Powertrain Control Module Programming and Setup

The powertrain control module (PCM) cannot be programmed with updated software. The correct replacement PCM is already programmed. The following setup procedure below must be performed to write the vehicle identification number (VIN) to the new PCM and to register the ECU communication ID to the theft deterent key transponder to complete the PCM replacement.

PCM Replacement

If the PCM requires replacement, perform the following:

1. Ignition ON with a currently learned master key
2. Access Service Programming System (SPS). On the Select Diagnostic Tool and Programming Process screen, select J2534 Tech 2. Follow all on-screen instructions.
3. On the SPS Supported Controllers screen, select VIN-Write VIN to PCM (J2534). Follow the on-screen instructions.
Clear all codes and cycle the ignition OFF for at least 30 seconds.
4. Remove the scan tool and install a 3 A fused jumper wire between terminal 4 and terminal 13 at the DLC.
5. Ignition ON for 30 minutes.
6. After the 30 minute time period has elapsed, disconnect the jumper wire.
7. Start the vehicle and verify that the Security Light is not illuminated.
