•

For supported ECMs, this eliminates the need to send the ECMs back to Caterpillar for clearing.

•

Within Cat ET, ECM Test Mode can be utilized on ECMs not supported by the ECM Clearing process.

•

ECM Clearing is supported on the A4E2V1, A4E4V2, and A4E4V3 Engine ECMs.

•

NOTE: Cat ET 2013C or newer is required


•

Please check your A4E2V1, A4E4V2, and A4E4V3 ECMs to verify clearing compatibility

•

–

•

The suffix code on the outside of the ECM should match one in the list. [last two digits of ECM Serial number]


JZ, LA, LC

A4E4V2 Suffix Codes: –

• •

A4E2V1 Suffix Codes:

JV, JW, JX, JY, LS, JL, JM

A4E4V3 Suffix Codes: –

LF, LG, LH, LJ, LK, LL, LM, MC, MD, ME, MF, RA, RB, RC, RD, RE

•

Please note that the ECM Clearing process will need to be performed using the J1939 datalink. Clearing process will NOT work on the CDL Datalink

•

Please ensure that the breakout harness being used to clear the ECM conforms to the appropriate schematic below.


•

Navigate to Winflash Hint: Prior to clearing the ECM, the user may want to record the engine serial number as well as the previously loaded flashfile. In the event of an issue, this information will assist the troubleshooting process.

•

Click the Utilities menu, and choose “Clear ECM Memory” option. This updates the ECM list to only show ECMs supported by the ECM Clearing Process. Note: This step also ensures that SIS flashfile search feature within Winflash, will direct the users to the proper file in SIS.

Note: The Clear ECM Memory option is only available if Cat ET detects an ECM that is compatible with the clearing process. Caterpillar: Confidential Yellow

•

Once the list of ECMs is updated, users will be prompted with a dialog box, alerting them that this process is not authorized to work with Factory Installed ECMs.

•

Clicking yes will take the user to FPS to verify if the ECM was factory installed.

•

Clicking No, or closing the FPS window after clicking yes, will allow the user to continue the ECM clearing process


•

Next the user must navigate to, and load the proper ECM clearing file. Note: Files can be obtained from SIS, saved to the hard drive, and then loaded into Winflash. Selecting the magnifying glass in Winflash, next to the ECM will automatically launch SIS and take the user to the flashfile search page, where the clearing file can be obtained. Once the file is loaded, click the “Begin Flash” button on the lower left hand side of the screen.

•

Note: Do not interrupt power during the clearing process. The ECM could become corrupt and un-usable


•

Once the flash successfully completes, click the “Cat ET” button to return to Cat ET and continue the ECM Clearing Process


•

The following screen appears. Following the instructions on the screen, click the “Clear Memory” button to continue the process.

•

Be sure to only use the “Clear Memory” button. The Clear ECM Memory option that is available under the menus, will only navigate the user back to this screen.


•

Click the “Yes” button to confirm and continue on with the process.


•

The user will then be prompted for a Factory Password to continue. Please follow your standard method for obtaining Factory Passwords.

•

Then Click the “OK” button once the passwords have been entered.

•

TC names will need to be entered into a database to allow ECM Clearing password generation. Please send TC information to: – Jim Snodgrass: • •

•

The following message will appear. Please click “OK” to continue on. Cat ET will then disconnect.

•

Please “key cycle” ECM

•

At this point: – – –

The software has been removed from the ECM. A default Interlock of 43690 has been programmed. The ECM is ready to be used for another ECM replacement or returned to Dealer Stock.

Note: It is highly recommended that a sticker or some other designation be marked on the ECM before placing it back into stock, to indicate that it is a cleared ECM, and not a brand new ECM.



•

Prior to flashing an ECM the user needs to verify that the Interlock Code (IC) is currently available in Feature Protection System (FPS).

•

To verify the IC: • Navigate to https://fps.cat.com • Under the Pricing tab, choose the “Estimate Feature Cost” • Select RC-5 under the feature dropdown and then enter the rest of the data. This example shows serial number LHX21111 (in Serial Number box) going to the IC of 116 (in both the Old Value and the New Value). • Then click “Submit”.




•

If the user receives an error stating that an IC is not set up in FPS, first, verify that the correct Flashfile is being used. If the correct flashfile is being used and the user is still receiving an error, please have your TC contact Jim Snodgrass with the following information: • Full Engine Serial Number • Flashfile part number to flash on the ECM

•

•

As the database is populated and rule sets are created in FPS, this error will become less common. For the time being, this step will help eliminate wasted time while obtaining Reason Code 5 passwords during the flashing process.


•

In order to flash a new application software file onto the ECM, the user must reconnect Cat ET to the ECM.

•

When Cat ET reconnects, the user will see this screen. Please click the “WinFlash” button to continue.


•

The user may now flash a new application file onto the ECM following standard process. Note: Files can be obtained from SIS, saved to the hard drive, and then loaded into Winflash


•

Once the flash successfully completes, click the “Cat ET” button to return to Cat ET and continue the ECM Clearing Process


•

The personality mismatch box will appear. Click “Cancel” to ignore this message. This allows the user to navigate to the Configuration screen for continuation of the process.

•

If the user clicks “OK”, they may fall into a “loop” of screens and the process will not work properly. If this happens, simply disconnect Cat ET, and then Re-Connect Cat ET, and they will be able to start over by pressing “Cancel” on the Personality Module Mismatch screen.


•

Next, the user must navigate to the configuration screen in Cat ET.

•

Once on the configuration screen, the user will need to program the appropriate serial number for the engine that the ECM will now be loaded on. Caterpillar: Confidential Yellow

•

Once the user clicks “OK”, they will need to Disconnect Cat ET and then Reconnect Cat ET.

•

Once reconnected, the personality mismatch box appears again. This time the user must click “OK”.


•

The user will then click “OK” to continue on.


•

The user is then prompted for a Factory Password to continue. Please follow the standard method for obtaining Factory Passwords.

•

Then Click the “OK” button once the passwords have been entered. Note: These passwords are required to remain in emissions compliance


•

The ECM has now been successfully cleared, reflashed, and had the serial number programmed to a new application flashfile.

For assistance, please complete the DSN (Dealer Solution Network) online password request form(click HERE) and provide it to your Technical Communicator (TC) for entry into the DSN. Before requesting passwords, please ensure the correct engine serial number is programmed into the ECM. Also, provide a detailed story of failure or reason for denial of passwords.The engine rating is not available. •

For assistance, please contact the Truck Engine Call Center at 309-578-3901 (Direct or International) 1800-447-4986 (within North America only) Email: [email protected]. Please note e-mails must be followed by phone confirmation.The engine rating is not available. •

–

Cause: Ruleset not set up for the rating they are trying to change to. This is the message seen for everything except Onhighway and Reman engines.

Cause: Ruleset not set up for the rating they are trying to go to. This is the message seen for On-highway and Reman engines.

Requested rating change for this engine serial number does not match the last rating change in FPS history OR does not match the 'As Shipped' from TMI. This transaction will be included in the audit report for cleared ECMs. Do you want to proceed with this transaction? •

Cause: Ruleset is set up, there is no history in FPS or PSPS/TMI (factory) showing this rating was previously on the engine.
