Hva betyr feilkoden?
The radio receiver (RDAR) compares its supply voltage with the reading from the central electronic module (CEM) and has registered a deviation. The fault can come from contact resistance or a damaged supply cable, and then the digital radio does not work.
Mulige årsaker
- Contact resistance in the supply
- Damaged supply cable
Hva du kan gjøre
- 1Check that the fuse for the digital radio is not blown or half burned by temporarily fitting a new fuse
- 2With a multimeter, check that the supply voltage reaches the receiver. If it is missing, check the connectors and the cable for breaks and poor contact
- 3Check that the battery is in good condition and that its terminals are tight
- 4Clear the code and road test the car. If it returns, have a workshop carry on with the fault-tracing
