Removal Procedure
Service should normally consist of either replacement of the PCM or electronically erasable programmable read only memory (EEPROM) re-programming.
If the diagnostic procedures call for the PCM to be replaced, the PCM should be inspected first in order to verify the PCM is the correct part. DTC P0602 indicates the EEPROM programming has malfunctioned. When DTC P0602 is set, re-program the EEPROM.
IMPORTANT:
It is necessary to record the remaining engine oil life. If the replacement module is not programed with the remaining engine oil life, the engine oil life will default to 100%. If the replacement module is not programmed with the remaining engine oil life, the engine oil will need to be changed at 5000 km (3,000 mi) from the last engine oil change.
- Using a scan tool, retrieve the percentage of remaining engine oil. Record the remaining engine oil life.
- Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure in Engine Electrical.
- Remove the left closeout/insulator panel. Refer to Closeout/Insulator Panel Replacement - Left in Instrument Panel, Gages, and Console.
- Push down on the locking tab (1) and pull up on the release lever (2) and disconnect the PCM harness connectors.
- Depress the PCM retaining tab (1).
- Slide the PCM up and out from the PCM bracket.
NOTE:
Do not touch the PCM connector pins or soldered components on the circuit board in order to prevent possible electrostatic discharge (ESD) damage. Do not remove the integrated circuit boards from the carrier.
