When the PTCM senses that the tonneau cover has been lowered and locked down by the tonneau cover travel
sensor (base side) and the tonneau cover switch, the PTCM energizes the Right Rotation Relay and the Hydraulic
Solenoid S4. The Power Top Hydraulic Assembly delivers hydraulic fluid to the following areas:
• Hydraulic fluid is delivered through Hydraulic Solenoid S4 to the base side of both rear bow cylinders to lower
the rear bow onto the tonneau cover.
• Hydraulic fluid is delivered through Hydraulic Solenoid S4 to the rod side of the rear bow latch cylinder to lock
down the rear bow.
