Important: The following must be performed anytime the PCM is replaced.

Setup

1. Ensure that the following conditions have been met:

•	The battery is fully charged.

•	The ignition is ON.

•	The scan tool cable connection at the DLC is secure.

2. Program the PCM using the latest software matching the vehicle. Refer to the Techline terminal/equipment users instructions.
3. If the PCM fails to program, proceed as follows:

•	Ensure that all PCM connections are OK.

•	Check the Techline terminal/equipment for the latest software version.

•	Attempt to program the PCM. Replace the PCM if the PCM still cannot be programmed properly.

1. Perform the On-Board Diagnostic System Check.
2. Start the engine and run for 1 minute.
3. Scan for DTCs using the scan tool.
