OVERVIEW
The roof openi ng panel i s a double l engt h glas s unit , wit h t he rear half being fi xed i n pos it ion.
The front hal f of the roof opening panel is el ect ri cal ly operat ed through a 2 way rocker s wit ch located i n t he roof cons ole.An elect ric motor, at t ached t o t he rear of the roof opening panel frame, dri ves t he front glas s panel t o t he ti lt , open orclos ed pos i ti on. The gl as s panel is operat ed by 2 cables , which are driven by t he mot or.
Operat ion of t he roof openi ng panel i s cont roll ed by t he roof openi ng panel control unit , which i s int egral wit h t he mot or.The cont rol unit recei ves i nput s from the CJB and t he s wit ch t o cont rol roof opening panel operat ion accordingly. The CJBals o provi des a vehi cl e s peed si gnal t o t he cont rol unit , which i s used to cali brat e the ant i-trap feat ure.
CONTROL UNIT/MOTOR

ItemPart NumberDescription
1-Motor
2-Cont rol unitThe combined cont rol unit and mot or ass embly is mount ed behi nd t he headli ning, to the rear of t he roof opening panel.The cont rol unit us es inputs from t he CJB and t he roof openi ng panel s wit ch to cont rol operati on of the motor.
The end of the motor armat ure is formed as a worm drive, whi ch dri ves a gear at tached to the end of t he mot or as s embly.The gear engages wit h heli xed cables i n t he roof openi ng panel frame to form a rack and pinion drive.
The cont rol unit i ncorporates a Hal l effect s ensor which i s us ed to count t he revolut ions made by t he mot or armature. Bycount ing t he revolut ions t he cont rol unit can accurat ely det ermi ne when t he glas s panel has reached it s ful ly open, cl osedor ti lt pos it ion by compari ng the armat ure rotat ion value agains t values s tored in its memory. The values are st ored in t hecont rol unit 's memory when t he i ni ti alizat ion rout ine has been carried out .
The cont rol unit al so monit ors t he temperature of the mot or and wil l sus pend operation if an overheat s it uat ion is l ikely t ooccur. The t hermal prot ect ion funct ion has 2 levels of operat ion.
Level 1 - The control uni t wil l onl y all ow t he roof openi ng panel t o be clos edLevel 2 - Al l operati on is s us pended except 'Ant i-Trap'.

The roof openi ng panel i s att ached t o t he outs i de of the body s ide panels , the front roof panel and the rear roof panel wi tha Polyuret hane (PU) adhesi ve. The roof panel compris es a pl as t ic one pi ece frame hous i ng 2 glas s panel s .

The rear glas s panel i s fixed in pos i ti on and bonded t o t he roof openi ng panel frame us i ng a PU adhes ive. The forwardglas s panel i s dri ven into pos i ti on by a pair of heli xed cables . The helixed cables are abl e t o pus h or pul l the forward glas spanel i nt o t he requi red pos it ion.
The roof openi ng panel al so cont ai ns 2 i nt egral, manuall y operat ed sunbli nds and 2 drai n hoses . The drai n hoses areconnected t o t he cent er of the frame above t he B pi ll ars . The drain hos es run through the cant rail s and down t he C pi llarst o all ow water coll ect ed in the frame to escape.

PRINCIPLES OF OPERATION
The roof openi ng panel wi ll only operat e when t he vehi cle i s in power mode 6 (i gnit ion on). Power is suppli ed to the roofopeni ng panel cont rol unit /motor by t he CJB, whi ch suppli es bot h a permanent bat tery and ignit ion power s uppl y. The CJBals o provi des a vehi cl e s peed si gnal t o t he cont rol unit .
For det ails on how t o operate the roof opening panel, refer t o t he 'Owners Handbook'.

Switch Inputs
The roof openi ng panel rocker s wit ch is mount ed in the roof cons ol e and i s provided 2 si gnal feeds by t he control unit .W hen t he s wit ch is in t he res t (cent ral ) pos it ion, both connect ions from the cont rol uni t are open ci rcuit . W hen t he swit chis pres sed t o open t he glas s panel , the si gnal feed from pin 4 of t he cont rol unit electrical connect or is provi ded a groundpath through t he s wit ch cont act s . W hen t he s wit ch is pres s ed t o clos e t he glas s panel , the s wi tch grounds t he s ignal feedfrom pi n 8 of t he cont rol unit el ect ri cal connector.
W hen t il t operati on is reques t ed, t he s wit ch grounds the si gnal feed from pi n 8 of the cont rol unit electrical connect or asdescribed for 'cl ose' operati on.
Anti-Trap
The roof openi ng panel mot or is cali brat ed to det ect a blockage t hat wil l prevent t he glas s panel from cl osi ng. The forcerequired t o clos e t he glas s panel on a st ati onary vehi cl e wi ll not exceed approximately 100 Newt ons (N). If t his l imit isreached, t he cont rol unit wi ll power the motor in the oppos it e direct ion t o reverse the pos it ion of t he glas s panel by 200mm.
The cont rol unit al so monit ors external forces which may i ncrease the force requi red t o clos e t he glas s panel . The cont rolunit bas es this fi gure on vehicle speed, rough road condit ions, and ext reme ambi ent ai r temperatures and may increas et he maximum force appl ied by t he mot or t o approximat ely 150 N if requi red.
Vehicle Speed Signal
The vehi cl e s peed s ignal i s us ed by the roof openi ng panel cont rol unit t o adjus t t he s ens it ivi ty of t he anti -t rap feature.This s ignal all ows the control uni t to take i nt o account wi nd res is t ance when clos ing the roof opening panel at vehicl es peeds hi gher t han 2.5 mph (4 kph).
The vehi cl e s peed s ignal originat es in t he ABS modul e, and i s broadcas t over the hi gh s peed CAN bus . The CJB convert st he vehi cl e s peed si gnal i nt o a pul sed vol tage s ignal for deli very t o the cont rol uni t. Thi s s ignal puls es at a rate of 8,000puls es per mil e (5,000 puls es per ki lomet er), and has a dut y cycl e of 50% on 50% off.
Calibration
If the bat tery is di sconnect ed, or t he power s upply i s int errupt ed, whils t t he s unroof is part ial ly open i t wil l need t o berecali brated.
Once the bat tery is reconnected, or the power s uppl y is res tored, recal ibrat e t he s unroof as foll ows:
Swit ch the ignit ion on.W i th the s unroof clos ed, press and releas e t he front of t he s wit ch. The s unroof wi ll move t o t he ti lt ed posi ti onready for cali brat ion.Pres s t he front of t he s unroof s wit ch, and hold for twent y s econds .Aft er twent y s econds t he sunroof wi ll begin t o move. Keep the front of t he s wit ch pres sed unt il t he s unroof hasful ly opened, t hen clos ed.Once the open/cl os e cycle has complet ed and the sunroof has s topped moving, rel eas e the s wi tch.
The s unroof can now be operated as normal.
