CAUTION: The TPMS i s not intended as a replacement for regular t ire pres s ure and t ire condi ti on checks and s houldbe cons i dered as addit ional t o good t ire maint enance pract ices.
The TPMS meas ures t he pres s ure i n each of t he t ires on t he vehi cl e (incl uding t he s pare, if required) and is s ues warningst o the driver if any of t he pres s ures devi ate from defi ned tol erances .
• NOTE: Duri ng a 'bl ow-out ' a very rapi d reducti on in pres sure is experi enced. The sys t em i s not intended t o warn thedri ver of a 'blow-out ', s ince i t is not poss i bl e t o give t he driver suffi ci ent warning t hat such an event is occurri ng, due t o i tss hort durat ion. The des ign of t he TPMS i s t o ass i st t he driver in keeping t he ti res at t he correct pres s ure, which wi ll t endt o reduce the likeli hood of a ti re 'blow-out ' occurring.

The cont rol ling software for t he TPMS i s located wi thi n t he CJB. The s oft ware det ects t he fol lowing:
t he ti re press ure is bel ow t he recommended low pres sure value - under infl ated t iret he pos i ti on of the t ire on t he vehi cle.
The s ys t em compri s es a Radio Frequency (RF) receiver, 4 init iat ors and 4 ti re press ure s ens ors (5 if t he spare wheel has as ens or fi tt ed).
The 4 i nit iators are hard wi red t o t he CJB. The i nit iators t rans mit 125 KHz Low Frequency (LF) s ignals t o t he t ire pres s ures ens ors which res pond by modifying t he mode s t at us wi thin the RF trans mi s si on. 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:
one or more new t ire pres sure s ensors have been fit t edone or more ti re press ure s ens ors have s t opped t rans mi tt ingTPMS s oft ware can reject identi fi cat ions from ti re press ure sens ors whi ch do not belong to the vehiclet he spare wheel and one of t he 'runni ng' wheels on the vehicle have changed pos it ions .
If a new t ire pres s ure s ensor i s fi tt ed on any 'running' wheel , the s oft ware can learn t he new s ens or i dent ificati onautomat ically when the vehicle is driven for more t han 15 mi nut es at a s peed of more than 20 km/h (12.5 mph).
• 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:
Front LHFront RHRear RHRear LH.
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 .
The warni ng appears in t he i ns t rument clus ter mes s age cent re when the i nfl at ion press ure has fal len t o 25% of t henominal pres s ure. The dis played mes sage wi ll als o i ncl ude the pos it ion(s) of t he affect ed wheel(s).
The TPMS enters 'Parki ng Mode' aft er the vehicl e s peed has been l es s t han 20 km/h (12.5 mph) for 15 minut es . In parkingmode t he t ire pres sure s ensors transmit a coded RF s ignal once every 13 hours. If t he ti re pres sure decreas es by more

Four i nit iators are fi tt ed t o the vehicl e. The front i ni ti ators are l ocat ed near t he front of the front wheel arches , behind t hefender s pl ash shi elds . The rear init iat ors are located at t he rear of t he rear wheel arches , behind t he fender spl ash shi el ds.Each init iat or has a connect or which connects to the vehicle body harnes s .
The ini ti at or is a pass ive, LF t rans mit ter. The init iat ors t rans mi t their s ignals which are recei ved by the ti re press ures ens ors , prompt ing them to modi fy their mode st atus .

Tire Pressure Sensor
The TPMS us es act ive t ire pres s ure s ens ors whi ch are l ocat ed on each wheel , ins ide the ti re cavit y. The sens or incorporat est he ti re val ve and is s ecured in the wheel by a nut on t he outs i de of the wheel. The s ensor contains a Pri nt ed Ci rcuit Board(PCB) whi ch hous es a Pos it ive Temperat ure Co-efficient (PTC) s ens or, a Piezo pres s ure s ens or. a radi o receiver andt ransmit ter and a l it hium bat t ery.
The t ire pres sure s ensors use the PTC sens or and the Pi ezo sens or to periodically measure t he pres sure and t emperatureof the ai r ins ide t he t ire. The dat a is trans mi tt ed by RF dat a s ignals at ei ther 315 MHz or 433 MHz dependant on marketrequirements .
The RF t rans mis s ion from t he sens or cont ai ns a unique i dent ificati on code in i ts trans mi ss i on dat a. This all ows t he TPMSt o identi fy the wheel on t he vehi cl e. If t he s ens or is replaced on a 'running' wheel, t he new s ens or i dent ificati on wil l belearnt when the vehicle is driven at s peed of more t han 20 km/h (12.5 mph) for 15 minutes .
If a new s ensor i s fi tt ed t o t he spare wheel, t he identi fi cat ion for that s ens or can be programmed int o t he TPMS usi ng IDS.The code is provi ded on a l abel wit h t he complet e ti re, wheel and sens or ass embly when new and is al s o pri nted on t hecas i ng of each s ensor. Alt ernati vel y, t he s pare wheel may al so be programmed to the TPMS by us i ng it as a 'running' wheelfor 15 minutes at a speed of more t han 20 km/h (12.5 mph), t hen replacing it t o t he spare wheel l ocat ion.
The t ire pres sure s ensor can als o det ect when t he wheel i s rot ati ng. In order t o preserve bat t ery power, t he s ens or us esdifferent t rans mis s ion rates when the wheel is st ati onary or moving. The wheel s peed required to change from st ati onaryt o moving t rans mis s ion rates is very low t o al low for the requi rement for sl ow off-road dri ving.

The care point s detai led i n 'Tire Changing' earlier i n t hi s s ect ion must be foll owed to avoi d damage to the sens or. If a news ens or is fi tt ed, a new nut, s eal and was her mus t als o be fit ted and the s ensor nut t ightened t o t he correct torque asgiven i n the Service Repai r Manual .
