B210D-BATTERY VOLTAGE LOW
For a complete wiring diagram Refer to Diagrams/Electrical.
- When Monitored:
Engine running.
- Set Condition:
This code is set immediately after the Door Module detects voltage under 11.3 volts on the (A913) Fused B(+) circuit.
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.
Diagnostic Test
1.CHECK PCM FOR CHARGING SYSTEM DTC
With the scan tool, read Powertrain Control Module DTC's.
Are there any Charging System DTC's set in the Powertrain Control Module?
Yes
- Refer to Charging System testing for Charging System diagnostic procedures.
No
- Go To 2
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
2.VERIFY THAT DTC B210D-BATTERY VOLTAGE LOW IS ACTIVE
With the scan tool, record and erase DTC's
Turn the ignition switch to the OFF position then start the engine and let run for one minute.
With the scan tool, read DTC's.
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 BODY VERIFICATION TEST - VER 1. Body Verification Test
3.CHECK THE VOLTAGE ON THE (A913) FUSED B(+) CIRCUIT
Disconnect the appropriate Door Module C4 connector.
NOTE: Check connectors - Clean and repair as necessary.
Start the engine and let idle.
Measure the voltage on the (A913) Fused B(+) circuit at the Door Module C4 connector and compare to voltage at the vehicle battery.
Is the voltage at the Door Module C4 connector the same as measured at the battery?
Yes
- Replace the Driver/Passenger Door Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
No
- Repair the (A913) Fused B(+) circuit as necessary.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
