Roof Opening Panel
Pinpoint Test G: The Global Open Function is Inoperative
Refer to Wiring Diagram Set 101, Roof Opening Panel for schematic and connector information. Diagrams By Number
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 Information Bus.
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 to open the roof opening panel sliding glass to the VENT position. 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
- SJB (Smart Junction Box)
- Roof opening panel motor/module
- Remote Keyless Entry (RKE) transmitters
- Roof opening panel not initialized
- Front door window motors
PINPOINT TEST G : THE GLOBAL OPEN FUNCTION IS INOPERATIVE
NOTICE: 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.
G1 VERIFY GLOBAL OPEN FOR THE POWER WINDOWS IS OPERATIONAL
- Operate the power windows using the global open procedure.
Do the power windows operate correctly?
Yes
GO to G2.
No
REFER to Windows and Glass to diagnose the inoperative windows.
G2 CHECK LF DRIVER WINDOW MOTOR
- Remove LF driver door window motor SJB (Smart Junction Box) 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. TEST the system for normal operation.
No
REINSTALL SJB (Smart Junction Box) fuse 1 (30A). GO to G3.
G3 CHECK RF PASSENGER WINDOW MOTOR
- Remove RF passenger door window motor SJB (Smart Junction Box) 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. TEST the system for normal operation.
No
REINSTALL SJB (Smart Junction Box) fuse 4 (30A). GO to G4.
G4 CHECK CIRCUIT CPW01 (BN/BU) FOR AN OPEN
- Ignition OFF.
- Disconnect: Roof Opening Panel Motor/Module C921.
- Disconnect: SJB (Smart Junction Box) C2280C.
- Measure the resistance between roof opening panel module C921-10, circuit CPW01 (BN/BU), harness side and SJB (Smart Junction Box) C2280C-10, circuit CPW01 (BN/BU), harness side.
Is the resistance less the 5 ohms?
Yes
CHECK the overhead console jumper harness for loose pins or an open in circuit CPW01 (BN/BU) between the roof opening panel switch socket and overhead console C921-14. If the overhead console jumper harness is not
OK, INSTALL a new overhead console jumper harness and TEST the system for normal operation. If the overhead console jumper harness is OK, GO to G5.
No
REPAIR the circuit. TEST the system for normal operation.
G5 CHECK THE ROOF OPENING PANEL MOTOR/MODULE FOR CORRECT OPERATION
- Disconnect all roof opening panel motor/module connectors.
- Check for:
- corrosion.
- bent pins.
- pushed-out pins.
- Connect all roof opening panel motor/module connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
Yes
INSTALL a new roof opening panel motor. REFER to Roof Opening Panel Motor . 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.
