Pinpoint Test - Supplemental Restraint System (SRS)

Pinpoint Test AH: DTC U200D:12

Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information. [1][2]Diagrams By Number

Normal Operation
The Occupant Classification System Module (OCSM) monitors each Occupant Classification System (OCS) weight sensor bolt and circuitry for faults. If the OCSM (Occupant Classification System Module) detects unwanted voltage on any weight sensor VREF circuit it will store DTC U200D:12 in memory and send a message to the Restraints Control Module (RCM).
The RCM (Restraints Control Module) will store DTC B00A0:09 in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

- DTC U200D:12 (Control Module Output Power A: Circuit Short to Battery)- If the OCSM (Occupant Classification System Module) detects voltage above 5 volts on any weight sensor VREF circuit, it will set this DTC.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- OCSM (Occupant Classification System Module)
