ELECTRIC SLIDING SIDE DOORS NOT WORKING

The sliding side doors (NPS) open manually but not automatically (electric operation).

The vehicle uses a door activation and deactivation system with the transfer of data via special CAN/VAN networks. The command for opening the door lock motors depends on the Body Computer.

If the ABS is faulty, the side doors do not open automatically with the engine running.
