Passenger Door Module (PDM), (DMFR)
B210C-16-BATTERY VOLTAGE INPUT - CIRCUIT VOLTAGE BELOW THRESHOLD
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
At all times.
- Set Condition:
Anytime the module senses voltage input below 8.0 Volts for more than four seconds, this code will set.
1. CHECK ENGINE DTCs
1. Using the scan tool, read the active Powertrain Control Module DTCs.
Are there any PCM Charging or Battery DTCs present?
Yes
- Testing and Inspection and perform the appropriate diagnostic procedure.
No
- Go To 2
2. TEST FOR INTERMITTENT CONDITION
1. Using the scan tool, record and erase the DTCs.
2. Start the engine and run for two minutes.
3. Using the scan tool, read the active DTCs in the Door Module.
Does the scan tool display B210C-16-BATTERY VOLTAGE INPUT - CIRCUIT VOLTAGE BELOW THRESHOLD?
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. (A214) FUSED B(+) OR (Z919) GROUND CIRCUITS RESISTED
1. Turn the ignition off.
2. Disconnect the Passenger Door Module C3 connector.
3. Turn the ignition on.
4. Test the (A214) Fused B(+) circuits by connecting a 12-volt test light between the Fused B(+) circuit and the (Z919) 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. Door Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Test the (A214) Fused B(+) and the (Z919) Ground circuits to determine which one has the high resistance. Repair the necessary circuit for high resistance.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
