DESCRIPTION
Some vehicles may experience a MIL that comes on with DTC P0462 in memory with no other symptoms. This will occur when the fuel tank is at or
near empty.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1.
Reboot the IDS to clear memory before reprogramming.
2.
Using IDS 47.3 or later software, reprogram the PCM to the latest calibration (refer to "Calibration Information table") by following the "Module
Reprogramming" procedure.
NOTE:
^
Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for PCM reprogramming.
^
It is not necessary to remove any fuses or relays during PCM reprogramming when the IDS screen prompts you to do so. You may
accidentally stop power to one of the PCM terminals and cause the PCM to be blanked, or you may receive error messages during the IDS
reprogramming procedure.
^
IDS shows the calibration part numbers after programming the PCM.
^
Please be aware that PCM calibration part numbers and file names listed in any Service Bulletin may change due to future releases of IDS
software, and additional revisions made to those calibrations for service related concerns.
^
When reprogramming a PCM, IDS will always display the "latest" calibration P/N available for that vehicle. If any calibration has been
revised/updated to contain new information for a new service concern/issue, it will also contain all previously released calibrations.
^
When performing this procedure, we recommend that a battery charger be installed on the vehicle battery and turned ON to a maximum
charge of no more than 20 AMPS to keep the vehicle battery up to capacity. If you exceed 20 AMPS, it could damage the VCM.
3.
After performing the PCM reprogramming procedure, verify the repair by starting the engine and making sure there are no MIL illumination or
abnormal warning lights present.
NOTE:
^
If any DTCs should remain after performing DTC erase, diagnose the DTCs according to the appropriate Troubleshooting section of the
Workshop Manual.
^
After PCM reprogramming, it is no longer necessary to road test the vehicle to "relearn" KAM (Keep Alive Memory).
4.
Fill out an "Authorized Modifications" label (P/N 9999-95-AMDC-97) with the new PCM calibration information, your dealer code, and today's
date.
5.
Place the "Authorized Modifications" label on the radiator support next to the Emission Control sticker. The Authorized Modification label will
inform technicians of the PCM calibration change if future repairs are necessary.
