E4 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 COMPONENT TESTING for component testing.
- Is the roof opening panel switch OK?
  - Yes: GO to E5.
  - No: INSTALL a new roof opening panel switch. REFER to Roof Opening Panel Control Switch . TEST the system for normal operation.
E5 CHECK VOLTAGE TO THE ROOF OPENING PANEL MOTOR/MODULE
- Ignition OFF.
- Disconnect: Roof Opening Panel Motor/Module C921.
- Ignition ON.
- Measure the voltage between roof opening panel motor/module C921-2, circuit CBP41 (BU) and C921-1, circuit SBB33 (RD), harness side and ground.

- Is the voltage greater than 10 volts?
  - Yes: GO to E6.
  - No: VERIFY Smart Junction Box (SJB) fuse 41 (15A) 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 Wiring Diagrams information to identify the possible causes of the circuit short. TEST the system for normal operation.
E6 CHECK THE ROOF OPENING PANEL GROUND
- Ignition OFF.
- Measure the resistance between roof opening panel motor/module C921-4, circuit GD139 (BK/YE), harness side and ground.

- 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 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.
  - No: REPAIR the circuit. TEST the system for normal operation.
E8 CHECK SWITCH CLOSE CIRCUIT 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.

- 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 C912-7. 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.
  - No: REPAIR the circuit. TEST the system for normal operation.
E9 CHECK SWITCH OPEN CIRCUIT 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.

- 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 C912-3. 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 E10.
  - No: REPAIR the circuit. TEST the system for normal operation.
E10 CHECK SWITCH AUTO CIRCUIT FOR AN OPEN
- Measure the resistance between overhead console C912-2, circuit CPR38 (WH/BU) and roof opening panel motor/module C921-7, circuit CPR38 (WH/BU), harness side.
