B210D-BATTERY VOLTAGE LOW - DOOR MODULE

For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

At all times.

- Set Condition:

Anytime the module senses voltage input below 9.5 volts, this code will set.





Diagnostic Test

1.CHECK ENGINE DTC's

With the scan tool, read ENGINE DTC's

Are there any ENGINE DTC's present?

No

- Go To 2

Yes

- Refer to symptom list for problems related to ENGINE.

2.TEST FOR INTERMITTENT CONDITION

With the scan tool, record and erase DTC's

Start the engine and run for two minutes.

Cycle the ignition from on to off three times.

Turn the ignition on.

With the scan tool, read DTC's.

Does the scan tool display BATTERY VOLTAGE LOW?

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.(A215) FUSED B(+) OR GROUND CIRCUITS RESISTED

Disconnect all door module connectors.

Refer to connector pinouts in the wiring section for the door module connectors

Test all (A215) Fused B(+) circuits by connecting a 12-volt test light between the Fused B(+) circuit and the Z940 Ground circuits in the door module connectors. The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

Does the test light illuminate brightly?

Yes

- Replace the Door Module.

No

- Test the Fused B(+) and the Ground circuits to determine which one has the high resistance. Repair the circuit for high resistance.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
