The sun roof motor is connected (1) to the Sun Roof Module (SRM), which regulates current to the motor. Nominal system voltage is 12 V. Maximum top load during normal operation is 5 A. The motor drives a gear wheel (2), which engages the drive cables and causes them to rotate. The gear wheel has a maximum torque of 2.0 Nm and the motor has thermal overload protection. The motor is mounted with screws in the three mounting points (3) in the sun roof frame.

CAUTION:

In the event of mechanical blockage, which is normally prevented by the Sun Roof Module (SRM), the motor can produce a maximum torque of 6.8 Nm. This can damage drive wheels and cables. If the sun roof has been blocked, all sun roof components must be checked and, if necessary, replaced before recalibration.
