Passenger Door Module (PDM)

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 POWERTRAIN CONTROL MODULE (PCM) or ENGINE CONTROL MODULE (ECM) DTCs
1. With the scan tool, read the PCM or ECM DTCs.

Are there any Engine Charging or Starting System DTCs present?

No

- Go To 2

Yes

- Refer toTesting and Inspection for gas engine applications and perform the appropriate diagnostic procedure.

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 in the Door Module.

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. (A913) FUSED B(+) OR GROUND CIRCUITS RESISTED




1. Turn the ignition off.
2. Disconnect all Passenger Door Module connectors.
3. The (A913) Fused B(+) is in the C2 connector (Non-Memory) and in the C4 connector (With Memory).
4. Test the (A913) Fused B(+) circuits by connecting a 12-volt test light between the (A913) Fused B(+) circuit and the (Z911) Ground circuit in the door module connectors. 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

- Go To 4

No

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

4. (F881) FUSED ACCESSORY DELAY OUTPUT OR GROUND CIRCUIT RESISTED




1. Turn the ignition on.
2. Test the (F881) Fused Accessory Delay Relay Output circuit by connecting a 12-volt test light between the (F881) Fused Accessory Delay Output circuit and the Ground circuit in the Passenger Door Module C1 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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Test the (F881) Fused Accessory Delay Relay Output circuit 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.
