B210D-BATTERY VOLTAGE LOW - DDM/PDM

For a complete wiring diagram Refer to Diagrams/Electrical.

- When Monitored:

At all times.

- Set Condition:

Anytime the module senses voltage input below 9.0 volts, this code will set.





Diagnostic Test

1.CHECK ENGINE DTC's

With the scan tool, read ENGINE DTC's

Are there any ENGINE DTC's present?

No

- Go to 2

Yes

- Refer to symptom list for problems related to ENGINE.

2.TEST FOR INTERMITTENT CONDITION

With the scan tool, record and erase DTC's

Start the engine and run for 2 minutes.

With the scan tool, read DTC's 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 BODY VERIFICATION TEST - VER 1. Body Verification Test

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

Disconnect all door module connectors.

Refer to connector pinouts in the wiring for the door module connectors

Test all (A913) Fused B(+) circuits by connecting a 12-volt test light between the Fused B(+) circuit and the Ground circuits 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 BODY VERIFICATION TEST - VER 1. Body Verification Test

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

Turn the ignition on.

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 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 appropriate door module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Test the 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 BODY VERIFICATION TEST - VER 1. Body Verification Test
