Driver Seat Module

The Driver Seat Module (DSM) is located under the driver seat. The DSM provides diagnostic service to the New Generation Star (NGS) tester through the Light Blue/White on the vehicle. In the event the NGS Tester fails to communicate with the DSM, diagnose by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
