PRINCIPLES OF OPERATION
Crash Sensing
Impact s ensor
The impact s ens ors are i nst all ed in the front and both si des of the vehicle. W hen the i gni ti on is swi tched on t he Res trai ntsControl Module (RCM), s uppli es power to t he i mpact s ensors which perform a s elf t es t. After s ati sfact ory sel f tes t theimpact s ens ors cont inually out put 'digi tal accelerat ion' mes s ages t o t he res t raint s cont rol module. The us e of mult ipl eimpact s ens ors provide s hort er ai r bag trigger ti mes t hrough fas t er det ect ion of l ateral and l ongit udinal accelerat ion andals o i mproves detecti on accuracy.
Each impact sens or incorporat es an acceleromet er and a mi crochi p powered by a feed from the res traints cont rol module.Accelerati on is evaluat ed by the microchip and t rans mi tt ed t o the res traints cont rol module, which t hen makes the decis ionon whether or not to act ivate the ai r bags and pretens ioners .
If a fault is detect ed the relevant impact sens or sends a fault mes s age, i ns t ead of the di gi tal accel erati on mes s age, t ot he res traint s cont rol module. The RCM t hen s tores a rel ated fault code and il luminat es the ai r bag warning indicator.Faul ts can be ret rieved by t he Land Rover approved diagnos t ic s ys tem from t he RCM via t he high-s peed CAN.
Occupant Monitoring
There are t wo t ypes of occupant monit oring s ys tems fi tt ed to vehi cl es:
1. NAS market s , have an O ccupant Classification Sensing System.1.
2. Markets except NAS and Aust ral ia, have an Occupant Detection Sensing System.2.
1. Occupant Classification Sensing System
A key-operat ed pass enger ai r bag di s abl e s wit ch is ins tall ed in specified market s . When t he pass enger ai r bag deacti vat ions wit ch is operat ed, it changes a ground connect ion bet ween two pins i n the connect ors of t he RCM. A t ell -t ale warningli ght , located in t he roof consol e near t he i nt eri or rear vi ew mirror is i ll uminated when the pas s enger air bag i s dis abled.
The pass enger ai r bag dis abl e s wit ch is operat ed by t he emergency key locat ed i n t he remot e cont rol .
Passenger Air Bag Deactivation Indicator
W hen t he pas senger ai r bag deact ivati on s wit ch is s elected to O FF, t he RCM dis ables t he pas senger ai r bag and if t hefront pas s enger s eat is occupi ed, i ll uminates t he pas senger ai r bag deact ivati on indicator.
Side Air Bags
A s i de air bag is at t ached t o t he out s ide of each front seat backrest frame, under the backres t cover.
The s ide ai r bags are handed and each cons i st s of a mol ded plas ti c cas e whi ch cont ains t he fol ded ai r bag and the infl ator.A cable connect s t he ignit er of t he i nflat or to a connector in the main s eat harness connect or block locat ed under the frontedge of the s eat cus hion.
