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
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, the roof opening panel glass has been removed from the roof opening panel system, the roof opening panel assembly has been removed from the vehicle, a new roof opening panel motor has been installed, a new roof opening panel glass has been installed or 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 a 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 receives voltage from the accessory delay relay through circuit CBP05 (YE) when the key is in the ACC or RUN position and voltage at all times through circuit SBP01 (RD). Ground is supplied to the roof opening panel motor/module and the roof opening panel control switch through circuit GD133 (BK). When the roof opening panel TILT switch is pressed, a ground signal is sent to the roof opening panel motor/module through circuit CPR38 (WH/BU), which causes the roof opening panel to open to the VENT position. When the roof opening panel SLIDE or TILT switch is pulled, a ground signal is sent to the roof opening panel motor/module through circuit CPR40 (YE/OG), which causes the roof opening panel to close.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Roof opening panel switch
- Roof opening panel motor/module assembly
PINPOINT TEST F: THE ROOF OPENING PANEL DOES NOT OPEN OR CLOSE IN VENT POSITION
-------------------------------------------------
F1 CHECK THE MOTOR/MODULE FOR INITIALIZATION
- Attempt to carry out the roof opening panel motor initialization procedure. Refer to Roof Opening Panel Motor Initialization Programming and Relearning.
- Is the concern still present, or does the roof opening panel motor fail to initialize?
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 C912.
- Carry out the roof opening panel switch component test.
- Is the roof opening panel switch OK?
Yes
GO to F3.
No
INSTALL a new roof opening panel switch. TEST the system for normal operation.
-------------------------------------------------
F3 CHECK CIRCUIT CPR38 (WH/BU) FOR AN OPEN
- Measure the resistance between roof opening panel switch C912-3, circuit CPR38 (WH/BU), harness side and roof opening panel motor/module C921-4, 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 CIRCUIT CPR40 (YE/OG) FOR AN OPEN
- Measure the resistance between roof opening panel switch C912-8, circuit CPR40 (YE/OG), harness side and roof opening panel motor/module C921-10, circuit CPR40 (YE/OG), harness side.
- Is the resistance less than 5 ohms?
Yes
GO to F5.
No
REPAIR the circuit. TEST the system for normal operation.
-------------------------------------------------
F5 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 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.
