### Removal Procedure

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.

1. Using a scan tool, retrieve the percentage of remaining engine oil. Record the remaining engine oil life.
2. Record the preset radio stations.
3. Turn the ignition OFF.
4. Disconnect the negative battery cable.
5. Remove the rear hood seal.
6. Raise the right side front corner of the air inlet grill in order to access the 4 attachment nuts for the PCM J1 and J2 harness connector boot.
7. Remove the PCM J1 and J2 harness connector boot nuts and move the boot far enough away to access the PCM harness connectors.
8. Disconnect the PCM J1 and J2 harness connectors by unbolting them from the PCM. Pull the harness into the engine compartment.

Important: If a new PCM is being installed, it MUST be reprogrammed with new software and calibrations. Refer to "Service Stall System (SSS) User Guide" for reprogramming procedures. The PCM may be damaged if the reprogramming process is interrupted. Make sure the scan tool is connected securely to the DLC and the vehicle battery has sufficient charge.

Make sure the original PCM has the correct VIN and vehicle options.
16. Reprogram the PCM. Refer to "Service Stall System (SSS) User Guide" for reprogramming procedures.

Important: The new PCM must learn the Passlock password from the BCM. When the PCM reprogram is completed, use the SSS to perform the "Passlock Relearn Procedure."

17. Perform the "Passlock Relearn Procedure" using the SSS.
18. Turn the ignition OFF for 10 seconds.
19. Turn the ignition ON.

Important: Following PCM reprogramming, the PCM will have to learn the crankshaft notch variation for misfire diagnostics.

20. Perform the crankshaft learn procedure. Refer to "Crankshaft Relearn Procedure" under DTC P1336.
21. Verify no DTCs exist. If one exists, refer to the specific DTC diagnostic.
22. Reset the clock and preset radio stations.
