Pinpoint Test E: The Roof Opening Panel Does Not Open or Close




Roof Opening Panel

Pinpoint Test E: The Roof Opening Panel Does Not Open or Close

Refer to Wiring Diagram Set 101 (Fusion/Milan/MKZ, Fusion Hybrid, Milan Hybrid, MKZ Hybrid), 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 motor/module receives voltage from the accessory delay relay when the ignition is in the ACC or RUN position. The overhead console switch supplies ground signals to the roof opening panel motor/module to operate the roof opening panel.

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
- Roof opening panel motor not initialized


PINPOINT TEST E: THE ROOF OPENING PANEL DOES NOT OPEN OR CLOSE

-------------------------------------------------
E1 CHECK THE ROOF OPENING PANEL OPERATION

- Ignition ON.
- Attempt to operate the roof opening panel to the VENT position.
- Does the roof opening panel operate to the VENT position?

Yes
GO to E2.

No
GO to E3.

-------------------------------------------------
E2 CHECK THE MOTOR/MODULE FOR INITIALIZATION

- 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 POWER WINDOWS

- Ignition ON.
- Verify the power windows operate.
- Do the power windows operate?

Yes
GO to E4.

No
REFER to Glass, Frames and Mechanisms Testing and Inspection to diagnose the accessory delay relay circuit.

-------------------------------------------------
E4 CHECK THE ROOF OPENING PANEL SWITCH

- Ignition OFF.
- Disconnect: Roof Opening Panel Switch C912.
- Carry out the Roof Opening Panel Switch component test.

- 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 Service and Repair. 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 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

- 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 SWITCH COMMON CIRCUIT 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 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.




- Is the resistance less than 5 ohms?

Yes
CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR38 (WH/BU) between the roof opening panel switch socket and overhead console C912-2. 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 E11.

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

-------------------------------------------------
E11 CHECK THE ROOF OPENING PANEL MOTOR/MODULE FOR CORRECT OPERATION

- Disconnect the roof opening panel motor/module connector.
- Check for:
- corrosion.
- bent or pushed-out pins.
- Connect the roof opening panel motor/module connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
