Fault code 47

Central locking synchronisation

Diagnostic conditions
- Central locking system in "unlocked position"

Possible cause of fault
- Short circuit to ground/open circuit between alarm system control module and door locks
- Door lock faulty

Affected terminals
Plug A, pins 5, 19, 28, 30 and 32

NOTE: During troubleshooting, the micro switches of the door locks are tested in Step 1. The test is to be used only for vehicles with "safe position". USA vehicles do not have a safe position; "Driver's door secured" and "Passenger's door secured" are therefore displayed during the Input signals test.
