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 SBB64 (VT/RD). Ground is provided to the roof opening panel motor/module and roof opening panel control switch through circuit GD138 (BK/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 CPR39 (VT/WH), which causes the roof opening panel to open. When the roof opening panel tilt 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 to the VENT position.

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

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

-------------------------------------------------
E1 CHECK THE POWER WINDOW OPERATION

-------------------------------------------------
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.
Refer to Wiring Diagrams for component testing. Diagrams By Number

- 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 THE ROOF OPENING PANEL SWITCH GROUND - CIRCUIT GD138 (BK/WH)

- Measure the resistance between roof opening panel switch C930-12, circuit GD138 (BK/WH), harness side and ground.

- Is the resistance less than 5 ohms?

Yes
GO to E5.

No
REPAIR the circuit. TEST the system for normal operation.

-------------------------------------------------
E5 CHECK VOLTAGE TO THE ROOF OPENING PANEL MOTOR/MODULE - CIRCUITS CBP41 (BU) AND SBB64 (VT/RD)

- Disconnect: Roof Opening Panel Motor/Module In-Line C922.
- Ignition ON.
- Measure the voltage between roof opening panel motor/module in-line C922-2, circuit CBP41 (BU), harness side and ground; and between roof opening panel motor/module in-line C922-1, circuit SBB64 (VT/RD), harness side and ground.

- Is the voltage greater than 10 volts for both measurements?

Yes
CHECK the roof opening panel motor/module jumper harness for loose pins or an open in circuits CBP41 (BU) and SBB64 (VT/RD) between roof opening panel motor/module in-line C922, component side, and roof opening panel motor/module C921, harness side. If the roof opening panel motor/module jumper harness is not OK, INSTALL a new roof opening panel motor/module jumper harness and TEST the system for normal operation. If the roof opening panel motor/module jumper harness is OK, GO to E6.

No
VERIFY Battery Junction Box (BJB) fuse 64 (30A) and Smart Junction Box (SJB) fuse (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. Diagrams By Number

-------------------------------------------------
E6 CHECK THE ROOF OPENING PANEL GROUND - CIRCUIT GD138 (BK/WH)

- Ignition OFF.
- Measure the resistance between roof opening panel motor/module in-line C922-4, circuit GD138 (BK/WH), harness side and ground.

- Is the resistance less than 5 ohms?

Yes
CHECK the roof opening panel motor/module jumper harness for loose pins or an open in circuit GD138 (BK/WH) between roof opening panel motor/module in-line C922, component side, and roof opening panel motor/module C921, harness side. If the roof opening panel motor/module jumper harness is not OK, INSTALL a new roof opening panel motor/module jumper harness and TEST the system for normal operation. If the roof opening panel motor/module jumper harness is OK, GO to E7.

No
REPAIR the circuit. TEST the system for normal operation.

-------------------------------------------------
E7 CHECK CIRCUIT CPR39 (VT/WH) FOR AN OPEN
