Pinpoint Test E: The Roof Opening Panel Does Not Open or Close
Refer to Wiring Diagram Set 101, Roof Opening Panel for schematic and connector information. Diagrams By Number
The roof opening panel motor must be initialized whenever the roof opening panel motor has been removed from the roof opening panel system, the roof opening panel assembly has been removed from the vehicle, a new roof opening panel motor has been installed or a new roof opening panel assembly has been installed. Refer to Roof Opening Panel Motor Initialization Programming and Relearning.
Normal Operation
The roof opening panel uses an integrated motor and module to operate the roof opening panel. A new roof opening panel motor/module is installed as an assembly.
The roof opening panel motor/module receives voltage from the accessory delay relay through circuit CBP02 (GN) when the key is in the ACC or RUN position and voltage at all times through circuit SBB33 (RD). Ground is supplied to the motor/module through circuit GD139 (BK/YE). The roof opening panel motor/module provides ground to the roof opening panel switch through circuit CPR39 (VT/WH). When the roof opening panel switch is pressed to the CLOSED position, a ground signal is sent to the roof opening panel motor/module through circuit CPR40 (YE/OG), which causes the roof opening panel to close. When the roof opening panel switch is pressed to the OPEN position, a ground signal is sent to the roof opening panel motor/module through circuit CPR31 (VT/BN), which causes the roof opening panel to open.
One-touch open and one-touch close features are enabled when the motor/module receives a ground input from the roof opening panel switch through circuit CPR38 (WH/BU).
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Inoperative roof opening panel switch
- Inoperative roof opening panel motor/module assembly
- Inoperative accessory delay relay
- Roof opening panel motor not initialized

Yes
GO to E5.
No
INSTALL a new roof opening panel switch. REFER to Roof Opening Panel Control Switch Service and Repair. TEST the system for normal operation.
-------------------------------------------------
E5 CHECK VOLTAGE TO THE ROOF OPENING PANEL MOTOR/MODULE - CIRCUITS CBP02 (GN) AND SBB33 (RD)
- Ignition OFF.
- Disconnect: Roof Opening Panel Motor/Module C921.
- Ignition ON.
- Measure the voltage between roof opening panel motor/module C921-2, circuit CBP02 (GN) and C921-1, circuit SBB33 (RD), harness side and ground.
- Are the voltages greater than 10 volts, but less than 16 volts?
Yes
GO to E6.
No
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 Wiring Diagrams to identify the possible causes of the circuit short. TEST the system for normal operation.
-------------------------------------------------
E6 CHECK THE ROOF OPENING PANEL GROUND - CIRCUIT GD139 (BK/YE)
- 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
GO to E7.
No
REPAIR the circuit. TEST the system for normal operation.
-------------------------------------------------
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.
- 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 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.
- 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 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.
