Was bedeutet der Fehlercode?
The climate control module (CCM) checks the buttons in the bottom row of the keypad. If a button has been held down for too long, leaving its signal stuck at a low level, the fault code is set. The fault is caused by one or more function buttons being stuck in the pressed position, so functions controlled from the keypad cannot be used.
Mögliche Ursachen
- At least one function button is jammed down
Was Sie tun können
- 1Read off and clear the fault code, then road test the car to see whether it returns
- 2Check that the fuses for the affected functions are intact
- 3Feel whether any button in the bottom row is stuck down or feels sticky
- 4Use a multimeter to check that the wires to the keypad have no contact with ground (the body)
- 5With diagnostic equipment, follow the status of the bottom-row buttons in live data while you press each one. A button whose status does not change is the likely cause
- 6If the fault remains after these checks, have a workshop check or replace the keypad
