Hva betyr feilkoden?
The IAM unit monitors the signal to the speaker in the left rear door and has registered that it is too low. The signal wire has contact with ground, so the speaker produces no sound and the front and rear parking assistance does not work.
Mulige årsaker

Hva du kan gjøre
- 1With the ignition off, check the connectors at the module and at the speaker in the left rear door for contact resistance, play and oxidation
- 2Follow the signal wire back to the speaker in the left rear door and look for chafing where it may touch the car body
- 3Use a multimeter to check that the signal wire has no contact with ground (the car body)
- 4After the work, check that the sound from the speaker in the left rear door and the parking assistance work and that the fault code does not come back
