Test Point 4

Position of the Drives Implausible

- This fault is also stored if, for example, the driver's door is open when the key is used to actuate the central locking system from the passenger's door.

- Check position switch at drive link:

1. Disconnect connections T 7 (driver's side) and T 11 (passenger's side). Use a jumper wire to connect terminal 1 on pin side to ground. Use an ohmmeter to check terminals 4 and 6 (pin side) for continuity to ground.

At terminal 4, continuity to ground (0 - 5 ohms) is present if door is locked.

At terminal 6, continuity to ground (0 - 5 ohms) is present if door is unlocked.

If no continuity is displayed, disconnect plug at drive link.

2. Using an ohmmeter, check if continuity is present from terminal 3 to terminal 2 and from terminal 3 to terminal 4. Continuity from terminal 3 to terminal 2 is present if door is locked.

Continuity from terminal 3 to terminal 4 is present if door is unlocked.

- Check connection from T 7, terminal 4, to T 11, terminal 4, for continuity.

- Check connection from T 7, terminal 6, to T 11, terminal 6, for continuity.

- Check connection from T 7, terminal 4, to control unit plug II, terminal 12, for continuity.

- Check connection from T 7, terminal 6, to control unit plug II, terminal 10, for continuity.

- Check triggering of drive links (actuators). Connectors T 7 and T 11, terminal 8 and terminal 10, must be grounded in the quiescent state. Positive voltage must be present at terminal 8 if the drive link is triggered in the "open" direction.

Positive voltage must be present at terminal 10 if the drive link is triggered in the "closed" direction.

Note: The drive links (actuators) are triggered for a few milliseconds only.

- Check wiring from control unit plug I, terminal 11 and terminal 12, to drive links for continuity.
