PRINCIPLES OF OPERATION

Roof Opening Panel
Actuating the roof opening panel switch in the forward or rearward direction supplies a ground signal to the roof opening panel module. The roof opening panel module then supplies power and ground to the roof opening panel motor. The vent and soft stop functions are controlled by the roof opening panel module and an internal roof opening panel position switch within the roof opening panel motor. These positions are obtained when an internal motor cam opens the roof opening panel position switch that removes ground to the roof opening panel module.
