QUESTION: how do you erase codes?

Answer
The "B" codes are "F" codes.

1. Ignition ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER buttons on your climate control panel for 3 seconds and release them.

3. The codes will appear and stop at .7.0

4. Simultaneously push and hold the OFF and HI buttons until you see E.0.0 and release them. This will clear the "E" codes.

5. Simultaneously push and hold the OFF and LO buttons until you see F.0.0 and release them. This will clear the "F" codes.

6. turn OFF ignition and wait 2 minutes and then re-enter diagnostics and see which codes reappear.
