The 315 or 433 MHZ RF s ignals aredetected by the RF recei ver whi ch is l ocat ed at the rear of t he vehicle, behi nd t he headl ining. 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.
The TPMS s oft ware communi cat es wit h t he ins trument cl ust er via t he medium s peed Control ler Area Net work (CAN) bus toprovide t he driver wit h appropri at e warnings. The TPMS s oftware als o i ndi cat es s tat us or fail ure of t he TPMS orcomponents .
Tire Location and Identification
The TPMS can identi fy the pos it ion of t he wheel s on t he vehi cle and as s ign a recei ved ti re press ure s ens or identi fi cat ion t oa s peci fi c posi ti on on t he vehi cl e, for exampl e FL (front l eft ), FR (front ri ght ), RL (rear left ) and RR (rear right). 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.
The TPMS s oft ware can aut omat icall y detect, under all operati ng condit ions , the following:

• NOTE: The s pare wheel is not fit ted wit h a t ire pres s ure s ens or.
TPMS Operation
Each ti me t he vehi cl e i s dri ven the TPMS s oft ware act ivates each i ni ti ator i n turn to t rans mit a LF 125 KHz s ignal t o eacht ire pres sure s ensor. 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:

Each ti re press ure s ens or res ponds i n t urn whi ch allows the TPMS s oftware to est ablis h the s ensor pos it ions at t he st art oft he drive cycle. 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.
Duri ng thi s peri od the t ire pres s ure sens ors t rans mi t at regular int ervals , once every 5 s econds (once every 15 s econds onNAS vehicles ). For the remainder of the drive cycl e t he t ire pres sure s ensors transmit once every 60 s econds or more oft enif a change of ti re pres sure is sens ed unti l the vehicle st ops and the TPMS ret urns t o t he parking mode.
Once the wheel pos it ions have been es t abl is hed, t he i ni ti ators s top t rans mit t ing t he LF s ignal and do not t rans mi t agai nunti l the vehicle has been parked for more than 15 minutes .

T he T errain Response control module and rotary control should only be investigated if there are no apparent faultsin any of the sub-systems. If a fault in a sub-system is subsequently corrected, the T errain Response system willfunction normally after an ignition mode 1 and 2 (on and off) cycle.

It is not possible for the T errain R esponse control module to cause any fault behavior (w arning indicator illuminationor message generation) in any of the 4 sub-systems.
