B210D-BATTERY VOLTAGE LOW

For a complete wiring diagram Refer to Section 8W.


  • When Monitored:

    Engine running, during seat motor operation.

  • Set Condition:

    This code is set immediately after the Seat Memory Module receives a low charging system voltage message over the CAN B Bus or detects voltage under 9.5 volts on the (A110) Fused B(+) circuit.


Possible Causes
  
CHARGING SYSTEM VOLTAGE LOW
  
(A110) FUSED B(+) CIRCUIT
  
SEAT MEMORY MODULE
  

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.



Diagnostic Test

1.CHECK PCM FOR CHARGING SYSTEM DTC



Are there any Charging System DTC's set in the Powertrain Control Module?

Yes
  • (Refer to 8 - ELECTRICAL/CHARGING - DIAGNOSIS AND TESTING) for Charging System diagnostic procedures.


No
  • Go To 2
  • Perform POWER SEAT SYSTEM VERIFICATION TEST – VER 1.

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





Does the DTC B210D-BATTERY VOLTAGE LOW reset?

Yes
  • Go To 3


No
  • The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
  • Perform POWER SEAT SYSTEM VERIFICATION TEST – VER 1.

3.CHECK THE VOLTAGE ON THE (A110) FUSED B(+) CIRCUIT




NOTE: Check connectors - Clean and repair as necessary.





Is the voltage at the MSM connector the same as measured at the battery?

Yes
  • Replace the Memory Seat Module in accordance with the service information.
  • Perform POWER SEAT SYSTEM VERIFICATION TEST – VER 1.


No
  • Repair the (A110) Fused B(+) circuit as necessary.
  • Perform POWER SEAT SYSTEM VERIFICATION TEST – VER 1.
