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 PCM. Programming and Relearning

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. Programming and Relearning
18. Ignition Off for 10 seconds, ignition On.

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