CENTRAL LOCKING ALARM NOT WORKING

(Version Without Keyless Go). The alarm comes on normally but the doors not lock lock;

The alarm system comes on automatically the moment the doors are locked using the remote control.

The command to lock the doors and boot comes from the Body Computer Node to the Driver's Door Node, Passenger Door Node and Luggage Compartment Node.

If one of the doors is not properly shut or the door sensor is signalling this condition, the door cannot be properly locked and this is signalled by a warning beep and the flashing of the direction indicators and the door LEDs for 3 seconds
