B210D-BATTERY VOLTAGE LOW

For a complete wiring diagram Refer to Section 8W.






  • 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.


Possible Causes
  
OCM (A27) FUSED B(+) CIRCUIT OPEN
  
VEHICLE CHARGING SYSTEM
  
OCCUPANT CLASSIFICATION MODULE (ORC)
  



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.





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

Yes
  • Go To 2


No
  • Go To 3

2.CHECK VOLTAGE OF OCM (A27) FUSED B(+) CIRCUIT.

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



WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.




Is the voltage above 6.0 volts circuit?

Yes
  • Replace the OCM in accordance with the service information.
  • Perform *OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST


No
  • Repair the (A27) Fused B(+) circuit for an open or high resistance.
  • Perform *OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST.

3.CHECKING STORED OR INTERMITTENT CODES

NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to the Table of Contents in this Section for a complete list of airbag system diagnostic procedures.



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




WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.



Does the scan tool display any ACTIVE DTCs?

Yes
  • Select the appropriate diagnostic procedure from the Table of Contents in this section.


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