The infotainment control module (ICM) reads the signal circuit for the CD, AM/FM, << and >> buttons on the left-hand keypad. The fault code is set when the signal is too high or too low, and the buttons may then stop working.

- Short circuit to ground or open circuit in the wire to the keypad
Hva du kan gjøre
- 1Read the code, clear it and press the CD, AM/FM, << and >> buttons to see whether they respond
- 2Look over the plugs linking the left-hand keypad to the infotainment control module for contact resistance, oxidation or play, and for damage
