Restraints

B210D-BATTERY VOLTAGE LOW





For a complete wiring diagram Consult Diagrams/Electrical.

- 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.





Diagnostic Test

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.

Turn the ignition on.
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

- Go To 3

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




WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.

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

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

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

- Replace the ORC.
- Perform *ORC VERIFICATION TEST - VER 1. Verification Tests

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 *ORC VERIFICATION TEST - VER 1. Verification Tests

3. CHECKING STORED OR INTERMITTENT CODES
NOTE: Diagnose and repair all active codes before diagnosing stored codes.

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

WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

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.
Reconnect all disconnected components and harness connectors.

WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

Does the scan tool display any ACTIVE DTCs?

Yes

- Select the appropriate diagnostic procedure.

No

- No problem found at this time. Perform *ORC VERIFICATION TEST - VER 1. Verification Tests. Erase all codes before returning vehicle to customer.
