Aurora V6-214 3.5L VIN H SFI (2001)
Powertrain Control Module: Service and Repair
Powertrain Control Module (PCM) Replacement
Service of the powertrain control module (PCM) should normally consist of either replacement of the PCM or EEPROM programming. If the diagnostic
procedures call for PCM replacement, check the PCM first to see if the PCM is the correct part. If the PCM is faulty, remove the PCM and install the
new service PCM.
The new service PCM will not be programmed. You must program the new PCM. DTC P0602 indicates the EEPROM is not programmed or has
malfunctioned.
NOTE:
^
In order to prevent possible electrostatic discharge damage to the PCM, do not touch the connector pins or soldered components on the circuit
board.
There are no user serviceable parts in this PCM. The PCM should never be opened for any reason.
^
Turn the ignition OFF when installing or removing the PCM connectors and disconnecting or reconnecting the power to the PCM (battery cable,
PCM pigtail. PCM fuse, jumper cables, etc.) in order to prevent internal PCM damage.
IMPORTANT: When replacing the production PCM with a service PCM, it is important to transfer the broadcast code and production PCM number to
the service PCM label. Do not record the information on the PCM cover. This will allow positive identification of the PCM parts throughout the service
life of the vehicle.
Removal Procedure
CAUTION: Refer to Battery Disconnect Caution in Service Precautions.
1. Disconnect the negative battery cable.
2. Remove the left strut brace.
3. Loosen the band clamp (2) at the throttle body (1), and disconnect the air duct (3) from the throttle body.
