What does this fault code mean?
The driver or passenger door module (DDM/PDM) monitors the current to the switch lighting in the control panels. The fault is stored when the current on the output is too low, for example from an open circuit or a wire shorted to battery voltage.
Possible causes
- A break in the wire, or the wire touching battery positive
- Contact resistance, oxidation or poor contact in the connections
What you can do
- 1Read and note the code, clear it and road test the car to see whether it comes back
- 2Check that the fuses are intact; see the owner's manual for where they are
- 3Use the buttons or a road test to see whether the switch lighting works
- 4Check that the connectors to the control panel are secure and free from oxidation
- 5Use a multimeter to check that the wire to the control panel is not broken and does not touch battery positive
- 6If you have a diagnostic tool: activate the switch indication and see whether the light comes on; if it does not, have a workshop check the control module
Symptoms you may notice1
