Pinpoint Test E: The Roof Opening Panel Does Not Open Or Close

  1. E1 CHECK THE MOTOR/MODULE FOR INITIALIZATION 
    • Yes  : GO to E2.
    • No  : The system is operating normally at this time. The roof opening panel motor was not initialized.
  2. E2 CHECK THE POWER WINDOWS 
    • Ignition ON.
    • Verify the power windows operate.
    • Do the power windows operate? 
  3. E3 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 E4.
    • No  : INSTALL a new roof opening panel switch. TEST the system for normal operation.
  4. E4 CHECK VOLTAGE TO THE ROOF OPENING PANEL MOTOR/MODULE - CIRCUITS CBP41 (BU) AND SBP19 (BU/RD) 
    • Ignition OFF.
    • Disconnect: Roof Opening Panel Motor/Module C921.
    • Ignition ON.
    • Measure the voltage between roof opening panel motor/module C921-3, circuit CBP41 (BU) and C921-6, circuit SBP19 (BU/RD), harness side and ground.

    • Are the voltages greater than 10 volts, but less than 16 volts? 
    • Yes  : GO to E5.
    • No  : VERIFY Smart Junction Box (SJB) fuses 19 (25A) and 41 (15A) are OK. If OK, REPAIR the circuit. If not OK, REFER to POWER TOP/SUNROOF to identify the possible causes of the circuit short. TEST the system for normal operation.
  5. E5 CHECK THE ROOF OPENING PANEL GROUND - CIRCUIT GD133 (BK) 
    • Ignition OFF.
    • Measure the resistance between roof opening panel motor/module C921-1, circuit GD133 (BK), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to E6.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  6. E6 CHECK CIRCUIT CPR39 (VT/WH) FOR AN OPEN 
    • Measure the resistance between overhead console C921- 12, circuit CPR39 (VT/WH), and roof opening panel motor/module C921-2, circuit CPR39 (VT/WH) 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 CPR39 (VT/WH) between the roof opening panel switch socket and overhead console C921-12. 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 E7.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  7. E7 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 E8.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  8. E8 CHECK CIRCUIT CPR31 (VT/BN) FOR AN OPEN 
    • Measure the resistance between overhead console C912-6, circuit CPR31 (VT/BN), and roof opening panel motor/module C921-5, circuit CPR31 (VT/BN) 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 CPR31 (VT/BN) between the roof opening panel switch socket and overhead console C912-6. 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.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  9. E9 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.
