    • Is the resistance less than 5 ohms? 
    • Yes  : GO to F5.
    • 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.
    • 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.
