Roof Opening Panel

Pinpoint Test F: The Global Open Function is Inoperative/Does Not Operate Correctly

NOTE: The global open feature may be enabled/disabled via scan tool or in some cases modified by the customer following a procedure listed in the vehicle Owner's Literature. For a complete list of available programmable parameters, refer to the Module Configuration and Parameter Chart in Module Configuration [1][2]Initial Inspection and Diagnostic Overview.

Refer to Wiring Diagram Set 101 (Fusion/Milan/MKZ, Fusion Hybrid, Milan Hybrid, MKZ Hybrid), Roof Opening Panel for schematic and connector information. Diagrams By Number

Normal Operation

When the global open feature is activated, the Smart Junction Box (SJB) sends a signal to the roof opening panel motor to place the roof opening panel in the VENT position. The global open feature does not function when the delayed accessory is active. Any interference in the circuit or the window motor may cause the global open feature to not operate correctly.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Roof opening panel motor
- SJB
- Remote Keyless Entry (RKE) transmitters
- Roof opening panel not initialized
- Door window motor


PINPOINT TEST F: THE GLOBAL OPEN FUNCTION IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

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.

-------------------------------------------------
F1 VERIFY THE POWER WINDOWS ARE OPERATIONAL

- Operate the power windows using the global open procedure.
- Do the power windows operate correctly?

Yes
GO to F2.

No
REFER to Glass, Frames and Mechanisms Testing and Inspection to diagnose the inoperative windows.

-------------------------------------------------
F2 CHECK LF DRIVER WINDOW MOTOR

- Remove LF driver 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 LF driver window motor. REFER to Glass, Frames and Mechanisms Window Regulator and Motor - Front Door. TEST the system for normal operation.

No
REINSTALL SJB fuse 1 (30A). GO to F3.

-------------------------------------------------
F3 CHECK RF PASSENGER WINDOW MOTOR

- Remove RF passenger 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 RF passenger window motor. REFER to Glass, Frames and Mechanisms Window Regulator and Motor - Front Door. TEST the system for normal operation.

No
REINSTALL SJB fuse 4 (30A). GO to F4.

-------------------------------------------------
F4 CHECK GLOBAL OPEN CIRCUIT FOR AN OPEN

- Disconnect: Roof Opening Panel Motor C921.
- Disconnect: SJB C2280C.
- Measure the resistance between roof opening panel motor C921-10, circuit CPW01 (BN/BU), harness side and the C2280C-10, circuit CPW01 (BN/BU), harness side.




- Is the resistance less than 5 ohms?

Yes
INSTALL a new roof opening panel motor. REFER to Roof Opening Panel Motor Roof Opening Panel Motor. INITIALIZE the roof opening panel motor. REFER to Roof Opening Panel Motor Initialization Programming and Relearning. TEST the system for normal operation.

No
REPAIR the circuit. INITIALIZE the roof opening panel motor. REFER to Roof Opening Panel Motor Initialization Programming and Relearning. TEST the system for normal operation.
