Test Point 45
TEST POINT 45
Central Locking Synchronization
Fault Code 46, 47
These faults are stored in the memory if at least one safe contact does not reach the safe position after two synchronization actuations towards
safe.
Fault Effect: No central locking possible
Procedure
1. With PST 2 (drive links), check whether the servo motor reacts with the door closed.
If the servo motors react, select "Driver's side locked" and "Passenger's side locked" in the menu item Input signals, and close the doors
Vehicle not locked
PST 2 display Driver's side not locked
Passenger's side not locked
If the display of the PST 2 deviates from this information or if the servo motors do not react, a fault is present in the supply lead or in the door
lock module (microswitch, servo motor)
2. Pull plug I off the alarm system control module
3. Pull plug off door lock (driver's side / passenger's side)
