NOTE: Make sure the power liftgate is enabled from the message center.
- Ignition ON.
- Unlock the doors from the door lock control switch.
- Press the exterior liftgate release switch on the liftgate.
Does the power liftgate open?

Yes GO to J2

No GO to Pinpoint Test C

J2 CHECK THE LIFTGATE PASSIVE ENTRY OPERATION

Is the resistance less than 3 ohms?

Yes

GO to J11

No	REPAIR the circuit.

J9 CHECK THE HANDS-FREE LIFTGATE ACTUATION LOWER SENSOR
- INSTALL a new hands-free liftgate actuation lower sensor. REFER to: Hands-Free Liftgate Actuation Lower Sensor .
- Check the operation of the hands-free liftgate actuation.
Does the hands-free liftgate actuation operate?

Yes The system is operating correctly. The concern was caused by the hands-free liftgate actuation lower sensor.

No GO to J10

J10 CHECK THE HANDS-FREE LIFTGATE ACTUATION UPPER SENSOR
- INSTALL a new hands-free liftgate actuation upper sensor. REFER to: Hands-Free Liftgate Actuation Upper Sensor .
- Check the operation of the hands-free liftgate actuation.
Does the hands-free liftgate actuation operate?

Yes The system is operating correctly. The concern was caused by the hands-free liftgate actuation upper sensor.

No INSTALL a new hands-free liftgate actuation module. REFER to: Hands-Free Liftgate Actuation Module .

J11 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all BCM connectors.

Repair:
- corrosion (install new connectors or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect all the BCM connectors and make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes

CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, BCM guided routine is not applicable for this vehicle and market. Replace the component that was faulted through service information diagnosis.

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
