Pinpoint Test F: The Roof Opening Panel Does Not Open Or Close In Vent Position

• 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  .

• Ignition OFF.
• Disconnect: Roof Opening Panel Switch C912.
• Carry out the Roof Opening Panel Switch Component Test.

  Refer to OEM WIRING DIAGRAMS COMPONENT TESTING 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.

• 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.

• 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.

• 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.
