Principles of Operation

PRINCIPLES OF OPERATION

The roof opening panel assembly uses an integrated motor and module to operate the roof opening panel. The roof opening panel motor and module are installed new as an assembly. The roof opening panel is an electronically operated glass panel that can be opened, closed or tilted by operating the roof opening panel switch. Pressing the roof opening panel switch forward or rearward supplies a ground to the roof opening panel motor/module.

The roof opening panel also incorporates a bounce back feature. The bounce back feature is an automatic reversal of the roof opening panel motor if an obstruction is encountered during closing of the roof opening panel glass. The PCM sends a vehicle speed signal to the roof opening panel motor. The roof opening panel motor can then account for the vehicle speed and compensate how the roof opening panel glass bounces back while the vehicle is in motion.
