23 - 462 CONVERTIBLE TOP
When the PTCM senses that the rear bow is up all the way by the rear bow travel sensor (base side), the PTCM
energizes the Right Rotation Relay and the Hydraulic Solenoids S1, S2, and S3. The Power Top Hydraulic Assem-
bly delivers hydraulic fluid to the following areas:
• Hydraulic fluid is delivered through Hydraulic Solenoid S3 to the base side of the rear bow latch cylinder to
keep the latch unlocked.
• Hydraulic fluid is delivered through Hydraulic Solenoids S2 and S3 to both sides of the proportioning valve.
When equal pressure is applied to both sides of the proportioning valve, hydraulic fluid is allowed to travel to
the rod side of both rear bow cylinders to stabilize the rear bow while the tonneau cover opens.
• Hydraulic fluid is delivered through Hydraulic Solenoids S2 and S3 to the rod and base side of both main
cylinders to stabilize the top while the tonneau cover opens.
• Hydraulic fluid is delivered through Hydraulic Solenoids S2 and then S1 to the base side of the tonneau cover
latch cylinder to unlock the tonneau cover.
• Hydraulic fluid is delivered through Hydraulic Solenoids S2 and then S1 to the rod and base side of the ton-
neau cover cylinder to raise the tonneau cover. Even though there is hydraulic pressure on both sides of the
tonneau cover cylinder, the cylinder slowly moves to open the tonneau cover because there is a greater sur-
face area on the base side of the cylinder than the rod side.
