    1. YES  : Go to  E6.
    2. VERIFY Smart Junction Box (SJB) fuse 12 (7.5A) and Battery Junction Box (BJB) fuse 33 (20A) are OK. If OK, REPAIR the circuit. TEST the system for normal operation. If not OK, REFER to the appropriate Wiring Diagrams to identify the possible causes of the circuit short. TEST the system for normal operation.
  6. E6 CHECK THE ROOF OPENING PANEL GROUND - CIRCUIT GD139 (BK/YE) 
    • Key in OFF position.

    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  E7.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  7. E7 CHECK CIRCUIT CPR39 (VT/WH) FOR AN OPEN 
    • Measure the resistance between overhead console C912-4, circuit CPR39 (VT/WH), and roof opening panel motor/module C921-11, circuit CPR39 (VT/WH) harness side.
      • Fig 3: Checking Circuit CPR39 (VT/WH) For Open
      GF0028527Courtesy of FORD MOTOR CO.
    • Is the resistance less than 5 ohms? 
    1. YES  : CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR39 (VT/WH) between the roof opening panel switch socket and overhead console C912-4. 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  E8.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  8. E8 CHECK CIRCUIT CPR40 (YE/OG) FOR AN OPEN 
    • Measure the resistance between overhead console C912-7, circuit CPR40 (YE/OG), and roof opening panel motor/module C921-6, circuit CPR40 (YE/OG) harness side.
      • Fig 4: Checking Circuit CPR40 (YE/OG) For Open
      GF0028528Courtesy of FORD MOTOR CO.
    • Is the resistance less than 5 ohms? 
    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 C912-7. 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  E9.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  9. E9 CHECK CIRCUIT CPR31 (VT/BN) FOR AN OPEN 
    • Measure the resistance between overhead console C912-3, circuit CPR31 (VT/BN), and roof opening panel motor/module C921-5, circuit CPR31 (VT/BN) harness side.
