Important: Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

The liftgate module supplies power and ground to operate the liftgate clutch, which is part of the clutch/motor assembly. Upon receiving a liftgate request, the liftgate module supplies voltage to the clutch via the clutch control circuit. The clutch is grounded via the clutch ground circuit. With the clutch energized, the motor output is mechanically connected to the liftgate and power liftgate operation is allowed.

A liftgate open or close function is attempted.

The following failures to either the open control or the close control circuit will set the DTC:

The liftgate operation is suspended for the ignition cycle.

1. Attempt to open the liftgate. The liftgate should smoothly open.
2. Attempt to close the liftgate. The liftgate should smoothly close.

1. Ignition OFF, disconnect the liftgate module harness connector containing the liftgate clutch control circuits.
2. With a DMM, measure for approximately 10 ohm of resistance between the clutch engage circuit and the clutch ground circuit.

⇒	If resistance does not equal 10 ohm, test both circuits for a short to voltage, open or high resistance. If the circuit/connections test normal, replace the liftgate motor/clutch assembly.

3. Test or replace the liftgate module.

Important: Always perform the Diagnostic Repair Verification after completing the diagnostic procedure.
