W hen t he parking ai d module act ivates t he s yst em, t he s wit ch LED is i ll uminated and a s ingle tone i s emit ted from t hefront and rear audi o s peakers to indicate that the sys tem is operati ng. The parki ng aid module then proces s es si gnal sreceived from the s ens ors t o determine if t here is an object wit h t he det ecti on range of the sens ors .
In the combi ned mode, t he s ensors emit a s eries of ult ras onic i mpuls es and t hen swi tch t o recei ver mode t o recei ve theecho refl ect ed by an obs tacle wit hin t he detecti on range. The received echo si gnal s are amplified and converted from ananal ogue si gnal t o a di git al s i gnal by t he s ens or. The di gi tal s ignal is pas s ed to the parki ng aid modul e and compared wi thpre-programmed dat a s t ored i n an EEPRO M wi thin the modul e.

In receiver mode, t he s ensor receives i mpuls es that were emit t ed by adjacent s ensors. The modul e us es thi s informat iont o precis ely det ermi ne the pos it ion and di s tance of the object .
If no object s are detected t here are no furt her warning t ones . If an object is detect ed, repeat ed audi ble t ones are emi tt edfrom ei ther t he front or rear audio s peakers as appropriate. The t ime delay between t he t ones decreas es as the di s tancebetween t he object and the vehicle decreas es , unt il at approximat ely 250 mm (10 inches), t he audi bl e t one becomescont inuous.

The s ys t em can detect when a t rai ler is connect ed t o t he vehi cl e by a mess age output on t he medium s peed CAN bus fromt he trailer module. W hen the parki ng aid modul e detects that a t rai ler is connect ed t o the vehicl e, t he rear s ensors aredis abled t o prevent cons tant warni ngs due to the cl os e proxi mit y of t he trail er.
