Checking for permanent or intermittent faults
Simulate the door closing by pressing in the striker plate in the lock and check to see if door warning lamp goes off.
Does door warning lamp go off?
Yes - Intermittent fault
No - Checking for a short circuit
-------------------------------------------------
Checking for a short circuit
Check the wire between door control unit 7A and door warning lamp 1 for a short circuit to voltage supply as described in Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Check the wire between door warning lamp 2 and the ground point for a short circuit to voltage supply as described in Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
If a fault is found, replace the wire.
If wire is OK: Test with a new door warning lamp.
Additional information:
- With ignition on and door open but striker plate in door depressed, voltage between control unit 7 (to door warning lamp) and ground should be 0 V
- To connect the test box, see Connecting the breakout box Connecting the Breakout Box
- For information on signals and additional values, see Signal specification Signal Specification, Driver Door Module (DDM) / Passenger Door Module (PDM)
- To access the door control unit, see Driver's door module / passenger door module (DDM/PDM), replacing Driver's Door Module/Passenger Door Module (DDM/PDM), Replacing
- To access/replace door warning lamp, see Bulb, warning lamp, side door, replacing Service and Repair.

Intermittent fault
Check door control unit and door warning lamp connectors for contact resistance and oxidation as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check the wire between door control unit 7A and door warning lamp 1 for an intermittent short circuit to voltage supply as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults , and for an intermittent open circuit as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check the wire between door warning lamp 2 and the ground point for an intermittent short circuit to voltage supply as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults , and for an intermittent open circuit as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
If wire is OK: Test with a new door warning lamp.

Verification
Hint: After the repair it is necessary to check that the fault has been rectified.
- Ignition off.
- Connect the connectors, install the components, etc.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit Fault-Tracing
No - Attempt New Test

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
