Occupant Restraint Controller (ORC)

B2199-17-BATTERY VOLTAGE - CIRCUIT VOLTAGE ABOVE THRESHOLD



Theory of Operation
The Occupant Restraint Controller (ORC) receives fused ignition voltage from the Totally Integrated Power Module (TIPM). The ORC is equipped with two voltage sources the F100 and F201 circuit. These circuits power the ORC and the capacitors used to initiate the squib deployment circuits in the event of collision detection.
- When Monitored:
With the ignition on, the ORC continuously monitors the voltage on the F100 and F201 supply circuits.

- Set Condition:
The ORC will set this Diagnostic Trouble Code (DTC) when the voltage on both supply circuits are above 16 ± 0.5 volts for more than 15 seconds.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.

1.

NOTE: Ensure the battery is fully charged.
CHECK PCM FOR CHARGING SYSTEM DTC
1. Turn the ignition on.
2. With the scan tool, read Powertrain Control Module (PCM) DTCs.

Are there any Charging System DTCs set in the PCM?

Yes

- Testing and Inspection for Charging System diagnostic procedures.

No

- Go To 2

2. VERIFY ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read all ORC DTCs.

Does the scan tool display active B2199-17-BATTERY VOLTAGE - CIRCUIT VOLTAGE ABOVE THRESHOLD DTC?

Yes

- WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

- Replace the ORC.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test.
