FULL OPEN RETRACTABLE ROOF

Automatic Roof Operation (Auto Mode)

Automatic Operation is movement of the roof to either the full open or full closed position without the vehicle operator continually pressing one of the three roof switch buttons. Anti-pinch detection is active in auto mode.

Pressing one of the three roof switch buttons for less than 500 milliseconds will result in the roof moving automatically. The roof will continue movement until either the full open or full closed position is reached or the vehicle operator interrupts movement by pressing any roof switch button.

Manual Roof Operation (Manual Mode)

Manual Operation is movement of the roof while the vehicle operator is continually pressing one of the three roof switch buttons. Roof movement is stopped as soon as the button is released. Anti-pinch detection is not active in manual mode.

Pressing one of the three roof switch buttons for more than 500 milliseconds will result in the roof moving manually. While in manual mode, the roof will move in the desired direction until either the full open or full closed position is reached or the roof switch button is released.

Front Open

To open the Front of the roof from the closed position press the vehicle most rearward roof switch button. Once the roof is in the front open mode , only the front of the roof can be controlled by the vehicle operator. Use the vehicle most rearward roof switch button to further open the roof, or the vehicle most forward roof switch button to close the roof. Once the roof is fully closed the roof will exit the front open mode .

Rear Open

To open the Rear of the roof from the closed position press the vehicle most forward roof switch button. Once the roof is in the rear open mode , only the rear of the roof can be controlled by the vehicle operator. Use the vehicle most forward roof switch button to further open the roof, or the vehicle most rearward roof switch button to close the roof. Once the roof is fully closed the roof will exit the rear open mode .

Global Close

Pressing the roof switch center button with the roof in any position other than closed position, will result in the roof closing. A short press for less than 500 milliseconds will result in automatic mode closing, and a long press for more than 500 milliseconds will result in manual mode closing.

Power Modes Of Operation

The Electronic Control Unit (ECU) (sometimes referred to as the Power Top Control Module) will function as follows in respect to Country Code Configuration:

Key out door open - (No Function all Markets) Remote Start active - (No Function all Markets) Accessory Delay, Front Doors closed, key out - (Manual & Automatic Function for North American Markets) (Manual Function Only for Non-North American Markets) Key in Accessory Mode - (Manual & Automatic Function for North American Markets) (Manual Function Only for Non-North American Markets) Ignition On (Engine Off) - (Manual & Automatic Function all Markets) Ignition On (Engine Running) - (Manual & Automatic Function all Markets)

FULL OPEN RETRACTABLE ROOF

Any diagnosis of the FULL OPEN RETRACTABLE ROOF (FORR) system should begin with a scan tool and proper Diagnostic Procedures. The scan tool can provide confirmation that the FORR Electronic Control Unit (ECU), (sometimes referred to as the Power Top Control Module) is functional, that all of the electronic modules are sending and receiving the proper messages on the Controller Area Network (CAN) Data Bus, and that the power to the FORR is being sent the proper hard wired output by the FORR switch.

Check the condition of the circuit protection and inspect all wiring connector pins for proper engagement and continuity. For complete circuit diagrams, refer to SYSTEM WIRING DIAGRAMS . The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views wire harness connectors, splices and grounds.

NOTE: Roof limits:

Motor Thermal Protection: The ECU Calculates the internal motor temperature. When the calculated temperature exceeds 365F (185C), the ECU allows the roof to only close. At 392F (200C) The ECU prevents motor movement. System Low Temperature Operation: (Via the Vehicle Ambient Temp Sensor) At 14F (-10C ) the ECU does not allow the system to vent without stopping the other motor. At -4F (-20C ) the motors are allowed to close only. Speed Thresholds: At 86 m.p.h. (138 km/h) we stop operation and at 81 m.p.h. (129 km/h) we resume operation.

NOTE: For the FORR initialization procedure, see STANDARD PROCEDURE.

POWER FULL OPEN RETRACTABLE ROOF MODULE

POWER FULL OPEN RETRACTABLE ROOF MODULE

The Electronic Control Unit (ECU) (sometimes referred to as the Power Top Control Module) is located at the rear of the vehicle roof next to the Full Open Retractable Roof (FORR) motors. The ECU is mounted to the FORR frame assembly with two screws. Three wire harness connectors are used to supply inputs to the ECU and send outputs to the FORR motors.

The ECU communicates via the Controller Area Network (CAN) data bus circuit and can be diagnosed and receive software updates with the use of a diagnostic scan tool.

POWER FULL OPEN RETRACTABLE ROOF MODULE

This vehicle is available with the Full Open Retractable Roof (FORR) option. Marketed as Sky Slider™, the unit is made of reinforced acrylic cloth, similar to a convertible top. The FORR system receives battery feed through the "sunroof" relay and a 25 amp mini fuse located in the Totally Integrated Power Module (TIPM). The FORR system power is supplied when the ignition switch is in the RUN and ACCESSORY positions. The sunroof will operate normally with the key in any position while the Accessory Delay system is active.

The FORR utilizes a single Electronic Control Unit (ECU) (sometimes referred to as the Power Top Control Module) to control the movement of the power top. The ECU sends a reference voltage to and receives inputs back from the power top switch via a hardwired connection. The ECU responds to the switch input by controlling one or both of the power top motors via a hardwired connection.

The ECU communicates via the Controller Area Network (CAN) data bus circuit and can be diagnosed and receive software updates with the use of a diagnostic scan tool. The ECU continually monitors ambient temperature and vehicle speed inputs from the instrument cluster, sometimes referred to as the Cab Compartment Node (CCN). The ECU also receives vehicle configuration data from the Totally Integrated Power Module (TIPM) to ensure proper operation related to geographical location (i.e. North American markets

versus Export markets).
