Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Test
- CHECK FOR ACTIVE DTCS
- With the scan tool, record and erase the DTCs.
- Cycle the ignition off, wait 10 seconds, then cycle the ignition on.
- Operate the liftgate several times.
- With the scan tool, read the Active DTCs.
Does the scan tool display: B195F-12-POWER LIFTGATE CHIME CONTROL - CIRCUIT SHORT TO BATTERY?
Yes
- Go To 2
No
- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and poor pin fit.
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
- CHECK THE (Q94) LIFTGATE CHIME DRIVER CIRCUIT SHORTED TO VOLTAGE
- Cycle the ignition off.
- Disconnect the Power Liftgate Module C2 harness connector.
- Cycle the ignition on.
- Measure the voltage between ground and the (Q94) Liftgate Chime Driver circuit.
Is there any voltage present?
Yes
- Repair the (Q94) Liftgate Chime Driver circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Go To 3
- CHECK THE (Q94) LIFTGATE CHIME DRIVER CIRCUIT FOR AN OPEN
- Cycle the ignition off.
- Disconnect the Power Liftgate Chime harness connector.
- Measure the resistance of the (Q94) Liftgate Chime Driver circuit between the PLGM C2 connector and the Chime connector.
Is the resistance below 1.0 Ohm?
Yes
- Go To 4
No
- Repair the (Q94) Liftgate Chime Driver circuit for an open.
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
- CHECK THE (Z923) GROUND CIRCUIT FOR AN OPEN NOTE:
The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
- Cycle the ignition on.
- Using a 12-volt test light connected to 12-volts, check the (Z923) Ground circuit.
Does the test tight illuminate brightly?
Yes
- Go To 5
No
- Repair the (Z923) Ground circuit for an open.
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
- CHECK THE POWER LIFTGATE CHIME
- Reconnect the Power Liftgate Module C2 harness connector.
- Cycle the ignition on.
- Using the scan tool, actuate the Power Liftgate Chime.
- Measure the voltage between the (Q94) Power Liftgate Chime Driver circuit and the (Z923) Ground circuit in the PLG Chime harness connector.
Does the voltage cycle between 0 and 12 volts?
Yes
- Replace the Power Liftgate Chime in accordance with the Service Information. Refer to CHIME, REMOVAL .
- Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
No
- Replace the Power Liftgate Module in accordance with the Service Information. Refer to MODULE, POWER LIFTGATE (PLGM), REMOVAL .
- Test complete. Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
