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 of the should normally consist of either replacement of the PCM or EEPROM reprogramming.
If the diagnostic procedures call for the PCM to be replaced, the PCM should be inspect first in order to verify the PCM is the correct part.
DTC P0601 indicates the EEPROM programming has malfunctioned. When DTC P0601 is set, reprogram the EEPROM.
CAUTION: Refer to Battery Disconnect Caution in Service Precautions.
1. Disconnect the negative battery cable.
2. Remove the left hush panel.
3. Loosen the 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. Remove the PCM retainer.
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.
2. Install the PCM retainer.
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.
3. Install the PCM electrical connectors.
4. Tighten the PCM connector screws (1).
5. Install the left hush panel.
6. Connect the negative battery cable.
IMPORTANT: The replacement PCM must be reprogrammed and the crankshaft position system variation learn procedure must be performed.
7. Program the PCM. Programming and Relearning
8. The replacement PCM will NOT allow Secondary AIR Pump operation until a total of 10 miles have accumulated.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
