Pinpoint Test F: The Express Open/Close is Inoperative

Refer to Wiring Diagram Set 101 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Roof Opening Panel for schematic and connector information. Diagrams By Number

Normal Operation

When the rear portion of the roof opening panel switch is pressed to the second detent position, a ground signal is sent to the roof opening panel motor through circuit CPR40 (YE/OG) and CPR38 (WH/BU) which causes the roof opening panel to perform a one-touch open operation. When the front portion of the roof opening panel switch is pressed to the second detent position, a ground signal is sent to the roof opening panel motor through circuit CPR31 (VT/BN) and CPR38 (WH/BU) which causes the roof opening panel to perform a one-touch close operation (or tilt if roof opening panel glass is already in the fully CLOSED position).

This pinpoint test is intended to diagnose the following:
- Roof opening panel motor initialization
- Wiring, terminals or connectors
- Roof opening panel motor
- Roof opening panel module



PINPOINT TEST F: THE EXPRESS OPEN/CLOSE IS INOPERATIVE

-------------------------------------------------
F1 CHECK THE ROOF OPENING PANEL MOTOR 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 F2.

No
The system is operating normally at this time. The roof opening panel motor was not initialized.

-------------------------------------------------
F2 CHECK THE ROOF OPENING PANEL SWITCH


- Ignition OFF.
- Disconnect: Roof Opening Panel Switch C912.
- Carry out the roof opening panel control switch component test.

- Did the roof opening panel control switch pass the component test?

Yes
GO to F3.

No
INSTALL a new roof opening panel switch. TEST the system for normal operation.

-------------------------------------------------
F3 CHECK CIRCUIT CPR38 (WH/BU) FOR AN OPEN OR SHORT TO GROUND


- Disconnect: Roof Opening Panel Module C921.
- Measure the resistance between the roof opening panel motor C921-7, circuit CPR38 (WH/BU), harness side and roof opening panel switch C912-2, circuit CPR38 (WH/BU), harness side; and between roof opening panel motor C921-7, circuit CPR38 (WH/BU), harness side and ground.




- Is the resistance less than 5 ohms between the roof opening panel motor and roof opening panel switch; and greater than 10,000 ohms between the roof opening panel motor and ground?

Yes
GO to F4.

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

-------------------------------------------------
F4 CHECK THE ROOF OPENING PANEL MOTOR FOR CORRECT OPERATION


- Check all roof opening panel motor and switch electrical connectors.
- Check for:
- corrosion.
- bent pins.
- pushed-out pins.
- Connect all roof opening panel motor and switch electrical 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. 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.
