Pinpoint Test E : The Roof Opening Panel Does Not Open, Close Or Vent: Notes

Refer to Roof Opening Panel for schematic and connector information.

Normal Operation and Fault Conditions 

The roof opening panel motor receives battery voltage at all times from BCM fuse F27 (30A), and receives ignition voltage (accessory delay) from BCM fuse F23 (10A). The roof opening panel motor and switch are grounded at G302 and G301. When the roof opening panel open switch is pressed, a ground signal is sent to the roof opening panel motor on the roof opening panel open circuit. When the roof opening panel close switch is pressed, a ground signal is sent to the roof opening panel motor on the roof opening panel close circuit. When the roof opening panel tilt switch is pressed, a ground signal is sent to the roof opening panel motor on the tilt/vent switch circuit. The motor responds to these signals dependent on the sliding glass panel and shield positions. One touch operation is accomplished by pressing any of the switches for less than 1 second. For more information on the operation, REFER to: Roof Opening Panel - System Operation and Component Description .

There is a communication circuit between the shield motor (sunshade) and the roof opening panel motor for back and fourth communication between the 2 motors only, and not for diagnostics. If the communication circuit between the roof opening panel motor and shield motor is open or shorted the roof opening panel motor will operate only to fully close the sliding glass, and the shield motor will not operate at all.
