Pinpoint Test - Supplemental Restraint System (SRS)
Pinpoint Test AI: DTCs U3003:16 and U3003:17
Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information. [1][2]Diagrams By Number
NOTE: DTCs B1317, B1318, B1676 U3003:16 and U3003:17 can be set if the vehicle has been recently jump started, the battery has been recently charged or the battery has been discharged. The battery may become discharged due to excessive load(s) on the charging system from aftermarket accessories or if the battery has been left unattended with the accessories on.
Normal Operation - Restraints Control Module (RCM)
The Restraints Control Module (RCM) continuously monitors the input voltage for correct operation. If the RCM (Restraints Control Module) detects input voltage below 9.5 volts, it will store DTC U3003:16 in memory. If the RCM (Restraints Control Module) detects input voltage of 20 volts, it will store DTC U3003:17 in memory. If the RCM (Restraints Control Module) sets DTC U3003:16 or U3003:17, it will send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
Normal Operation - Occupant Classification System Module (OCSM)
The Occupant Classification System Module (OCSM) continuously monitors the input voltage for correct operation. If the OCSM (Occupant Classification System Module) detects input voltage below 8 volts, it will store DTC U3003:16 in memory. If the OCSM (Occupant Classification System Module) detects input voltage above 17.2 volts, it will store DTC U3003:17 in memory. If the OCSM (Occupant Classification System Module) sets DTC U3003:16 or U3003:17, it will send a fault message to the RCM (Restraints Control Module). The RCM (Restraints Control Module) will then send a message to the IPC (Instrument Panel Cluster) to illuminate the air bag warning indicator.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- RCM (Restraints Control Module)
- OCSM (Occupant Classification System Module)
