Powertrain Control Module (PCM) - Programming

PCM Programming

1. Perform the following steps in order to prepare for programming the VCM (EEPROM).
^ Make sure that both the Tech 2 and the Techline terminal software are updated to the most current level.
^ Verify that the vehicle battery is properly charged prior to performing the reprogramming process.
^ Make sure the connection at the Data Link Connector (DLC) is secure.
^ Turn ON the ignition.
^ Turn OFF all the accessories (i.e., radio, HVAC controls, interior lamps, etc.).
2. Refer to the Techline terminal and follow the user's instructions for VCM programming.
3. If the VCM fails to program, perform the following functions:
^ Check all the VCM connections.
^ Try again to program the VCM. If the programming fails again, replace the VCM.
4. Perform the PASSLOCK Reprogramming Seed and Key Procedure. Refer to PASSLOCK Reprogramming Seed and Key in Antitheft and Alarm Systems.
5. Perform the CKP System Variation Learn Procedure. Refer to CKP System Variation Learn Procedure. Programming and Relearning
6. For a functional check, perform the Powertrain On-Board Diagnostic (OBD) System Check.
