Hva betyr feilkoden?
The IAM unit checks the signal between the antenna amplifier and the window antennas and has registered that the signal is missing or faulty. The fault is a break or a short circuit to ground on the signal wire, and radio reception then gets worse.
Mulige årsaker
- Break or short circuit to ground on the signal wire between the antenna amplifier and the window antennas
Hva du kan gjøre
- 1Check that the fuses for the radio are intact
- 2With the ignition off, check the connections at the antenna amplifier and at the window antenna for contact resistance, play and oxidation
- 3Follow the signal wire from the antenna amplifier to the window antennas and look for breaks, chafing or spots where it may touch the car body
- 4Use a multimeter to check that the signal wire is not broken and has no contact with ground (the car body)
- 5After the work, check that radio reception is good on both AM and FM
Symptomer du kan merke2
- Poor AM radio reception
- Poor FM radio reception
