Roof Opening Panel

Pinpoint Test F: The Roof Opening Panel Does Not Open or Close - Front Sliding Glass Panel

Normal Operation

The front sliding glass panel motor receives voltage from the accessory delay relay through circuit CBP41 (BU) when the key is in the ACC or RUN position and voltage at all times through circuit SBB08 (VT/RD). The front sliding glass panel motor is grounded through circuit GD133 (BK). The front sliding glass panel motor provides ground to the roof opening panel switches through circuit CPR40 (YE/OG). When the roof opening panel slide switch is pulled, a ground signal is sent to the front sliding glass panel motor through circuit CPR31 (VT/BN) which causes the sliding glass panel to close. When the roof opening panel slide switch is pressed, a ground signal is sent to the front sliding glass panel motor through circuit CPR39 (VT/WH), which causes the sliding glass panel to open.

This pinpoint test is intended to diagnose the following:

- Fuse(s)

- Front sliding glass panel motor not initialized

- Wiring, terminals or connectors

- Roof opening panel switch

- Front sliding glass panel motor

PINPOINT TEST F : THE ROOF OPENING PANEL DOES NOT OPEN OR CLOSE - FRONT SLIDING GLASS PANEL

F1 CHECK THE POWER WINDOW OPERATION

- Ignition ON.

Do the power windows operate?

Yes
GO to F2.

No
REFER to Windows and Glass to diagnose the accessory delay relay circuit.

F2 CHECK THE FRONT SLIDING GLASS PANEL MOTOR FOR INITIALIZATION

- Carry out the front sliding glass panel motor initialization procedure. Refer to Roof Opening Panel Motor Initialization .

Is the concern still present?

Yes
GO to F3.

No
The system is operating normally at this time. The front sliding glass panel motor was not initialized.

F3 CHECK THE ROOF OPENING PANEL SWITCH

- Ignition OFF.

- Disconnect: Roof Opening Panel Switch C912.

- Carry out the Roof Opening Panel Switch Component Test.

Is the roof opening panel switch OK?

Yes
GO to F4.

No
INSTALL a new roof opening panel switch. TEST the system for normal operation.

F4 CHECK VOLTAGE TO THE FRONT SLIDING GLASS PANEL MOTOR

- Ignition OFF.

- Disconnect: Roof Opening Panel Module C921.

- Ignition ON.

- Measure the voltage between roof opening panel module C921-1, circuit SBB08 (VT/RD), harness side and ground; and between roof opening panel module C921-2, circuit CBP41 (BU), harness side and ground.





Are the voltages greater than 10 volts?

Yes
GO to F5.

No
VERIFY Battery Junction Box (BJB) fuse 8 (30A) and Smart Junction Box (SJB) fuse 41 (15A) are OK. If OK, REPAIR the circuit. TEST the system for normal operation.

If not OK, Refer to the Wiring Diagrams to identify the possible causes of the circuit short. REPAIR the circuit. TEST the system for normal operation. Electrical Diagrams

F5 CHECK THE FRONT SLIDING GLASS PANEL MOTOR GROUND

- Ignition OFF.

- Measure the resistance between roof opening panel module C921-4, circuit GD133 (BK), harness side and ground.





Is the resistance less than 5 ohms?

Yes
GO to F6.

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

F6 CHECK CIRCUIT CPR39 (VT/WH) FOR AN OPEN OR SHORT TO GROUND

- Measure the resistance between roof opening panel switch C912-6, circuit CPR39 (VT/WH), harness side and roof opening panel module C921-5, circuit CPR39 (VT/WH) harness side; and between roof opening panel switch C912-6, circuit CPR39 (VT/WH), harness side and ground.





Is the resistance less than 5 ohms between the roof opening panel switch and the roof opening panel module; and greater than 10,000 ohms between the roof opening panel switch and ground?

Yes
CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR39 (VT/WH) between the roof opening panel switch socket and overhead console C921-5. 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 F7.

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

F7 CHECK COMMON FOR AN OPEN OR SHORT TO GROUND

- Measure the resistance between roof opening panel switch C912-12, circuit CPR40 (YE/OG), harness side and roof opening panel module C921-12, circuit CPR40 (YE/OG), harness side; and between roof opening panel switch C912-12, circuit CPR40 (YE/OG), harness side and ground.





Is the resistance less than 5 ohms between the roof opening panel switch and the roof opening panel module; and greater than 10,000 ohms between the roof opening panel switch and ground?

Yes
CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR40 (YE/OG) between the roof opening panel switch socket and overhead console C921-12. 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 F8.

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

F8 CHECK CIRCUIT CPR31 (VT/BN) FOR AN OPEN OR SHORT TO GROUND

- Measure the resistance between roof opening panel switch C912-8, circuit CPR31 (VT/BN), harness side and roof opening panel module C921-6, circuit CPR31 (VT/BN), harness side; and between roof opening panel switch C912-8, circuit CPR31 (VT/BN), harness side and ground.





Is the resistance less than 5 ohms between the roof opening panel switch and the roof opening panel module; and greater than 10,000 ohms between the roof opening panel switch and ground?

Yes
CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR31 (VT/BN) between the roof opening panel switch socket and overhead console C921-6. 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 F9.

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

F9 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 . 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.
