    1. 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 C930-3. 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  F5 .
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  5. F5 CHECK THE ROOF OPENING PANEL MOTOR/MODULE FOR CORRECT OPERATION 
    • Disconnect all roof opening panel motor/module connectors.
