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

B210D-BATTERY VOLTAGE LOW





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

- When Monitored:
At all times.

- Set Condition:
The module senses voltage input below 9.0 volts for over 15 seconds.





1. CHECK ENGINE DTCs
1. With the scan tool, read ENGINE DTCs.

Are there any ENGINE Charging or Battery DTCs present?

Yes
Perform the appropriate diagnostic procedure. Testing and Inspection
No

- Go To 2

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

Does the scan tool display active: B210D-BATTERY VOLTAGE LOW?

Yes

- Go To 3

No

- The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

3. CHECK THE (A215) FUSED B+ CIRCUIT FOR HIGH RESISTANCE
1. Using the scan tool, read the Battery Voltage of the Door Module.
2. Using the scan tool, read the Battery Voltage of the TIPM (Central Gateway).

Is the voltage within 0.6 volt of each module?

Yes

- Replace the Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. CHECK THE VOLTAGE AT THE DOOR MODULE HARNESS




1. Turn the ignition off.
2. Disconnect the Door Module C3 Harness connector.
3. Using a voltmeter, measure the voltage between the (A215) Fused B(+) circuit and the (Z908) Ground in the Door Module C3 connector.
4. Using a voltmeter, measure the voltage at the battery.

Is the voltage at the module connector within 0.6 volt of battery voltage?

No

- Repair the (A215) Fused B(+) circuit or the (Z908) Ground circuit for high resistance.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Replace the Door Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
