Any repair performed after warranty expiration may be eligible for goodwill consideration by the District Parts and Service Manager or your Zone Office. You must request consideration, and get a decision, before starting work.

REPAIR PROCEDURE

1. Retrieve the PCM broadcast code with the PGM Tester or the Smart Cable (refer to Service Bulletin 99-005, Updathg the Passport PCM).





2. Compare the retrieved code with the listed codes.

^ If the code is in the list, go to step 3.

^ If the code is not in the list, the PCM has already been updated. Troubleshoot other causes for the detonation.

NOTE:
Since the Smart Cable may need to be cleared from a previous PCM update or the Smart Cable firmware may need to be reprogrammed, always begin each PCM update at the iN workstation.

3. Update the PCM software with the Smart Cable. For instructions, refer to Service Bulletin 99-005.

NOTE:
Make sure you select the most recent broadcast code from the list on the iN screen that applies to the model year, transmission type, and emission level. This code is not necessarily at the top of the list since the most recent code is the last one in the alphabetical sequence, letter by letter.

4. Use the PGM Tester to clear any DTCs set during programming.





5. Retrieve the broadcast code. Make sure it does not match any of the codes in the list in step 2 (indicating the PCM has been updated) and that it applies to the model year, transmission type, and emission level for the vehicle. The broadcast code should match a code in the list below.
