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 for over 15 seconds, this code will set.





Diagnostic Test

1.CHECK ENGINE DTC's

NOTE: Ensure the battery is fully charged before proceeding.

With the scan tool, read ENGINE DTC's

Are there any BATTERY OR CHARGING SYSTEM DTC's?

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.

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.(A937) FUSED B(+) CIRCUIT RESISTED





NOTE: The graphic shows the Driver Door Module. The Passenger Door Module is similar.

NOTE: The graphic shows only one Fused B(+) circuit. The JS vehicle also has a (A937) Fused B(+) circuit in cavity 7. Check both cavities 4 and 7.

Disconnect the Door Module C1 connector

Test for a resisted (A937) Fused B(+) circuit by connecting a 12-volt test light between the (A937) Fused B(+) circuit and the (Z- - -) 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 BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Test the (A937) Fused B(+) and the (Z- - -) Ground circuits to determine which one has the high resistance. Repair the (A937) Fused B(+) circuit or the (Z- - -) Ground circuit for high resistance.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
