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:
This Diagnostic Trouble Code (DTC) sets anytime the module senses voltage input below nine volts for more than 15 seconds.





1. CHECK ENGINE DTCs

NOTE: Make sure the battery is fully charged before proceeding.

1. With the scan tool, read ENGINE DTCs

Are there any Battery or Charging system DTCs?

No

- Go To 2

Yes

- Perform the appropriate Powertrain diagnostic procedure. Testing and Inspection.

2. TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase DTCs.
2. Start the engine and run for two minutes.
3. With the scan tool, read 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(+) CIRCUIT RESISTED




1. Disconnect the Door Module C1 harness connector
2. Test for a resisted (A215) Fused B(+) circuit by connecting a 12-volt test light between the (A215) Fused B(+) circuit and the (Z940) 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 Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Test the (A215) Fused B(+) and the (Z940) Ground circuits to determine which one has the high resistance. Repair the (A215) Fused B(+) circuit or the (Z940) Ground circuit for high resistance.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
