On recei vi ng a reques t for aut omat ic winds hi eld wi per operat ion, t he CJB int erpret s LIN bus mess ages received from therai n s ens or. The rain sens or provides LIN bus mess ages wit h values rangi ng from 0 to 7. A s ignal val ue of 0 is interpretedby t he CJB as there being no wat er on the windshi eld.

Windshield Wiper Park
The winds hield wiper park s wi tch i s int egral wit h t he winds hi eld wiper motor. The park s wit ch ensures the windshi el dwipers ret urn t o t he park pos it ion if t he winds hi eld wiper reques t i s cancell ed mid-s troke.
The CJB is connect ed t o one s ide of t he park s wit ch. The park s wit ch cont act s are open when the wi pers are in any pos it ionexcept t he park pos it ion.

The CJB wil l als o power the rear screen wiper motor i f revers e gear is s elected whi le the wi nds hiel d wi per funct ion i sact ive. On vehicles fit t ed wit h an aut omat ic trans mi s si on, t he reverse gear s ignal origi nat es in the Transmis si on ControlModule (TCM). The TCM broadcas ts a revers e gear s ignal over the hi gh s peed CAN bus to the CJB, which responds byoperati ng t he rear wiper.
On vehicles fit ted wit h a manual transmis s ion, the revers e gear s i gnal ori ginates at t he revers e gear s wit ch. The reversegear s wi tch i s hardwired t o t he CJB.
