Question
No I don't know how to retrieve codes.

Answer
To get codes:

1. Turn ignition to the ON position. Do NOT start the engine.

2. On the climate control panel, Simultaneously push and hold the OFF and WARMER (^)  buttons for 3 seconds and release them.

3. the codes will appear on your fuel data display in the form of a combination of LETTERS & NUMBERS followed by the letter "H" (history) or the letter "C" (current) for every LETTER & NUMBER that displays until the display finally stops at ECM?


4. Turn OFF ignition.


5. Tell me EXACTLY what displays as if you were video taping it.
