The generator has a Local Interconnect Net work (LIN) bus connect ion direct to t he ECM. The LIN bus is us ed by t he ECM t oreques t vol tage for bat tery charging and t o monit or the fault s t at us of t he generat or.
PRINCIPLES OF OPERATION
Starting Process
The ECM wi ll only al low engine crank, s park and i njector functi ons when the foll owing condi ti ons are met:
A hardwi red Park/Neutral si gnal i s received from the Trans mi ss i on Cont rol Module (TCM)A hardwi red ignit ion s ignal is recei ved from t he CJBA hardwi red crank reques t s ignal is recei ved from t he CJBEncrypt ed data exchange bet ween t he ins trument cl ust er and the ECM is verifi ed.
Before the CJB will s end t he hardwired igni ti on si gnal , it mus t s ati s factori ly complet e t he fol lowi ng:
Exchange encrypt ed data wit h t he s tart control modul e t o vali dat e t he remot e handset.
Addit ional ly, before the CJB will s end t he hardwired crank reques t s ignal i t mus t receive t he fol lowing si gnal s:
Brake s ignal from t he s peed cont rol inhibi t s wit chHardwi red t rans mis s ion in Park (P) or Neutral (N) s ignal from t he s elector lever assembl y.
W i th the remote hands et ins ert ed in the s t art cont rol module and the st op/s tart button is press ed, the st art controlmodule i s sues bat tery vol tage hi gh si gnal on t he LIN bus connecti on to the CJB and the fuel pump i s run for 2 s econds t opri me t he fuel s yst em. The CJB us es this si gnal t oget her wit h t he s top l amp s wit ch signal and is sues a crank requestmes s age on the hi gh s peed CAN bus to the ECM.
The ECM, on receipt of t he crank request mess age, then provides a power and ground supply t o t he s tarter rel ay in theBJB, clos ing the relay contacts . Batt ery volt age is suppli ed via a fus e t hrough t he st art er rel ay and is pas sed to the s t art ermot or s olenoid coi l. The coil is energi zed, clos ing t he s olenoid contacts and allowing a fuse bat tery volt age supply di rectfrom the bat tery to operat e t he s tarter mot or and crank the engine and si mult aneous ly s wi tch t he fuel pump on.
The ECM operat es the st art er motor unti l the engine st art s which i s determined by t he engine s peed exceeding apre-det ermined value.
Auto St art
The ECM has an aut o s tart functi on which all ows the engi ne to cont inue cranking i f the s t op/s tart but ton is released. Thes tarter mot or will operat e unti l the engine st art s or a pre-determined peri od of ti me has el aps ed which i s bas ed on engi necool ant t emperat ure. Low engine cool ant temperat ures al low l onger crank t imes . If the engine does not rot ate or t heengi ne s peed is l ow, the ECM removes t he power s upply and ground from t he st art er rel ay st oppi ng t he crank process .
Start Prevent ion
Operat ion of t he s tart er mot or wi ll not be all owed or wil l be int errupt ed if:
t he engi ne is runni ng and t he engi ne s peed has exceeded a predet ermined s peedt he encrypt ed data exchange bet ween the i nst rument clus t er, ECM, CJB and st art control modul e has fai led t oidenti fy the remote hands ett he gear s elector l ever is not i n t he park 'P' or neutral 'N' pos it ion. The s ignal is det ermi ned from a si gnal from theTCM and al so the t rans mi ss ion mount ed pos it ion s wit cht he brake pedal i s not pres sed.
Engine Stop Process

To s top the engine t he s t op/s tart but ton must be pres sed. Forcibly removing t he remote hands et from t he s tart controlmodule will not s top the engine. On models wit h automat ic t rans mi ss i on, once the engi ne has st opped the remotehands et wil l not be releas ed by t he s tart cont rol module unt il the trans mi s si on s el ect or lever is i n t he Park (P) pos i ti on.
Throttle Control
The ECM controls t he posi ti oni ng of the throt t le di sc i n t he electric t hrot tl e us ing i nformat ion from t he APP s ens or and t heTP s ensor. Dat a from t he A/C pres sure s ens or, TCM, ECT s ens or, MAF s ensor and t he MAP/IAT s ensor i s als o us ed todetermine t he correct t hrot tl e cont rol .
The t wo Hall effect sens ors i n t he TP s ens or are des ignat ed 1 and 2. Both sens ors out put an i ncreasi ng vol tage as thet hrott le di s c angl e increas es. Smal l air fl ows t hrough the throt tl e requi re comprehens ive regul at ion, t herefore the vol tageri s e in one of the s ensors increas es more quickl y t han the ot her s ens or whi ch gives accurat e cont rol of t he thrott le andensure t he thrott le di sc is i n t he correct posi ti on.
The ECM moni tors the si gnal s from bot h s ens ors to ens ure they are wit hin the minimum and maximum t hres hol ds and thatt he si gnal s corres pond t o the same thrott le di sc pos it ion. If there is a difference in the si gnal s the ECM us es a defaultt hrott le si gnal calculated from t he electric t hrot tl e load, engi ne s peed and ai r pres s ure and t emperature s ignals . Thes ens or whose out put s ignal i s clos est t o t he calcul ated t hrot tl e dis c angle will be us ed as t he correct output . A faul t codewil l be recorded for the ot her s ens or and t his can be read us ing a Land Rover approved di agnos ti c s ys t em. The ECM t henmonit ors t he remaining s ens or out put s i gnal and compares it agains t t he cal cul ated value. If a difference i n thecomparis on occurs t he ECM wi ll dis count t he output from bot h s ens ors and dis abl e t he electric t hrot tl e cont rol and revert toa l imp home mode. The throt t le di sc has s prings for opening and clos ing and t he ECM can meas ure the l oad appl ied byt hes e s pri ngs for a l oad s ignal . If a fault occurs whi ch prevent s t he damper mot or from being operat ed, the s prings ret urnt he throt t le di sc to a pos i ti on which all ows a t hrot tl e openi ng large enough t o all ow t he vehi cle t o driven, but wi th reduceddri ve abi li ty.
Throt tl e Adapt ions
The ECM has a learning adapti on which al lows t he ECM t o calculate the preci s e cont rol required for t he elect ric throt t ledamper motor. The adapti on process is performed when the ignit ion i s on and t he engine is not runni ng. The t hrot tl e dis cis moved by the damper mot or to t he fully cl osed pos it ion and t he ECM records t he val ues out put by the TP sens orpotenti ometers.
If the permanent batt ery supply t o t he ECM has been removed, t hen previous adapt ions wi ll have been los t. If adapt ionsare st ored, t hen the ECM compares the s t ored adapti on val ues wit h t he current t hrottle angl e and us es an average of thes tored and current values t o create the new adapt ion value.
If the el ect ri c throt t le unit has been repl aced, t he power s upply mus t be removed from t he ECM t o eras e al l previousl ys tored adapt ion values .
Fuel Pressure Regulation
Fuel pres s ure regulati on is cont roll ed by t he ECM t o res pond t o fuel pres s ure demand and provi des s t epl ess cont rol of the
pump output us ing t he FPDM t o control t he pump operat ion. The ECM can vary t he fuel pres s ure to bet ween 55.1 l bf/in2
(3.8 bar) and 72.5 lbf/i n2 (5 bar). The hi gh pres s ure i s only us ed in ext reme condit ions s uch as heavy engine loads andengi ne s tarts .
The ECM us es t he si gnal s from the fuel rail pres s ure/temperat ure s ens or t o det ermi ne informat ion regardi ng t he pres sureand t emperature of the fuel and provi de precis e i njecti on periods , improvi ng engi ne s tarti ng under all condit ions. Theadvant age of controll ing t he fuel pump output pres s ure are t hat pump power consumpt ion is reduced, loweri ng the load ont he power s upply s yst em and reduci ng fuel cons umpt ion, improved s ervi ce life of t he pump and reduced fuel pump nois e.
• NOTE: W hen t he i gni ti on is swi tched off t he FPDM reduces t he fuel li ne pres s ure regul at ion to 29 lbf/in2 (2 bar) to hel preduce inject or leakage.
Knock Control
Knock occurs i n a cyli nder when t he fuel and air s elf i gni tes at t he wrong ti ming. This can occur eit her before or after t hes park i s produced. The fuel mi xt ure can ignit e in different areas of t he combus t ion chamber and res ul ts in a fas tcombus t ion proces s creati ng s everal s eparat e fuel combus t ions which t oget her combi ne to produce a mechani cal knockings ound. The s ounds produce a certain type of vibrat ion through t he engine cylinder block and thes e are detected by t heknock s ensors . The two knock s ens ors det ect knocks on cyl inders 1, 2 and 3 and 4, 5 and 6 respecti vel y.
The vibrat ions act upon the peizo crys t als wi thi n t he sens ors whi ch res ult s in a volt age bei ng produced whi ch is sens ed byt he ECM. The ECM, us ing the CMP sens ors and t he CKP s ensor, can det ermi ne which cylinder(s ) are knocking. The ECM isable t o fil ter t he s ignal t o det ect vibrat ions creat ed duri ng normal engi ne operati on and dis card t hem from the knockdetecti on. The i gni ti on t imi ng is gradual ly advanced unti l the knocki ng is det ect ed once agai n.
Once the ECM has determined knocking is occurri ng usi ng other input s s uch as cat al yti c convert er temperat ure for exampl ein addi ti on to the s i gnal s from t he knock s ens ors , it first retards the ignit ion t imi ng and s ubs equent ly ri chens t he air/fuel i frequired.
Variable Camshaft Timing (VCT) Control
The inl et cams haft i s cont rol led by t he ECM us ing the VCT s olenoid. The exhaus t camshaft is fixed and i ts ti ming cannotbe changed.
Both cams haft s are dri ven i ndirect ly from the cranks haft via a chai n. The chain is driven from a s haft in the gear hous i ngas sembl y.For addit ional informat ion, refer t o: Engi ne - 3.2L (303-01, Descripti on and Operat ion).The VCT all ows t he ECM t o adus t t he inl et cams haft pos it ion i n rel ati on to the cranks haft , al tering t he t imi ng of theopeni ng and clos ing of t he inlet and exhaus t valves rel ati ve to the cranks haft posi ti on.
