This has been achi eved by the ATC (automat ic t emperat ure control) module monit oring and varyi ng, as necess ary variousclimate control funct ions wi thi n a St op/Start cycle.
In s ome circums t ances t he ATC has t he capabil it y to inhibit an engi ne s hut down or init iat e an engine rest art wit hi n aStop/St art cycle. Thi s i s achi eved by t he ATC module communi cat ing wit h t he CJB on the medi um s peed CAN. The variousoverri de functi ons the ATC has in a St op/St art cycl e are di s cus s ed bel ow:

The variant of cli mate control fi tt ed t o the vehicl e influences t he s oft ware changes that have been made. For exampl e, thebase cl imat e-control s ys tem does not have a humi dit y s ens or, as us ed on a highline sys tem t o ini ti at e a winds hi elddemis t . Therefore, a calculat ion for demis ti ng the winds hi eld i s made us ing t he s ignals from t he rai n s ens or and ambientt emperature s ens or.

OVERVIEW
Two l evels of parki ng aid sys tem can be fit ted; a rear only sys t em or a front and rear s yst em.
The parking ai d s yst em provi des an audi ble warning t o t he dri ver when any obs tacles are in the pat h of the vehicle duringforward (i f front s ensors are fi tt ed) or revers e parking manoeuvres . The sys tem consi st s of four ult ras onic s ensors in eachbumper, a parki ng aid modul e and a parki ng aid s wi tch.
At low s peeds , the parki ng aid modul e us es the ul trasonic sens ors t o moni tor t he area around t he front and rear bumpers .If an object i s detected wit hin a monit ored area, t he module t hen outputs a warni ng usi ng t he audi o s ys t em s peakers. Thes ens ors can det ect s oli d objects such as pos ts , wall s and other vehicles and can also det ect l es s s oli d objects such as awire mes h fence. Object s very clos e t o t he ground may not be det ect ed, but becaus e of t hei r low hei ght may not causedamage to the vehicle.
The parking ai d s yst em compris es the foll owing component s:
Parking ai d moduleParking ai d s wit chEight parking ai d s ens ors.
The parking ai d module communi cat es via t he medium s peed Cont roll er Area Net work (CAN) bus wit h t he audi o s yst em vi at he Int egrated Cont rol Modul e (ICM). The audi o s yst em then output s t he appl icabl e warni ng t ones from the front or rears peakers when an object is detect ed. The medi um s peed CAN bus is al s o us ed to col lect vehicle dat a from other vehi cles ys t ems .
Parking Aid Module
The parking ai d module is l ocat ed on the Left Hand (LH) s ide of t he l uggage compart ment , behind t he 'C' pil lar trim panel .
The parking ai d module has t hree connect ors whi ch provide for power, ground and CAN bus connecti ons , front parking ai ds ens ors and rear parking ai d s ens ors .
The medium s peed CAN bus connect ions provi de for t he receipt of the foll owing i nformat ion from ot her s ys tems :
Anti -l ock Brake Sys t em (ABS) modul e - Road s peed si gnalTrans mis s ion Cont rol Modul e (TCM) - Reverse gear engaged si gnalTrai ler module - Trailer at tached to vehicl eIns t rument clus ter - Ambi ent t emperat ure s ignal.
The module al so out puts mess ages on t he medium speed CAN bus whi ch are recei ved by the Int egrated Control Modul e(ICM). The ICM proces s es t hes e mes s ages and convert s t hem int o Media Ori ent ated Sys tem Trans port (MOST) s i gnal swhich are pass ed t o t he audi o s yst em power ampl ifi er. These s ignal s are then us ed by t he power ampl ifier t o emit theappl icable warning t ones from t he front or rear audi o s peakers when an object i s detected by the front or rear parki ng aids ens ors . A warning t one can als o be emi tt ed t o alert the driver to a faul t in the parki ng aid s ys tem.
The parking ai d module performs s elf check rout ines and when t he s yst em is acti ve checks the sens or wiring for short oropen ci rcuit s . If a fault i s detected a code i s s tored in a memory in the modul e and if neces s ary ei ther t he front and/or rears ens ors can be dis abl ed. The driver is made aware of any faul t condit ion by the parki ng aid s wi tch Light Emi tt ing Di ode(LED) flas hing and a conti nuous warning t one bei ng emi tt ed for 3 seconds , in place of the normal short tones when t hes ys t em i s functi oning normal ly. Faul t codes can be read usi ng t he Int egrated Di agnost ic Syst em (IDS) vi a t he diagnost ics ocket.
Parking Aid Sensors
Four ul trasonic sens ors are located i n t he front and rear bumpers . Each s ens or compri s es a s ens or and a bumper ins ert .The ins ert ens ures t hat each s ensor i s correctl y ori entat ed in relat ion t o i ts l ocation i n t he bumper.
Each sens or has a three pin connect or which mat es wit h a bumper harnes s, whi ch in t urn is connect ed to the main bodyharnes s. Three pi ns provide for power s upply, ground and s ignal lines t o and from the parki ng aid modul e.
Each sens or compris es a pl as t ic hous ing which contai ns a piezo elect ric di s c. The disc res onat es at a frequency of 34.8kHz,produci ng t he ult ras oni c output. The di sc al s o receives t he reflected echo s ignal from any objects wit hi n range.
The parking ai d module controls t he operat ion of each sens or usi ng a digi tal output on t he s ignal line. The module controlst he sens or in one of t wo modes ; combi ned transmit ter and receiver mode or receiver mode only.
