Power Locks: Testing and Inspection
Central locking, function testNotes:
- If system is operating properly, all locks must lock after approximately 2 seconds. If bi-pressure pump runs for longer than 5 seconds system is leaking.
- If bi-pressure pump switches off after about 5 seconds and then starts to run again after 12 seconds, at least one door lock knob has not retracted, or switch-off point in positioning element has not been reached.
Operation check
Requirements:
- Doors, rear lid and tank flap closed.
- Windows fully open.

Anti-theft system, checking
Requirements:
- Doors, rear lid and tank flap closed.
- Windows open.
Checking:
- Lock driver's door with key and pull up all lock knobs within 12 seconds.
- 12 seconds after locking, pump must run, all doors will be locked again.
- After an additional 15 seconds pull all lock knobs up one after another (wait 24 secs. after locking with key).
- It must not be possible to pull lock knobs up to unlocked position. Bi-pressure pump runs and pulls lock knobs down. At same time, door lock is decoupled and it is no longer possible to open door.
- When this happens, a clicking noise is audible (safety coil decouples door locks).
- Doors are locked, rear lid and tank flap are locked.
- Repeat test procedure starting with front passenger door.
