Answer
Let's check your computers for codes:

1. Ignition ON, engine OFF.

2. Simultaneously push and hold the OFF and WARMER buttons for 3 seconds and release them.

3. FAULT CODES will start to appear.

4. Write them down EXACTLY as they appear.

5. They will stop at PCM?.

6. let me know the codes that appaer.

7. turn ignition OFF.


If you can't write them down fast enough, Just repeat the sequence starting with # 1.
