Power Liftgate Module (PLGM)

B210D-BATTERY VOLTAGE LOW





For a complete wiring diagram Refer to the Wiring Information.

- When Monitored:
At all times.

- Set Condition:
Whenever the liftgate is activated, if the voltage is below 10.5 volts, within 15 seconds prior to power operation, this code will set.





1. CHECK FOR PCM DTCS

NOTE: Ensure the battery is fully charged and serviceable before proceeding.

1. With the scan tool, read PCM DTCs

Are there any PCM DTCs present?

No

- Go To 2.

Yes

- Diagnose and repair the DTC(s).

2. TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase DTC's
2. Start the engine and run for two minutes.
3. 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 (A115) FUSED B(+) CIRCUIT FOR AN OPEN OR HIGH RESISTANCE





NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery

1. Turn the ignition off.
2. Disconnect the Power Liftgate Module C3 harness connector.
3. Turn the ignition on.
4. Using a 12 volt test light connected to ground, check the (A115) Fused B(+) circuit.

Does the test tight illuminate brightly?

Yes

- Go To 4

No

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

4. CHECK THE (Z910) GROUND CIRCUIT FOR AN OPEN OR HIGH RESISTANCE





NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery

1. Using a 12 volt test light, connect one end to the (A115) Fused B(+) circuit and the other end to the (Z910) Ground in the Liftgate C3 connector.

Does the test tight illuminate brightly?

Yes

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

No

- Repair the (Z910) Ground circuit for an open or high resistance.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.
