REMOVAL PROCEDURE

NOTE: In order to prevent internal damage to the PCM, the ignition must be OFF when disconnecting or reconnecting the PCM connector.

Service should normally consist of either replacement of the PCM or 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.

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.

1. Disconnect the negative battery cable.
2. Remove the left closeout/insulator panel.
3. Loosen the powertrain control module (PCM) connector screws (1).

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.

4. Disconnect the PCM electrical connectors.
5. Depress the PCM retaining tabs.
6. Slide the PCM from the PCM bracket.

INSTALLATION PROCEDURE
Remove the new PCM from the packaging and inspect the service number to verify the number is the same number, or an updated number, as the faulty PCM.

1. Slide the PCM into 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.

2. Install the PCM electrical connectors.

NOTE: Refer to Fastener Notice in Service Precautions.

3. Tighten the PCM connector screws (1).

Tighten
Tighten the PCM connector screws to 8 N.M (71 lb ft ).

4. Install the left closeout/insulator panel.
5. Connect the negative battery cable.

IMPORTANT: The replacement PCM must be reprogrammed and the crankshaft position system variation learn procedure must be performed.

6. Program the PCM. Refer to Powertrain Control Module (PCM) Programming. See: Testing and Inspection Programming and Relearning
7. The replacement PCM will NOT allow secondary air injection (AIR) pump operation until a total of 10 miles have accumulated.
It's 1.6hrs labor to replace it time's shop labor rate. It's not too hard to replace you have to have the new one reprogramed.
