Step 1: Inspect the Liftgate Mechanism

Visual Inspection:
- Check for any visible damage or obstruction in the liftgate area.
- Ensure the liftgate is not blocked by any debris.
Check for Electrical Issues:
- Using the OBD-II scanner, check for any stored fault codes related to the liftgate system.
- If codes are present, note them for further investigation.

Step 2: Test the Key Fob and Switches

Key Fob Test:
- Replace the battery in the key fob if it has not been changed recently.
- Test the liftgate operation using the key fob; if it works, the issue may be with the internal switch.
Switch Test:
- Use a multimeter to test the liftgate switch inside the vehicle for continuity.
- If the switch is faulty, replace it.

Step 3: Inspect Electrical Connections

Check Wiring:
- Inspect the wiring harness connected to the liftgate for any signs of damage or corrosion.
- Clean any corroded connectors using electrical contact cleaner.
Power Supply Test:
- With the multimeter, check for voltage at the liftgate motor connector when the liftgate switch is activated.
- If no voltage is present, trace back to the fuse box to check for blown fuses (typically fuse #45 or #47 for the liftgate).

Repair Instructions
