Component Tests and General Diagnostics

CHECKING CONTROLS OF POWER SUN ROOF DRIVE

1. Check fuse no.8 (8 amps).




2. Take sun roof switch out of center console with help of a spatula. Unfold plug connection cover for switch.

3. Perform following tests with a voltmeter or test lamp.

3.1 Terminal 2 must have battery voltage with the ignition turned on.

3.2 Terminal 3 must have battery voltage with the ignition turned off and the ignition key inserted (radio position).

3.3 Terminal 4 must have battery voltage when the left front wheel is lifted and rotated (speed above 5 km/h).




Check lines or replace control unit for sun roof/radio, if voltage values are not as specified.

4. Check microswitch in roof opening.

Note: The microswitch will prevent running out the lifting elements unintentionally after removing the roof.

4.1 Microswitch must remain in closed position with the roof installed up to the maximum lifting position. The switching point can be identified by a loud "click".

4.2 The roof cannot be lifted when the microswitch is open or a wire is interrupted.




4.3 The operating lever on the micro- switch must move easily.
