Occupant Restraint Controller (ORC)

B210D-BATTERY VOLTAGE LOW





For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation
The Occupant Restraint Controller module (ORC) receives power from both a battery and ignition fed input circuit from the Power Integrated Module. These circuits power the ORC and the capacitors used to initiate the squib deployment circuits in the event of collision detection.
- When Monitored:
While the Occupant Restraint Controller (ORC) CAN bus ignition status received is RUN or Signal Not Available (SNA), the module checks the (F100) Fused Run relay Output circuit and (F201) Fused Ignition Switch Output (Run/Start) circuit voltage input range.

- Set Condition:
The code will be set active if the ORC detects that the battery voltage is less than or equal to 6.25 ± 0.25 volts on both circuits.





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

1. VERIFY THAT DTC B210D-BATTERY VOLTAGE LOW IS ACTIVE

NOTE: Ensure the battery is fully charged.

NOTE: Troubleshoot any PCM charging/cranking DTCs before proceeding.

1. Turn the ignition on.
2. With the scan tool, read the Occupant restraint Controller (ORC) DTCs.

Does the scan tool display active: B210D-BATTERY VOLTAGE LOW?

Yes

- Go To 2

No

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

2. CHECK VOLTAGE OF ORC (F100) FUSED RUN RELAY OUTPUT AND (F201) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUITS.





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 connectors.

NOTE: Check the connectors - Clean and repair as necessary.

2. Connect the SRS Load Tool 8443-24 Adaptor to the ORC C2 connector.

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 between Ground and the (F201) Fused Ignition Switch Output (Run-Start) circuit at the 8443-24 C2-29.
4. Measure the voltage between Ground and the (F100) Fused Run Relay Output circuit at the 8443-24 C2-30.

Is the voltage above 6.5 volts on both circuits?

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.

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

- Replace the ORC.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.

No

- Repair the (F100) Fused Run Relay Output and/or (F201) Fused Ignition Switch Output (Run-Start) circuits for an open or high resistance.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.
