new ones. • When checking the airbag system, be sure to use a digital circuit tester. Use of an analog circuit tester may cause the airbag to activate erroneously.

AB-00123

AB-00121

AB(diag)-4


• If any damage, opening or rust is found on the airbag system wire harness, do not attempt to repair using soldering equipment. Be sure to replace the faulty harness with a new genuine part.

• The airbag module cannot be used again if once deployed.

AB-00127 AB-00124

• Install the wire harness securely with the specified clips to avoid interference or tangled up with other parts.

• After removal, keep the airbag module with the pad facing upward on a dry, clean and flat surface away from heat, light sources, moisture and dust.

AB-00056

AB-00125

• Do not allow water or oil to come in contact with the connector terminals. Do not touch the connector terminals.

• Do not check continuity of either of the airbag modules for driver, passenger, side or curtain, or pretensioner.

AB-00006 AB-00126

• Either of the airbag modules for driver, passenger, side or curtain, or pretensioner must not be disassembled.

AB(diag)-5


• The removed front seat with an airbag module must be kept at least 200 mm (8 in) away from walls and other objects.

(1)

AB-00128

(1) 200 mm (8 in) or more

• When painting or performing sheet metal work on the front part of the vehicle, including the front wheel apron, front fender and front side frame, remove the front sub sensors and wire harness of the airbag system. • When painting or performing sheet metal work on the side of the vehicle, including the side sill, center pillar and front and rear doors, remove the side airbag sensors and wire harness of the airbag system.

AB-00129

• Do not discard undeployed airbag modules. They could easily cause a serious accident if accidentally deployed.

AB(diag)-6


• When storing a removed airbag module, do not place any objects on it or pile airbag modules on top of each other. If the airbag inflates for some reason when it is placed with its pad side facing downward or under any object, a serious accident may result. (1)

Step CHECK CURTAIN AIRBAG MODULE. 1) Turn the ignition switch OFF, disconnect the battery ground terminal, and wait more than 20 seconds. 2) Disconnect the connector (AB31) from (AB39), and connect the connector (1F) in test harness F to connector (AB31). 3) Connect the airbag resistor to connector (3F) in the test harness F. 4) Connect the battery ground terminal and turn the ignition switch ON. CHECK AIRBAG REAR HARNESS (CURTAIN AIRBAG MODULE HARNESS LH). 1) Turn the ignition switch OFF, disconnect the battery ground terminal, and wait more than 20 seconds. 2) Disconnect the connector (AB21) from seat belt pretensioner (LH). 3) Disconnect the connector (AB19) from side airbag module (LH). 4) Disconnect the airbag resistor from the test harness F. 5) Disconnect the connector (AB17) from airbag control module. 6) Connect the connector (1U) in the test harness U to connector (AB17). 7) Measure the resistance between connector (5U) in the test harness U and connector (3F) in the test harness F. Connector & terminal (5U) No. 1 — (3F) No. 4: (5U) No. 3 — (3F) No. 3: CHECK AIRBAG REAR HARNESS (CURTAIN AIRBAG MODULE HARNESS LH). Measure the resistance between connector (5U) terminals in the test harness U. Connector & terminal (5U) No. 1 — (5U) No. 3: CHECK AIRBAG REAR HARNESS (CURTAIN AIRBAG MODULE HARNESS LH). Measure the resistance between the terminals of connector (3F) in the test harness F. Connector & terminal (3F) No. 3 — (3F) No. 4: CHECK AIRBAG REAR HARNESS (CURTAIN AIRBAG MODULE HARNESS LH). Measure the resistance between connector (3F) in the test harness F and chassis ground. Connector & terminal (3F) No. 3 — Chassis ground: (3F) No. 4 — Chassis ground: CHECK AIRBAG REAR HARNESS (CURTAIN AIRBAG MODULE HARNESS LH). Measure the resistance between connector (5U) in the test harness U and chassis ground. Connector & terminal (5U) No. 1 — Chassis ground: (5U) No. 3 — Chassis ground:

AK:DTC 95 DTC DETECTING CONDITION: • Curtain airbag harness (RH) is shorted to power supply. • Airbag control module is faulty. CAUTION: • Before diagnosing the airbag system, be sure to turn the ignition switch OFF, disconnect the ground terminal from battery, and wait more than 20 seconds before starting to work. • Before replacing the airbag module, seat belt pretensioner, roll connector, control module and sensor, reconnect each part and confirm that the warning light operates properly. • When inspecting the airbag main harness, disconnect the airbag module connector of the driver’s and passenger’s seats for safety reasons. • When inspecting the airbag rear harness, disconnect the side airbag module connector, curtain airbag module connector and seat belt pretensioner connector for safety reasons.

Step Check CHECK CURTAIN AIRBAG MODULE. Does the airbag warning light 1) Turn the ignition switch OFF, disconnect the operate properly? battery ground terminal, and wait more than 20 seconds. 2) Disconnect the connector (AB33) from (AB40), and connect the connector (1F) in test harness F to connector (AB33). 3) Connect the airbag resistor to connector (3F) in the test harness F. 4) Connect the battery ground terminal and turn the ignition switch ON. Is the voltage less than 1 V? CHECK AIRBAG REAR HARNESS (CURTAIN AIRBAG MODULE HARNESS RH). 1) Turn the ignition switch OFF, disconnect the battery ground terminal, and wait more than 20 seconds. 2) Disconnect the connector (AB26) from seat belt pretensioner (RH). 3) Disconnect the connector (AB24) from side airbag module (RH). 4) Disconnect the airbag resistor from the test harness F. 5) Disconnect the connector (AB18) from airbag control module. 6) Connect the connector (1U) in the test harness U to connector (AB18). 7) Connect the battery ground terminal and turn the ignition switch ON. 8) Measure the voltage between connector (5U) in the test harness U and chassis ground.
