•Failure turn of glass lid while driving rough road.
Glass lid has auto-reverse function. When applied above specified force 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
tilt down/slide open/slide close. (When more than 5 seconds pass, the position detecting function is can-
celled.)
5) Initialize operation is completed.
Symptom Inspection order
Wa t er l e ak ag e 1 . Che ck r o o f p a ne l a n d g la ss li d fo r i mp r o pe r or p oo r se al i ng .
2. Check drain tube for clogging.
3. Check sunroof frame seal and body for improper fit.
Booming noise, wind noise and other noise 1. Check glass lid and roof panel for improper clearance.
2. Check sunshade and roof trim for improper clearance.
Abnormal motor noise 1. Check installing part of motor for looseness.
2. Check gears and bearings for wear.
3. Check cable for wear.
4. Check cable pipe for deformities.
Fai l ur e of su n r oo f
(Motor operates properly.)
1. Check guide rail for foreign particles.
2. Check guide rail for improper installation.
3. Check parts for mutual interference.
4. Check cable slider for improper clinching.
5. Check cable for improper installation.
Motor does not rotate or rotate improperly. 1. Check fuse for blown out.
2. Check switch for improper function.
3. Check motor for incorrect terminal voltage.
4. Check the relay for improper operation.
5. Check poor grounding system.
6. Check harness for open or short and terminals for poor connections.
