Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Calibration Mode
The A/C-heater control must be calibrated if the battery has been disconnected or discharged, a stepper motor replaced, or if the A/C-heater control panel has been replaced. The calibration and self-test are carried out by simultaneously pressing AUTO and OFF push button. The calibration and self-test takes less than 30 seconds.
All stored faults are cleared at the start and while calibration and self-test are in progress. The number of faults found will be shown on the A/C-heater control panel display.
