Hva betyr feilkoden?
The IAM unit checks the DC voltage to the antenna amplifier and has registered that it is too low. This is because the supply wire is short-circuited to ground, and radio reception then becomes poor.
Mulige årsaker
- The supply wire to the antenna amplifier is short-circuited to ground
Hva du kan gjøre
- 1Check that the fuses for the antenna amplifier are intact
- 2With the ignition off, check the connectors at the antenna amplifier for contact resistance, play and oxidation
- 3Follow the supply wire to the antenna amplifier and look for chafing or spots where it may touch the car body
- 4Use a multimeter to check that the supply wire has no contact with ground (the car body)
- 5After the work, check that radio reception is good and that the fault code does not come back
