Hva betyr feilkoden?
The IAM unit checks the impedance of the speaker in the left rear door and has registered that it is too low. The fault may come from a short circuit between the signal wires or from an internal fault in the speaker, and then the speaker produces no sound.
Mulige årsaker
- The signal wires to the speaker in the left rear door are short-circuited to each other
- Internal fault in the speaker in the left rear door
Hva du kan gjøre
- 1Switch the ignition off and check the connectors at the module and at the speaker in the left rear door for contact resistance, play and oxidation
- 2Follow the two signal wires to the speaker in the left rear door and look for chafing where they may have touched each other
- 3Use a multimeter to check that the signal wires are not short-circuited to each other
- 4If no wiring fault is found, have a workshop check the speaker and replace it if it is damaged
- 5After the work, check that the sound from the speaker in the left rear door works
Symptomer du kan merke2
- No sound from the speaker in the left rear door
- Front and rear parking assistance does not work
