Pinpoint Test I: The Global Open/Closing Function is Inoperative

Refer to Wiring Diagram Set 101, Roof Opening Panel for schematic and connector information. Diagrams By Number

Normal Operation

When the global open/close feature is activated, the Smart Junction Box (SJB) sends a signal through circuit VPW01 (GN/BU) to the front sliding glass 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.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- SJB
- Front sliding glass motor



PINPOINT TEST I: THE GLOBAL OPEN/CLOSING FUNCTION IS INOPERATIVE

-------------------------------------------------
I1 VERIFY GLOBAL OPEN/CLOSE FOR THE POWER WINDOWS IS OPERATIONAL


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

Yes
GO to I2.

No
REFER to Windows to diagnose the inoperative windows.

-------------------------------------------------
I2 CHECK CIRCUIT CPW01 (BN/BU) FOR AN OPEN


- Ignition OFF.
- Disconnect: Roof Opening Panel Module C921.
- Disconnect: SJB C2280C.
- Measure the resistance between roof opening panel module C921-14, circuit CPW01 (BN/BU), harness side and SJB C2280C-10, circuit CPW01 (BN/BU), harness side.




- Is the resistance less than 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 I3.

No
REPAIR the circuit. TEST the system for normal operation.

-------------------------------------------------
I3 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 front sliding glass panel motor. REFER to Roof Opening Panel Motor - Sliding Front Panel Roof Opening Panel Motor - Sliding Front Panel. 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.
