Convertible Top: Locations

Convertible Top

COMPONENT LOCATION







INTRODUCTION
The power-operated convertible top consists of a fabric canopy with a 'Thinsulate' inner liner, which is fitted to a steel frame with cast linkages.

The fully automatic flush mounted aluminium tonneau panel conceals the stowed top and incorporates the Roll-over Protection System doors in its trim panel. The top has a low-stack height of 200 mm (7.9 in) and manual roller blind luggage separator to optimize the luggage compartment volume. The open and close time of the top is approximately 17 seconds depending on ambient temperature and battery voltage.

A heated glass backlight is high frequency welded to the canopy.

A pump motor and valve block provides hydraulic power to open and close the top while an electric motor controls a tension bow system to latch and unlatch the top. A single hold-down switch located in the roof console operates the top. This switch also operates the rear quarter glass.

In the event that the top cannot be powered to the raised or lowered position, provision is made for manual operation.

CAUTION: The convertible top frame is located on the vehicle body accurately using a steel adjuster plate, under no circumstances must the top steel adjuster plates be released. For more information refer to the adjuster plate section.

COMPONENTS
A control module, located behind the LH rear seat, controls the power-operated convertible top. The control module operates the top based on data received on the Controller Area Network (CAN) bus and from the hardwired components described below:







A - Tension Bow Sensors







The tension bow sensors are Hall effect sensors located in the tension bow piston tube assembly. The piston tube assembly is located next to the LH tension bow linkage. These sensors inform the control module as to the position of the convertible top tension bow assembly.


B - Main Tension Bow Sensors







The main tension bow sensors are Hall effect sensors located in the main tension bow piston tube assembly. The piston tube assembly is located on the RH main bearing bracket assembly. These sensors sense the position of the main tension bow piston so the control module knows exactly what position the convertible top is in.

C - Tonneau Panel Open Sensor







The tonneau panel open sensor is a Hall effect sensor located in the tonneau panel piston tube assembly. The piston tube assembly is located between the RH base latch plate and the lever assembly. This sensor informs the control module of when the tonneau panel is in the open position so the convertible top can be stowed.

D - Tonneau Panel Switch 1







Tonneau panel switch 1 is located on the RH lever assembly. This switch is a normally open microswitch that, when switched to ground, informs the control module that the RH side of the tonneau panel is closed.


E - Pump Motor Temperature Sensor







The hydraulic fluid temperature sensor is a Negative Temperature Coefficient (NTC) sensor, which is integral to the pump assembly. The sensor informs the control module as to the temperature of the hydraulic fluid. If the fluid temperature exceeds a predetermined value, the control module will stop pump operation to prevent the valve block from overheating. Once the fluid temperature decreases below the predetermined value, the control module will then resume pump operation.


F - Tonneau Panel Switch 2







Tonneau panel switch 2 is located on the LH latch base plate assembly. This switch is a normally open microswitch that, when switched to ground, informs the control module that the LH side of the tonneau panel is closed.

G - Luggage Separator Position Sensor







The Luggage separator position sensor is a Hall effect sensor located on the LH luggage separator housing bracket. The sensor informs the control module of when the separator is in the correct position. When the separator is in the correct position there is enough space in the luggage compartment to stow the convertible top when open.

H - Front Latch Open and Close Sensors







The front latch open and closed sensors are Hall effect sensors located in the LH front latch plate. These sensors inform the control module of when the latch is in the open or closed position.

I - Convertible Top Latched Sensor







The convertible top latched sensor is a Hall effect sensor located in the LH latching bracket. The sensors function is to inform the control module of when the convertible top is in the closed position.

J - Convertible Top Open and Close Switch







The convertible top open and close switch is located in the overhead console. The switch is a momentary switch that is normally open. When switched to ground the convertible top will start its open or close motion depending on which operation has been requested.

Adjuster Plate
The convertible top frame, actuation levers and main bow hydraulic cylinder assembly is located on the vehicle body accurately using a steel adjuster plate, which is set to the body using adjustable shims.







CAUTION: Under no circumstances must the top steel adjuster plates be released, as they are set and adjusted to the body during manufacture, providing an accurate location for the convertible top frame. Service action and special tools will be required to reset the plate if this area of the vehicle requires service.

Tonneau Panel Cover
A fully automatic flush mounted aluminium tonneau cover panel protects the stowed top.

WARNING: Special care must be taken when carrying out maintenance in the area underneath the aluminum tonneau cover. After approximately five minutes the hydraulic pressure is lost due to the release of the spool valves to prevent the valves overheating. A suitable support must be used to prevent the aluminum tonneau cover falling when the hydraulic pressure is released.

The aluminum tonneau cover panel trim also incorporates Roll Over Protection hoop doors. The roll over protection system is deployed through the hoop doors and rear screen in the event of a vehicle roll over situation.







The hydraulic pump, motor and valve block assembly is located in the RH luggage area. The fluid reservoir is filled with Pentosin hydraulic oil. Two fluid levels are marked on the pump reservoir body, the upper mark denotes the fluid level when the top is fully lowered and the lower mark denotes the level when the top is fully raised. The hydraulic pump supplies a maximum pressure of approximately 140 bar during convertible top operation. When the pump is idle the system pressure is approximately 0.1 bar

NOTE: The convertible top hydraulic system is 'self-bleeding' and does not require action to expel any trapped air.
