I am getting the following fault code from Durametric - anyone know what this is for?



Rear left door control module

No signal / Communication

Fault code 1333 Rear left door control unit

Possible causes of fault

- Rear left door control unit faulty

- No signal/communication (no signal from rear left door control unit on CAN comfort)

- Rear left door control unit does not function (Upper voltage value of vehicle battery exceeded)

- Rear left door control unit does not function (Lower voltage value of vehicle battery not reached)

Check first that the affected pins on the rear left door control unit plug connection are neither damaged nor corroded.

Agree with low battery causing central locking issues. Initial checks showed fault with right rear door control module and inoperative central locking right front and rear doors. Connected battery charger and continued diagnostics - after about 15 minutes there were no faults and the central locking was working normally. Battery tested at 285CCA, so new one to be fitted.
