Occupant Restraint Controller (ORC)

B210D-BATTERY VOLTAGE LOW





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

- When Monitored:
While the Occupant Classification Module (OCM) CAN bus ignition status received is RUN or signal not available, the module checks the (A417) Fused B(+) circuit voltage input range.

- Set Condition:
If the OCM detects that the battery voltage is less than or equal to 6.25 volts ± 0.25 of a volt.





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

NOTE: Make sure the battery is fully charged.

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

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

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

Yes

- Go To 2

No

- Go To 3

2. CHECK VOLTAGE OF ORC CIRCUIT.

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.
2. Connect the Load Tool ORC Adapter 8443-25 to the ORC connectors.

WARNING: Turn the ignition on, then reconnect the 12-volt battery. 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 F100 Fused Ignition Switch Output circuit cavity 32-18 of the ORC 8443-25 Adaptor.
4. Measure the voltage between ground and the F201 Fused Ignition Switch Output circuit cavity 32-17 of the ORC 8443-25 Adaptor.

Is the voltage above 6.25 volts circuit 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 is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment and serious or fatal injury.

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

No

- 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 F100 and F201 Fused Ignition Switch Output circuit for an open or high resistance.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.

3. CHECKING STORED OR INTERMITTENT CODES

NOTE: Diagnose and repair all active codes before diagnosing stored codes.

1. With the scan tool, record and erase all Airbag System Module DTC.

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.

2. Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chafed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.
3. Reconnect all disconnected components and harness 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.

Does the scan tool display any ACTIVE DTC?

Yes

- Perform the appropriate diagnostic procedure. Testing and Inspection

No

- No problem found at this time. Erase all codes before returning vehicle to customer.
