PINPOINT TEST F: THE DRIVER SEAT MODULE (DSM) DOES NOT RESPOND TO THE SCAN TOOL

Normal Operation
The DSM communicates with the scan tool through the UBP communication network. Circuit 1906 (VT) provides the network connection to the DSM. The DSM shares the UBP network with the heating ventilation air conditioning (HVAC) module (if equipped), the vehicle security module (VSM) (if equipped), and the instrument cluster (IC). Voltage for the DSM is provided by circuits 566 (DG) and 956 (OG/LG). Circuits 57 (BK) and 875 (BK/LB) provide ground.

This pinpoint is intended to diagnose the following:
- Fuses
- Wiring, terminals or connectors
- DSM
