Powertrain Control Module: Notes

NOTE: In order to prevent internal damage to the Powertrain Control Module (PCM), the ignition must be OFF when disconnecting or reconnecting the PCM connector. Service should normally consist of either replacement of the PCM or Electrically 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.
NOTE: There are no user serviceable parts in this PCM. The PCM should never be opened for any reason. When replacing the production PCM with a service PCM (controller), it is important to transfer the broadcast code and production PCM number to the service PCM label. Do not record this information on the PCM cover. Transfer allows positive identification of PCM parts throughout the service life of the vehicle.
