Pinpoint Test G: The Global Open Function Is Inoperative - MKX

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

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

NOTE: One-touch open must be operational for the global open function to operate correctly. Make sure the one-touch open is operational before proceeding with this diagnostic.

G1 VERIFY THE POWER WINDOWS ARE OPERATIONAL
- Operate the power windows using the global open procedure.
Do the power windows operate correctly?
- Yes : GO to G2.
- No : REFER to GLASS, FRAMES AND MECHANISMS to diagnose the inoperative windows.
G2 CHECK LH FRONT WINDOW MOTOR
- Remove LH front door window motor BCM fuse 1 (30A).
- Operate the power windows using the global open procedure.
Does the roof opening panel operate correctly?
- Yes : INSTALL a new LH front window motor. REFER to GLASS, FRAMES AND MECHANISMS . TEST the system for normal operation.
- No : REINSTALL BCM fuse 1 (30A). GO to G3.
G3 CHECK RH FRONT WINDOW MOTOR
- Remove RH front door window motor BCM fuse 3 (30A).
- Operate the power windows using the global open procedure.
Does the roof opening panel operate correctly?
- Yes : INSTALL a new RH front window motor. REFER to GLASS, FRAMES AND MECHANISMS . TEST the system for normal operation.
- No : REINSTALL BCM fuse 3 (30A). GO to G4.
G4 CHECK GLOBAL OPEN CIRCUIT FOR AN OPEN
- Disconnect: Roof Opening Panel Motor Assembly C920.
- Disconnect: BCM C2280C.
- Measure the resistance between BCM C2280C-25 , circuit CPW01 (BN/BU), harness side and roof opening panel motor assembly C920-10 , circuit CPW01 (BN/BU) harness side.

Is the resistance less than 5 ohms?
- Yes : GO to G5.
- No : REPAIR the circuit. INITIALIZE the roof opening panel motor. REFER to ROOF OPENING PANEL MOTOR INITIALIZATION . TEST the system for normal operation.
G5 CHECK THE ROOF OPENING PANEL MOTOR WIRING HARNESS
- Check the roof opening panel motor wiring harness for loose pins, an open or a short between roof opening panel motor assembly C920-10 , circuit CPW01, component side and the roof opening panel sliding glass motor harness connector.
Is the roof opening panel motor wiring harness OK?
- Yes : GO to G6.
- No : INSTALL a new roof opening panel motor wiring harness. REFER to ROOF OPENING PANEL MOTOR WIRING HARNESS . INITIALIZE the roof opening panel motor. REFER to ROOF OPENING PANEL MOTOR INITIALIZATION . TEST the system for normal operation.
G6 CHECK THE ROOF OPENING PANEL MOTORS FOR CORRECT OPERATION
- Disconnect all roof opening panel motor connectors.
- Check for:
  - corrosion.
  - bent or pushed-out pins.
- Connect all roof opening panel motor connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
- Yes : For an inoperative roof opening sliding glass panel motor, INSTALL a new roof opening sliding glass panel motor. REFER to ROOF OPENING PANEL MOTOR - SLIDING FRONT PANEL . For an inoperative roof opening panel shade motor, INSTALL a new roof opening panel shade motor. REFER to ROOF OPENING PANEL MOTOR - SHADE . INITIALIZE the roof opening panel motor. REFER to ROOF OPENING PANEL MOTOR INITIALIZATION . TEST the system for normal operation.
- No : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
