Pinpoint Test G: The Global Open Function Is Inoperative - MKX
WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 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.
NOTE:
Both the power sliding glass motor and the power shade motor must be the same build level. For information on the build level of the motor, refer to the REMOVAL AND INSTALLATION of that motor.
NOTE:
The jumper wiring harness is different on the older level (black and silver) and the newer level (blue and white) motors. They are not interchangeable. Make sure to match the jumper wiring harness with the correct level of motor.
- 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 LF DRIVER WINDOW MOTOR
- Remove LF driver door window motor SJB fuse 4 (30A).
- Operate the power windows using the global open procedure.
- Does the roof opening panel operate correctly?
- Yes: INSTALL a new LF driver window motor. REFER to GLASS, FRAMES AND MECHANISMS . TEST the system for normal operation.
- No: REINSTALL SJB fuse 4 (30A). GO to G3 .
- G3 CHECK RF PASSENGER WINDOW MOTOR
- Remove RF passenger door window motor SJB fuse 1 (30A).
- Operate the power windows using the global open procedure.
- Does the roof opening panel operate correctly?
- Yes: INSTALL a new RF passenger window motor. REFER to GLASS, FRAMES AND MECHANISMS . TEST the system for normal operation.
- No: REINSTALL SJB fuse 1 (30A). GO to G4 .
- G4 CHECK GLOBAL OPEN CIRCUIT FOR AN OPEN
- Disconnect: Roof Opening Panel Motor Assembly C920.
- Disconnect: SJB C2280C.
- Measure the resistance between roof opening panel motor assembly C920-10, circuit VPW01 (GN/BU), harness side and SJB C2280C-10, circuit VPW01 (GN/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 VPW01, component side and the roof opening panel sliding glass wiring harness socket.
- 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.
