Driver Door Module (DDM)

B210D-BATTERY VOLTAGE LOW

For a complete wiring diagram, refer to the wiring information Electrical Diagrams.

- When Monitored:
At all times.

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





1. CHECK ENGINE DTCs
1. With the scan tool, read active Powertrain Control Module (PCM) or Engine Control Module (ECM) DTCs.

Are there any Charging or Starting DTCs present?

No

- Go To 2

Yes

- Perform the appropriate diagnostic procedure.
- For gas engine applications, Testing and Inspection.

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 active DTCs.

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 (Z913) GROUND CIRCUITS RESISTED




1. Disconnect the Driver Door Module C3 connector.
2. Connect a 12-volt test light between the Fused B(+) circuit and the (Z913) Ground circuit in the door module 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 circuit to determine which one has the high resistance. Repair the circuit for high resistance.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
