The RF receiver is connect edt o the CJB on the Local Interconnect Net work (LIN) bus . The received RF s i gnals from t he t ire pres s ure s ensors are pas s edt o the CJB on the LIN bus and contain identi fi cat ion, pres sure, temperat ure and accel erat ion i nformat ion for each wheeland t ire.

Thi s feat ureis required because of the di fferent pres sure t argets and t hres hold bet ween the front and rear t ires.
The wheel l ocat ion i s performed aut omati cal ly by t he TPMS s oft ware us i ng an 'auto-locati on' funct ion. Thi s functi on is full yautomat ic and requi res no i nput from t he dri ver. The TPMS software automat icall y re-learns t he pos it ion of t he wheel s ont he vehi cl e if t he t ire pres s ure s ensors are replaced or the wheel posi ti ons on t he vehi cl e are changed.

TPMS Operation

The LF si gnal i s received by t he ti re pres sure s ens or which responds by t rans mit ti ng a 315 or 433MHZ (depending on market ) si gnal whi ch is received by t he RF recei ver. The si gnal contains coded data which corres pondst o s ens or identi fi cat ion, air pres s ure, air t emperature and accel erati on data. This i s t hen pas s ed to the CJB on the ISO9141 K Line.
If the vehicle has been parked for more than 15 minutes and t hen dri ven at a s peed of more t han 12.5 mph (20 km/h), t heini ti at ors each fire an LF s ignal in turn for 18 s econds i n t he fol lowing order:

This proces s is repeat ed up t o t hree t imes but l ess if t he s ens or pos i ti ons are already known. The processis known as 'Auto Locati on' and t akes 2 to 4 mi nut es t o compl ete.
