Hva betyr feilkoden?
The steering wheel buttons send their signals to the infotainment control module (ICM) over the LIN bus, and ICM monitors their status. The code is set when the message received does not match the expected one, for example because a checksum is wrong. Fault-finding should then start at the module that transmits the signal.
Mulige årsaker
- The fault lies in the module that transmits the steering wheel button message
Hva du kan gjøre
- 1Check that the fuses are intact. Their locations are given in the owner's manual or on the fuse box cover
- 2Try the steering wheel audio and radio buttons and note which respond and which do not
- 3With a diagnostic tool, read the steering wheel button status in live data and check that the value changes when each button is pressed
- 4If other LIN fault codes are stored in the infotainment system, such as ICM-B108786 or ICM-B108788, work through those first. They point at the LIN bus rather than one specific unit
Symptomer du kan merke2
- Steering wheel buttons for the radio do not work
- Steering wheel buttons for the audio do not work
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
