Power Top Control Module: Operation
WARNING: This page is about a different car, the 2006 Chrysler Crossfire. However, it is still accessible from the selected car via links, so may be relevant.
The PTCM controls each set of hydraulic cylinders through the power top hydraulic assembly. The power top hydraulic assembly operates the hydraulic cylinders and is monitored by the PTCM to control each step of the raising and lowering of the convertible top. The PTCM also controls both power windows through the Controller Area Network (CAN) lines to lower and raise the power windows when the power top switch is depressed.
