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 SBP47 (WH/RD) when the key is in the ACC or RUN position and voltage at all times through circuit SBP19 (BU/RD). Ground is supplied to the roof opening panel motor/module through circuit GD133 (BK). The roof opening panel motor/module provides ground to the roof opening panel control 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
- Wiring, terminals or connectors
- Roof opening panel control switch
- Roof opening panel motor/module assembly
PINPOINT TEST E: THE ROOF OPENING PANEL DOES NOT OPEN OR CLOSE
-------------------------------------------------
E1 CHECK THE POWER WINDOW OPERATION
- Ignition ON.
- Verify the power windows operate.
- Do the power windows operate?
Yes
GO to E2.
No
REFER to Windows and Glass to diagnose the accessory delay relay circuit.
-------------------------------------------------
E2 REINITIALIZE THE ROOF OPENING PANEL MOTOR/MODULE
- Carry out the roof opening panel motor initialization procedure. Refer to Roof Opening Panel Motor Initialization Programming and Relearning.
- Is the concern still present?
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 CONTROL SWITCH
- Ignition OFF.
- Disconnect: Roof Opening Panel Control Switch C912.
- Carry out the roof opening panel control switch component test.
- Is the roof opening panel control switch OK?
Yes
GO to E4.
No
INSTALL a new roof opening panel control switch. TEST the system for normal operation.
-------------------------------------------------
E4 CHECK VOLTAGE TO THE ROOF OPENING PANEL MOTOR/MODULE - CIRCUITS SBP47 (WH/RD) AND SBP19 (BU/RD)
- Ignition OFF.
- Disconnect: Roof Opening Panel Motor/Module C9015.
- Ignition ON.
- Measure the voltage between roof opening panel motor/module C9015-3, circuit SBP47 (WH/RD) and C9015-6, circuit SBP19 (BU/RD), harness side and ground.
- Are the voltages greater than 10 volts?
Yes
GO to E5.
No
VERIFY Smart Junction Box (SJB) fuse 19 (25A) is OK. If OK, REPAIR the circuit in question. 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. Diagrams By Number
-------------------------------------------------
E5 CHECK THE ROOF OPENING PANEL GROUND - CIRCUIT GD133 (BK)
- Ignition OFF.
- Measure the resistance between roof opening panel motor/module C9015-1, 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 roof opening panel control switch C912-12, circuit CPR39 (VT/WH), and roof opening panel motor/module C9015-2, circuit CPR39 (VT/WH) harness side.
- Is the resistance less than 5 ohms?
Yes
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 roof opening panel control switch C912-8, circuit CPR40 (YE/OG), and roof opening panel motor/module C9015-10, circuit CPR40 (YE/OG), harness side.
- Is the resistance less than 5 ohms?
Yes
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 roof opening panel control switch C912-6, circuit CPR31 (VT/BN), and roof opening panel motor/module C9015-5, circuit CPR31 (VT/BN), harness side.
- Is the resistance less than 5 ohms?
Yes
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.
