Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- 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
Co możesz zrobić
- 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
