SUNROOF – CIRCUIT OPERATION

CIRCUIT OPERATION

The sunroof can operate in either slide or tilt mode. To change from one mode to the other, the sunroof must be in the closed position, the switch released and then repressed. The sunroof functions will be active if the ignition is selected or for the first 45 seconds after it has been switched off provided that no door lock signal is received, in which case the timer will be cancelled. The sunroof slide function will operate in one of two modes: one touch, or dead man’s handle. One touch mode is initiated when the sunroof switch is operated for less than 400ms, dead man’s handle mode is initiated when the sunroof switch is operated for 400ms or more. Further operation of either sunroof switch during the one shot mode will cause the sunroof to stop operation. The sunroof tilt function will operate in deadman’s handle mode only. There will be trap detection on sunroof close and on tilt close, but not on opening operations. If a trap is detected whilst the sunroof is closing from the slide position, then the sunroof will back off 20cm or until the motor stalls. If a trap is detected whilst the sunroof is closing from the tilt position then the sunroof will back off to the fully tilt open position. These conditions will also activate a message on the instrument pack which will be accompanied by three audible beeps. With the sunroof in the closed or partially tilted open position, operation of the sunroof forward switch will cause the roof to operate in the tilt open direction. This will continue until the switch is released, or until a stall condition is detected. If the sunroof back switch is operated while the sunroof is in the tilt open position, the roof will operate in the tilt close direction. This will continue until the switch is released, a trap is detected or until the sunroof is in the closed position. If the sunroof back switch is operated with the sunroof in the closed or partially open position, the sunroof will operate in the open direction. This movement will continue until the switch is released (unless in the one touch mode), the sunroof forward switch is operated, or a stall condition is detected. With the sunroof in an open position, operation of the sunroof forward switch will cause the sunroof to operate in the close direction. This will continue until the switch is released (unless in the one touch mode), the sunroof back switch is operated, a trap is

detected, or until the sunroof is in the fully closed position. The heated rear window will be inhibited for the duration of any sunroof operation. Market Deviations: USA/Canada: the system will only be active when the auxiliary or ignition feeds are on, or for the time between switching the ignition feed off and opening either of the front doors. Australia: the system will only be active when the ignition switch is in the auxiliary, the ignition or the crank position, or for 45 seconds after the key is removed from the ignition switch.
