Roof Opening Panel

Pinpoint Test F: The Roof Opening Panel Does Not Open or Close in the VENT Position

The roof opening panel motors must be initialized whenever any of the following occur:

- the roof opening sliding glass panel motor has been removed.

- a new roof opening sliding glass panel motor has been installed.

- a new roof opening panel module assembly has been installed.

Refer to Roof Opening Panel Motor Initialization .

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

Normal Operation

The roof opening panel uses an integrated motor and module to operate the roof opening panel sliding glass.

The roof opening sliding glass panel motor receives voltage from the accessory delay relay when the ignition is in the ACC or RUN position and voltage at all times through another circuit. Ground is supplied to the roof opening sliding glass panel motor and roof opening panel switch. When the roof opening panel TILT switch is pressed, the roof opening panel switch supplies a ground signal to the sliding glass panel motor, which causes the roof opening sliding glass panel to move to the VENT position. When the roof opening panel TILT switch is pulled, the roof opening panel switch supplies a ground signal to the sliding glass panel motor, which causes the roof opening sliding glass panel to move towards the CLOSED position or until the switch is released.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Roof opening panel switch

- Roof opening sliding glass panel motor

- Roof opening sliding glass panel motor not initialized

PINPOINT TEST F : THE ROOF OPENING PANEL DOES NOT OPEN OR CLOSE IN THE VENT POSITION

NOTE: 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.

F1 CHECK THE ROOF OPENING PANEL MOTOR FOR INITIALIZATION

- Carry out the roof opening panel motor initialization procedure. Refer to Roof Opening Panel Motor Initialization .

Is the concern still present?

Yes
GO to F2.

No
The system is operating normally at this time. The roof opening panel motor was not initialized.

F2 CHECK THE ROOF OPENING PANEL SWITCH

- Ignition OFF.

- Disconnect: Roof Opening Panel Switch C9001.

- Carry out the roof opening panel switch component test.

Did the roof opening panel switch pass the component test?

Yes
GO to F3.

No
INSTALL a new roof opening panel switch. REFER to Roof Opening Panel Control Switch . TEST the system for normal operation.

F3 CHECK THE ROOF OPENING PANEL CONTROL CIRCUIT FOR AN OPEN

- Disconnect: Roof Opening Panel Motor Assembly C920.

- Measure the resistance between roof opening panel switch C9001-6, circuit CPR38 (WH/BU), harness side and roof opening panel motor assembly C920-6, circuit CPR38 (WH/BU) harness side.






Is the resistance less than 5 ohms?

Yes
GO to F4.

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

F4 CHECK THE ROOF OPENING PANEL MOTOR WIRING HARNESS

- Check the roof opening panel motor wiring harness for loose pins, an open or a short between roof opening panel motor assembly C920-6, circuit CPR38, component side and the roof opening panel sliding glass motor harness connector.

Is the roof opening panel motor wiring harness OK?

Yes
GO to F5.

No
INSTALL a new roof opening panel motor wiring harness. REFER to Roof Opening Panel Motor Wiring Harness . INITIALIZE the roof opening panel motor. REFER to Roof Opening Panel Motor Initialization . TEST the system for normal operation.

F5 CHECK THE ROOF OPENING SLIDING GLASS PANEL MOTOR FOR CORRECT OPERATION

- Disconnect all roof opening panel motor connectors.

- Check for:
- corrosion.

- bent or pushed-out pins.


- Connect all roof opening panel motor 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 sliding glass panel motor. REFER to Roof Opening Panel Motor - Sliding Front Panel . INITIALIZE the roof opening panel motor. REFER to Roof Opening Panel Motor Initialization . 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.
