5.2 Central Locking System

The central locking system consists of a special bi-pressure pump in the luggage compartment, connected by vacuum hose to lock activators at each of the doors, at the rear lid, and at the gas tank flap. When the key is turned in the driver's door lock, the master activator turns on the pump to supply pressure to open the locks, or vacuum to close them.

This heading covers only the removal and installation of the mechanical parts, and troubleshooting of the bi-pressure system. If the pump does not run when key is turned, the problem may be electrical. Troubleshoot the pump and the master activator as described in ELECTRICAL SYSTEM.
