Pinpoint Test W: The Liftgate Passive Entry Feature Is Inoperative

W1 CHECK THE RKE (REMOTE KEYLESS ENTRY) OPERATION
- Ignition OFF.
- Close the liftgate.
- Press the liftgate release button twice on a key.
Does the liftgate latch release (manual liftgate) or the liftgate power open (power liftgate)?

Yes GO to W2

No GO to Pinpoint Test R

W2 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 latch release (manual liftgate) or power open (power liftgate)?

Yes	For vehicles with a manual liftgate, GO to W5 For vehicles equipped with a power liftgate, GO to W3

No	For vehicles with a manual liftgate, GO to Pinpoint Test N For vehicles equipped with a power liftgate, REFER to: Body Closures

W3 CHECK THE BCM (BODY CONTROL MODULE) LIFTGATE RELEASE SWITCH STATUS (LFTGATE_R_SW) PID (PARAMETER IDENTIFICATION)
- Using a diagnostic scan tool, view the BCM LFTGATE_R_SW PID while pressing the liftgate release switch.
Does the PID indicate the switch is pressed?

Yes GO to W5

No GO to W4

W4 CHECK THE LIFTGATE RELEASE SWITCH INPUT CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect BCM C2280D.

Disconnect Exterior Liftgate Release Switch C4216.

Measure:

Is the resistance less than 3 ohms?

Yes

GO to W9

No	REPAIR the circuit.

W5 CHECK THE KEYLESS ENTRY REAR ANTENNA

Ignition OFF.

Disconnect Keyless Entry Rear Antenna C4321.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the resistance between 1 and 3 ohms?

Yes

GO to W6

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

W6 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO VOLTAGE

Disconnect BCM C2280E.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is any voltage present?

Yes	REPAIR the circuit in question.

GO to W7

W7 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO GROUND

Ignition OFF.

Measure:

Positive Lead	Measurement / Action	Negative Lead

C2280E-15	Courtesy of FORD MOTOR COMPANY	Ground

Are the resistances greater than 10, 000 ohms?

Yes

GO to W8

No	REPAIR the circuit in question.

W8 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead
C2280E-16	Courtesy of FORD MOTOR COMPANY	C4817-1
C2280E-15	Courtesy of FORD MOTOR COMPANY	C4817-2

Are the resistances less than 3 ohms?

Yes

GO to W9

No	REPAIR the circuit in question.

W9 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 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, A guided routine is not applicable for this vehicle and market. Replace the component that was faulted through 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.
