What does this fault code mean?
The fault code is labelled bus off, but it concerns an open circuit in the circuit to the left front damper solenoid. The solenoid therefore has no complete circuit, and Four-C is switched off.
Possible causes
- Poor contact from oxidation or contact resistance in the connectors
- Open circuit in the power supply wire
- Open circuit in the solenoid's return wire
- Damaged solenoid
What you can do
- 1Check the connectors at the damper and at the control module for looseness, oxidation or poor fit
- 2Use a multimeter to check that the wires to the solenoid are not broken, with the ignition switched off
- 3Read the fault status after the test drive to see whether the fault remains
- 4If the wires are sound: have a workshop check the solenoid return wire and replace the solenoid if needed
Symptoms you may notice2
