Operation







OPERATION

Hydraulic Cylinder - Rod Extended





The hydraulic pump assembly supplies pressurized oil through the hydraulic line (1) and into the hydraulic cylinder on the base side of the cylinder. The pressurized oil enters the hydraulic cylinder where it fills the cavity (6) and forces the piston (5) to move the rod (3) to a fully extended position.

Hydraulic Cylinder - Rod Retracted





The hydraulic pump assembly supplies pressurized oil through the hydraulic line (2) and into the hydraulic cylinder on the rod side of the cylinder. The pressurized oil enters the hydraulic cylinder where it fills the cavity (5) and forces the piston (6) to move the rod (3) to a fully retracted position.

Hydraulic Cylinder - Travel Sensors





The hydraulic cylinders are equipped with hall-effect style switches, referred to as Travel Sensors. The travel sensors (2) and (3) are used to detect the position of the rod (5) inside the hydraulic cylinder (7). The position of the rod is a critical input to the Power Top Control Module (PTCM). Based on this input, the PTCM can determine the positioning sequence of the convertible top. There are two sensors located on the left main hydraulic cylinder, and the left rear bow hydraulic cylinder. Only the tonneau cover hydraulic cylinder has one sensor. The sensors are defined as either the base side (10) or the rod side (6). The travel sensors for the main cylinder and the rear bow cylinder are serviced together. The sensors are not serviced separately. The tonneau cover travel sensor is serviced with the hydraulic pump assembly.
