2. Sunroof Control System
A: WIRING DIAGRAM
B: INSPECTION
• Failure turn of glass lid while driving rough road.
Glass lid has auto-reverse function. When specified or more force is applied to the glass lid, the lid turns back
and stops. When operating the glass lid (open or close) while driving the rough road, the lid judges vibration
as a force and may causes failure turns. When the failure turn is occurred, need to perform the initialize op-
eration with following procedure.
1. INITIALIZE OPERATION
1) Tilt up the glass lid.
2) Release the switch once, and press the tilt up switch again for 15 seconds.
3) When the glass lid is raised a little and returned to tilt up position, release the switch for the moment. (Ini-
tialization of position detecting function)
4) Holding down the tilt up switch again within 5 seconds from releasing the switch will automatically perform
the tilt down → slide open → slide close operation. (When 5 seconds or more pass, the position detecting
function is cancelled.)
5) Initialize operation is completed.
