Passenger Door Module (PDM), (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 ENGINE DTCs
1. With the scan tool, read ENGINE DTCs

Are there any ENGINE Charging or Battery DTCs present?

No

- Go To 2

Yes

- Testing and Inspection Perform the appropriate diagnostic procedures.

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 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. (A214) FUSED B(+) OR (Z921/Z922) GROUND CIRCUITS RESISTED





NOTE: The graphic shows Driver side, Passenger side is similar.

1. Turn the ignition off.
2. Disconnect the Passenger Door Module C3 connector.
3. Test the (A214) Fused B(+) circuits by connecting a 12-volt test light between the (A214) 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 Passenger 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.
