Power Liftgate Module (PLGM)

B210D-BATTERY VOLTAGE LOW





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

- When Monitored:
When a power opening or closing operation is not occurring.

- Set Condition:
Anytime the Power Liftgate Module senses voltage input below 9.5 volts when a power opening or closing operation is not occurring, this code will set.





1. CHECK ENGINE DTC's

NOTE: Ensure the battery is fully charged before proceeding.

1. With the scan tool, read ENGINE DTC's

Are there any BATTERY OR CHARGING SYSTEM DTC's?

No

- Go to 2

Yes

- Refer to appropriate diagnostic procedure.

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

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. CHECK THE (A115) FUSED B(+) AND THE (Z125) GROUND CIRCUITS FOR AN OPEN OR HIGH RESISTANCE




1. Disconnect the Power Liftgate Module C3 harness connector
2. Test for an open or high resistance on the (A115) Fused B(+) circuit by connecting a 12-volt test light between the (A115) Fused B(+) circuit and the (Z125) Ground circuit in the Power Liftgate Module harness C3 harness 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 Power Liftgate Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the (A115) Fused B(+) or the (Z125) Ground circuit for an open or high resistance.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
