Was bedeutet der Fehlercode?
The IAM unit checks the impedance of the speaker in the right front door and has registered that it is too high. The fault may be a break in the signal wire between the speaker and the module or in the speaker itself, and then the speaker produces no sound.
Mögliche Ursachen
- Break in the signal wire between the speaker in the right front door and the module
- Break in the speaker in the right front door
Was Sie tun können
- 1With the ignition off, check the connectors at the module and at the speaker in the right front door for contact resistance, play and oxidation
- 2Follow the signal wire between the speaker and the module and look for breaks, chafing or loose joints
- 3Use a multimeter to check that the signal wire is not broken
- 4If no fault is found in the wire, have a workshop check the speaker and replace it if it is broken
- 5After the work, check that the sound from the speaker in the right front door works and that the fault code does not come back
