Restraints

B210D-BATTERY VOLTAGE LOW





For a complete wiring diagram Refer to Diagrams/Electrical.


- 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 volt.







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 DTC before proceeding.

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

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

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

Measure the voltage between ground and the F100 Fused Ignition Switch Output circuit cavity 32-18 of the ORC 8443-25 Adaptor.
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: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

-
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 *ORC VERIFICATION TEST VER - 1


No


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

- Repair the F100 and F201 Fused Ignition Switch Output circuit for an open or high resistance.
- Perform *ORC VERIFICATION TEST VER - 1.



3. CHECKING STORED OR INTERMITTENT CODES
NOTE: Diagnose and repair all active codes before diagnosing stored codes. Manufacturer Code Charts for a complete list of airbag system diagnostic procedures.

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

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 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


- Diagnose and repair the active DTC(s).

No


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