Power Seats: Other Saab 9-3 I

POWER SEAT MODULE (PSM)

PSM supplies motors, position sensors and switches with voltage. PSM monitors switches, and when a determined combination of switches have been activated, it performs the appropriate operation. If a seat motor is operating, PSM monitors its voltage consumption and position of seat as determined by position sensors. PSM can store seat settings and fault codes.

Check fuses. Ensure voltage supply to fuses, respective seat switches and motors is intact. Check all connectors, wiring harnesses, and grounds.

Memory power seats are equipped with self-diagnostic capabilities. Faults detected by Power Seat Module (PSM) are stored in memory as Diagnostic Trouble Codes (DTCs). These fault codes can be read using Tech 1 scan tool. See SELF-DIAGNOSTIC SYSTEM .
