Pinpoint Test W : The Tailgate Passive Entry Feature Is Inoperative

WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

W1 CHECK THE LIFTGATE RELEASE SWITCH INPUT
- Close the tailgate.
- Ignition ON.
- Unlock the doors using the door lock control switch.
- Press the tailgate release button located at the rear of the vehicle.
Does the tailgate latch release?

Yes GO to W2

No GO to Pinpoint Test N

W2 CHECK THE RKE (REMOTE KEYLESS ENTRY) OPERATION
- Ignition OFF.
- Close the tailgate.
- Press the tailgate release button twice on a key.
Does the tailgate latch release?

Yes GO to W3

No GO to Pinpoint Test R

W3 CHECK THE KEYLESS ENTRY REAR ANTENNA

Ignition OFF.

Disconnect Keyless Entry Rear Antenna C4817.

Is the resistance between 1 and 3 ohms?

Yes

GO to W4

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

W4 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO VOLTAGE

Disconnect BCM C2280D.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C2280D-30	Courtesy of FORD MOTOR COMPANY	Ground
Refer to C2280D-32	Courtesy of FORD MOTOR COMPANY	Ground

Is any voltage present?

Yes	REPAIR the circuit in question.

GO to W5

W5 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR A SHORT TO GROUND

Ignition OFF.

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C2280D-30	Courtesy of FORD MOTOR COMPANY	Ground
Refer to C2280D-32	Courtesy of FORD MOTOR COMPANY	Ground

Are the resistances greater than 10, 000 ohms?

Yes

GO to W6

No	REPAIR the circuit in question.

W6 CHECK THE KEYLESS ENTRY REAR ANTENNA CIRCUITS FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C2280D-30	Courtesy of FORD MOTOR COMPANY	Refer to C4817-1
Refer to C2280D-32	Courtesy of FORD MOTOR COMPANY	Refer to C4817-2

Are the resistances less than 3 ohms?

Yes

GO to W7

No	REPAIR the circuit in question.

W7 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, Refer to BCM GUIDED ROUTINE TESTING

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.
