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 when repairs are carried out on any part of the roof opening panel system, including: whenever the roof opening panel motor has been removed from the roof opening panel system, the roof opening panel glass 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, a new roof opening panel glass 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 CBP41 (BU) when the key is in the ACC or RUN position and voltage at all times through circuit SBP19 (BU/RD). The roof opening panel motor/module provides ground to the roof opening panel switch through circuit CPR39 (VT/WH). When the roof opening panel SLIDE switch is pulled, 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 SLIDE switch is pressed, 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.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Roof opening panel switch
- Roof opening panel motor/module assembly
- Accessory delay relay
PINPOINT TEST E: THE ROOF OPENING PANEL DOES NOT OPEN OR CLOSE
-------------------------------------------------
E1 CHECK THE POWER WINDOWS
- Ignition ON.
- Verify the power windows operate.
- Do the power windows operate?
Yes
GO to E2.
No
REFER to Windows to diagnose the accessory delay relay circuit.
-------------------------------------------------
E2 CHECK THE MOTOR/MODULE FOR INITIALIZATION
- Attempt to carry out the roof opening panel motor initialization procedure. Refer to Roof Opening Panel Motor Initialization Programming and Relearning.
- Is the concern still present and/or does the roof opening panel motor fail to initialize?
Yes
GO to E3.
No
The system is operating normally at this time. The roof opening panel motor was not initialized.
-------------------------------------------------
E3 CHECK THE ROOF OPENING PANEL SWITCH
- Ignition OFF.
- Disconnect: Roof Opening Panel Switch C930.
- Carry out the Roof Opening Panel Switch Component Test.
- 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.
-------------------------------------------------
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 the Wiring Diagrams to identify the possible causes of the circuit short. TEST the system for normal operation.
-------------------------------------------------
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.
-------------------------------------------------
E6 CHECK CIRCUIT CPR39 (VT/WH) FOR AN OPEN
- Measure the resistance between overhead console C930-12, 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 C930-12. 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.
-------------------------------------------------
E7 CHECK CIRCUIT CPR40 (YE/OG) FOR AN OPEN
- Measure the resistance between overhead console C930-8, 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 C930-8. 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.
-------------------------------------------------
E8 CHECK CIRCUIT CPR31 (VT/BN) FOR AN OPEN
- Measure the resistance between overhead console C930-6, 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 C930-6. 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.
-------------------------------------------------
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 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.
