Answer
Lets CLEAR the codes from the computer first:


1. Ignition ON, Engine OFF.

2. Simoultaneously push and hold for 3 seconds the OFF and WARMER buttons on your display panel.

2. Letter/numbers codes will start to appear.

3. When you see PCM? push the UP button for your blower fan and release it.

4. When you see PCM DATA? Push the DOWN button for your blower fan and release it. Do this until you see PCM CLEAR CODES?

5. Push the UP button and wait 3 seconds for the codes to appear and then turn off the ignition.


NOW:

1. Start the engine and let it warm up.

2. Ignition ON, Engine OFF.

3. Simoultaneously push and hold for 3 seconds the OFF and WARMER buttons on your display panel.

4. Write down all the Letter/numbers codes that appear until they stop and turn off the ignition.

5. Let me know what they are.
