Programming and Relearning

Reprogramming of the PCM is done without removing it from the vehicle. This provides a flexible and cost-effective method of making changes in software calibrations.

Refer to the latest Techline information on reprogramming or flashing procedures.

EEPROM Programming
1. Step-up - Ensure that the following conditions have been met:
- The battery is fully charged.
- The ignition is "ON".
- The Vehicle Interface Module cable connection at the DLC is secure.

2. Program the PCM using the latest software matching the vehicle. Refer to up-to-date ITCS equipment user's instructions.

3. If the PCM fails to program proceed as follows:
- Ensure that all PCM connections are OK.
- Check the ITCS equipment for the latest software version.
- Attempt to program the PCM. If the PCM still cannot be programmed properly replace the PCM. The replacement PCM must be programmed.

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