Power Liftgate

B210D-BATTERY VOLTAGE LOW - PLG

For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
When power opening or closing operations are not occurring.

- Set Condition:
The Power Liftgate Module senses voltage input below 9.5 volts when a power opening or closing operation is not occurring.





Diagnostic Test

1. CHECK ENGINE DTC's
NOTE: Ensure the battery is fully charged and serviceable before proceeding.

With the scan tool, read ENGINE DTC's
Are there any ENGINE DTC's present?

No

- Go To 3

Yes

- Diagnose and repair the DTC(s).

2. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase DTC's
Start the engine and run for two 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. CHECK THE Z125 GROUND CIRCUIT FOR AN OPEN
Turn the ignition off
Disconnect the Power Liftgate Module C3 harness connector.
Measure the resistance between ground and the (Z125) Ground circuit in the Power Liftgate Module C3 harness connector.
Is the resistance below 100 ohms?

Yes

- Go To 4

No

- Repair the (Z125) Ground circuit for an open.
- PERFORM BODY VERIFICATION TEST - VER 1. Body Verification Test

4. (A115) FUSED B+ CIRCUIT RESISTED
Using the scan tool, read the Battery Voltage of the Power Liftgate Module.
Using the scan tool, read the Battery Voltage of the FCM (Central Gateway).
Is the voltage within 0.2 volt of each module?

Yes

- Replace the Power Liftgate Module.
- PERFORM BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Repair the (A115) Fused B+ circuit for high resistance.
- PERFORM BODY VERIFICATION TEST - VER 1. Body Verification Test
