Brief description, PSM: Motors

WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

The motors are controlled by the switches in the switch unit and are monitored by the PSM. When the motors are running, the control module detects the pulses from the Hall sensors, which are used for programming. To change the direction of rotation of the motors, the polarity of the motor is reversed.
