Pinpoint Test V : The Power Liftgate Passive Entry Feature Is Inoperative

V1 CHECK THE RKE (REMOTE KEYLESS ENTRY) OPERATION
- Ignition OFF.
- Close the liftgate.
- Press the liftgate release button twice on a valid programmed passive key.
Does the liftgate power open?

Yes GO to V2

No GO to Pinpoint Test Q

V2 CHECK THE LIFTGATE RELEASE SWITCH INPUT
- Close the liftgate.
- Ignition ON.
- Unlock the doors using the door lock control switch.
- Press the liftgate release button located at the rear of the vehicle.
Does the liftgate power open?

Yes GO to V3

No REFER to: Body Closures .

Is the resistance between 1 and 3 ohms?

Yes

GO to V4

No	INSTALL a new keyless entry rear antenna. REFER to: Keyless Entry Rear Antenna .

Are the resistances greater than 10, 000 ohms?

Yes

GO to V6

No	REPAIR the circuit in question.

V6 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR AN OPEN

Measure:

C2280D-15	Courtesy of FORD MOTOR COMPANY	C4332-2

Are the resistances less than 3 ohms?

Yes

GO to V7

No	REPAIR the circuit in question.

V7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all the 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 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 service articles: TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles 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.
