Functional Check

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

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