Pinpoint Test H: The Roof Opening Panel Does Not Open or Close - Power Shade

Roof Opening Panel

Pinpoint Test H: The Roof Opening Panel Does Not Open or Close - Power Shade

Normal Operation

When the shade control switch is pressed, a ground signal is sent to the power shade motor through circuit CPR86 (GY/BN), which causes the power shade to open. When the shade control switch is pulled, a ground signal is sent to the power shade motor through circuit CPR85 (GN/WH), which causes the power shade to close.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Roof opening panel switch

- Power shade motor

PINPOINT TEST H : THE ROOF OPENING PANEL DOES NOT OPEN OR CLOSE - POWER SHADE

H1 CHECK THE POWER SHADE MOTOR FOR INITIALIZATION

- Carry out the power shade motor initialization procedure. Refer to Roof Opening Panel Motor Initialization .

Is the concern still present?

Yes
GO to H2.

No
The system is operating normally at this time. The power shade motor was not initialized.

H2 CHECK THE FRONT SLIDING GLASS PANEL OPERATION

- Attempt to open and close the front sliding glass panel using the roof opening panel slide switch.

Does the front sliding glass panel open and close using the slide control switch?

Yes
GO to H3.

No
GO to Pinpoint Test F to diagnose the inoperative front sliding glass panel. Pinpoint Test F: The Roof Opening Panel Does Not Open or Close - Front Sliding Glass Panel

H3 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 H4.

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

H4 CHECK CIRCUIT CPR86 (GY/BN) FOR AN OPEN OR SHORT TO GROUND

- Disconnect: Roof Opening Panel Motor/Module C921.

- Measure the resistance between roof opening panel switch C912-4, circuit CPR86 (GY/BN), harness side and roof opening panel module C921-8, circuit CPR86 (GY/BN), harness side; and between roof opening panel switch C912-4, circuit CPR86 (GY/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 CPR86 (GY/BN) between the roof opening panel switch socket and overhead console C921-8. 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 H5.

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

H5 CHECK CIRCUIT CPR85 (GN/WH) FOR AN OPEN OR SHORT TO GROUND

- Measure the resistance between roof opening panel switch C912-9, circuit CPR85 (GN/WH), harness side and roof opening panel module C921-9, circuit CPR85 (GN/WH), harness side; and between roof opening panel switch C912-9, circuit CPR85 (GN/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 CPR85 (GN/WH) between the roof opening panel switch socket and overhead console C921-9. 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 H6.

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

H6 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 power shade motor. REFER to Roof Opening Panel Motor - Shade . 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.
