G1230660t9 : Test 4 Door Latch
NOTE:
If a customer is complaining of issues relating to a door ajar signal e.g. door latch won't lock, or alarm system triggering (indicated via DTC's), there may be several components that generate the fault, including
- Door Latch ajar switch
- Alarm control module
- Central junction box
- Body wiring harness / connectors
- Door wiring harness / connectors
NOTE:
To investigate the functioning of the door ajar switch contained within the door latch, to prove or eliminate the door latch mounted door ajar switch as the root cause, follow the process below. This will prevent the unnecessary replacement of a correctly functioning door latch
1 Remove door trim from door For additional information, refer to Front Door Trim Panel Service and Repair
For additional information, refer to Rear Door Trim Panel Service and Repair
2 Remove module plate / closing panel from door
3 Remove latch module from door For additional information, refer to Front Door Latch Service and Repair
