Driver's Seat (E38/E39): Diagnosis

The PM-SM communicates with the DISplus or GT-1. The PM-SM monitors the seat motors and circuits as well as it's internal operation. Any detected faults are stored in the PM-SM fault memory and are called up when diagnosing the system with the Fault Symptom diagnostic plan. The PM-SM also provides status display to the DISplus of the input and output control signals as well as component activation.
