Driver Door Module (DDM), (DMFL/R)

B210D-BATTERY VOLTAGE LOW







- When Monitored:
At all times.

- Set Condition:
Anytime the module senses a voltage input below 9.0 volts, this code will set.





1. CHECK POWERTRAIN CONTROL MODULE (PCM) or ENGINE CONTROL MODULE (ECM) DTCs
1. With the scan tool, read the PCM or ECM DTCs.

Are there any Charging or Battery DTCs present?

No

- Go To 2

Yes

- Testing and Inspection and perform the appropriate diagnostic procedure.

2. TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase the DTCs.
2. Start the engine and run for two minutes.
3. With the scan tool, read the DTCs in the Door Module.

Does the scan tool display B210D-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 the BODY VERIFICATION TEST. Body Verification Test.

3. (A215) FUSED B(+) OR (Z921/Z922) GROUND CIRCUITS RESISTED




1. Turn the ignition off.
2. Disconnect the Driver Door Module C3 connector.
3. Test the (A215) Fused B(+) circuits by connecting a 12-volt test light between the Fused B(+) circuit and the (Z921 or Z922) Ground circuits in the door module C3 connector. 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 Driver Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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