Pinpoint Test F: The Global Open Function is Inoperative/Does Not Operate Correctly - MKZ
Refer to Wiring Diagram Set 101, 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 through circuit CPW01 (BN/BU) to the roof opening panel motor. The global open feature does not function when the delayed accessory is active.
The front door window motors use CPW01 (BN/BU) for the global open signal. 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
- Front door window motors
PINPOINT TEST F: THE GLOBAL OPEN FUNCTION IS INOPERATIVE/DOES NOT OPERATE CORRECTLY - MKZ
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 Windows to diagnose the inoperative windows.
-------------------------------------------------
F2 CHECK DRIVER WINDOW MOTOR
- Remove driver door window motor Battery Junction Box (BJB) fuse 34 (30A).
- Operate the power windows using the global open procedure.
- Does the roof opening panel operate correctly?
Yes
INSTALL a new driver window motor. REFER to Windows. TEST the system for normal operation.
No
REINSTALL BJB fuse 34 (30A). GO to F3.
-------------------------------------------------
F3 CHECK PASSENGER WINDOW MOTOR
- Remove passenger door window motor BJB fuse 35 (30A).
- Operate the power windows using the global open procedure.
- Does the roof opening panel operate correctly?
Yes
INSTALL a new passenger window motor. REFER to Windows. TEST the system for normal operation.
No
REINSTALL BJB fuse 35 (30A). GO to F4.
-------------------------------------------------
F4 CHECK CIRCUIT CPW01 (BN/BU) 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-29, 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.
