Driver Door Module Module (DDM)

B210D-BATTERY VOLTAGE LOW



- 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) DTCs.

Are there any Charging or Starting DTCs present?

No

- Go To 2

Yes

- Testing and Inspection 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 active DTCs.

Does the scan tool display B210D-BATTERY VOLTAGE LOW?

Yes

- Go To 3

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
- 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 (A215) 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.
