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

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

NOTE: The roof opening panel motor must be initialized when repairs are carried out on any part of the roof opening panel system, including:
- whenever the roof opening panel motor has been removed from the roof opening panel system.
- whenever the roof opening panel glass has been removed from the roof opening panel system.
- whenever the roof opening panel assembly has been removed from the vehicle.
- whenever a new roof opening panel motor has been installed.
- whenever a new roof opening panel glass has been installed.
- whenever a new roof opening panel assembly has been installed.

Refer to Roof Opening Panel Motor Initialization Programming and Relearning.

Normal Operation

The roof opening panel uses an integrated motor and module to operate the roof opening panel. A new roof opening panel motor/module is installed as an assembly.

The roof opening panel motor/module and switch receive voltage from the Central Junction Box (CJB) when the ignition is in the RUN position. The roof opening panel switch supplies voltage signals to the roof opening panel motor/module to operate the roof opening panel.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- Roof opening panel switch
- Roof opening panel motor/module

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

-------------------------------------------------
F1 CHECK THE ROOF OPENING PANEL SWITCH

- Ignition OFF.
- Disconnect: Roof Opening Panel Switch C912.
- Carry out the roof opening panel switch component test.
Refer to Sunroof / Moonroof Switch for component testing.

- Is the roof opening panel switch OK?

Yes
GO to F2.

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

-------------------------------------------------
F2 CHECK THE ROOF OPENING PANEL CONTROL CIRCUIT FOR AN OPEN

- Disconnect: Roof Opening Panel Motor/Module C921.
- Measure the resistance between roof opening panel switch C912-3, circuit CPR38 (WH/BU), and roof opening panel motor/module C921-4, circuit CPR38 (WH/BU) harness side.




- Is the resistance less than 5 ohms?

Yes
GO to F3.

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

-------------------------------------------------
F3 CHECK THE ROOF OPENING PANEL CONTROL CIRCUIT FOR AN OPEN

- Measure the resistance between roof opening panel switch C912-5, circuit CPR40 (YE/OG), and roof opening panel motor/module C921-10, circuit CPR40 (YE/OG), 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/MODULE FOR CORRECT OPERATION

- Inspect the roof opening panel motor/module electrical connector.
- Check for:
- corrosion.
- bent pins.
- pushed-out pins.
- Connect the roof opening panel motor/module connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?

Yes
INSTALL a new roof opening panel motor/module. REFER to Roof Opening Panel Motor 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.
