No: TSB-03-13-009DATE: December, 2003
MODEL: 2002-03 Lancer
SUBJECT:
PCM REPROGRAMMING FOR DTC P0507
This TSB supercedes TSB-02-13-006, issued March, 2002, which should be discarded.
This TSB includes all 2002 and 2003 Lancer models, a new PCM update software, and MUT-III reprogramming instructions.
PURPOSE
Incorrect PCM software parameters may cause Diagnostic Trouble Code (DTC) P0507 to set in the PCM and turn on the "SERVICE ENGINE SOON" light. Reprogramming the PCM as described in this bulletin will eliminate this condition.
If the vehicle was already reprogrammed with the previous database (as described in TSB-02-13-006), DTC P0507 could incorrectly re-set under certain driving conditions. The vehicle must be reprogrammed again using the new reprogramming database in this TSB.
For details on reprogramming with the MUT-III scan tool, refer to TSB-03-00-015.
AFFECTED VEHICLES
2002 and 2003 Lancer models (EXCEPT Evolution)
PROCEDURE
CAUTION
BATTERY VOLTAGE (AS MEASURED AT THE BATTERY POSTS WITHOUT ELECTRICAL LOAD) MUST BE 12.4V OR HIGHER IN ORDER TO REPROGRAM THE PCM.
1. Using the MUT-III scan tool, check to see if any DTCs are set in the PCM.
If any DTC is set, follow the appropriate DTC troubleshooting and repair instructions in the service manual.
2. Use the MUT-III to erase all DTCs set in the PCM.
3. Turn the ignition key to OFF and disconnect the MUT-III.
4. Gather the following reprogramming equipment:
5. Transfer the reprogramming data from the DVD-ROM to the memory card.
6. Remove the memory card from the laptop and install it in the VCI.
7. Reprogram the PCM, using automatic reprogramming. For reprogramming details, refer to TSB-03-00-015.
CAUTION
DO NOT DISTURB THE HARNESS CABLES OR CONNECTIONS. INTERRUPTION DURING THE PROGRAMMING PROCESS COULD CAUSE THE PCM TO LOSE DATA OR PREVENT FUTURE PCM REPROGRAMMING.
8. Using a ball-point pen, enter the appropriate PCM pant number, vendor number, ROM ID#, this TSB number (TSB-03-13-009), your dealer code, and the current date on the Engine Compartment and Control Module Labels (part no. MSSF-024G-00).
NOTE:
Attachment A lists this information for affected vehicles.
9. Carefully remove all dirt and oil from a vacant area near the VECI label on the underside of the hood and affix the Engine Compartment label.
10. Affix the Control Module label to the PCM.
