Occupant Restraint Controller (ORC)

B210E-BATTERY VOLTAGE HIGH

For a complete wiring diagram refer to the Wiring Information. Electrical Diagrams

Theory of Operation

The Occupant Restraint Controller module (ORC) receives power from both a battery and ignition fed input circuit from the Totally Integrated Power Module (TIPM). These circuits power the ORC and the capacitors used to initiate the squib deployment circuits in the event of collision detection.

- When Monitored:
The Occupant Restraint Module (ORC) monitors the battery voltage and ignition continuously.

- Set Condition:
This code is set immediately after the Occupant Restraint Module (ORC) detects that voltage on the battery voltage supply circuit is 17.45 ± 1.45 volts or more for greater than 15 seconds.





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

1. CHECK PCM FOR CHARGING SYSTEM DTCS

NOTE: Ensure the battery is fully charged.

1. Turn the ignition on.
2. With the scan tool, read PCM DTCs.

Are there any Charging System DTCs set in the Powertrain/Engine Control Module?

Yes

- Diagnose and repair the DTC(s).

No

- Go To 2

2. DETERMINE ACTIVE OR STORED DTC
1. With the scan tool, read all active ORC DTCs.

Is the DTC active or stored?

ORC - ACTIVE DTC

- Go To 3

ORC - STORED DTC

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

3. CHECK VOLTAGE TO THE ORC





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.

1. Disconnect the ORC harness connectors.

NOTE: Check connectors - Clean and repair as necessary.

2. Connect the Load Tool ORC 8443-28 Adaptor to the ORC connectors.

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

3. Measure the voltage of the (A27) Fused B+ circuit between the Load Tool ORC 8443-28 Adaptor and ground.

Is the voltage 17.45 ± 1.45 volts or more?

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.

- Repair the (A27) Fused B+ circuit and the (F201) Fused Run/Start Relay Output circuit.
- Perform the RESTRAINTS SYSTEM VERIFICATION TESTRestraints System Verification Test.

No

- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.

- 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.
