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 .
- Was the roof opening panel initialization procedure successful?
- Yes : The system is operating normally at this time. The roof opening panel motor was not initialized.
- No : GO to F2.
- F2 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 ROOF OPENING PANEL CONTROL SWITCH for component testing.
- 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 overhead console 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 : CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR38 (WH/BU) between the roof opening panel switch socket and overhead console C912-3. 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 F4.
- No : REPAIR the circuit. TEST the system for normal operation.
- F4 CHECK CIRCUIT CPR40 (YE/OG) FOR AN OPEN
- Measure the resistance between overhead console C912-8, 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 : 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 C912-8. 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 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 . 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.
