Hva betyr feilkoden?
The ICM monitors the signal circuit for the up, down and CD eject buttons on the right-hand keypad. The fault code is set when the signal is too high or too low, and those buttons may stop working.
Mulige årsaker
- Short circuit to ground or open circuit in the right-hand keypad
- Short circuit to ground or open circuit in the wire to the keypad
Hva du kan gjøre
- 1Press the up, down and CD eject buttons and see whether any of them gives no response
- 2Read the code, clear it and check whether it returns after a test drive
- 3Inspect the plugs for the right-hand keypad for contact resistance, oxidation, play and damage
- 4Use a multimeter to check that the wire to the keypad has no contact with ground and is not broken; if no fault is found, a workshop can try a new keypad
Symptomer du kan merke1
- The buttons on the right-hand keypad do not work
