t he fan mot ors . The fan cont rol module confi rms the fan s peed operati on on the same connect ion back t o t he ECM.
Starter Motor Relay
The s tarter mot or relay i s located in t he BJB. The operat ion of t he s tarter mot or relay i s cont rol led by t he ECM whi chprovides a ground pat h for the relay coil , energi zing t he rel ay and cl osi ng t he relay contact s. W hen the relay contacts areclos ed, bat tery vol tage i s s uppl ied, vi a t he s tarter mot or relay, to the st art er modul e s olenoid coil . The st art er s ol enoi d isenergized and connects the s t art er motor wit h a direct batt ery feed t o operate the st art er motor.
Once the engi ne has st art ed, the ECM removes the st art er motor relay ground, opening the relay contacts and t erminati ngt he bat t ery feed to the s t art er s olenoid, which i n t urn s t ops the operat ion of t he starter mot or.For addit ional informat ion, refer t o: Starti ng Sys t em - 3.2L (303-06, Des cript ion and Operat ion).
Fuel Pump Module
The fuel pump i s cont rol led by t he FPDM whi ch in t urn is control led by the ECM. The FPDM provi des pos it ive and negati vefeeds t o t he fuel pump mot or which is cont roll ed wit h a PW M out put . The fuel pump i s run for 2 s econds t o prime the fuels ys t em once igni ti on on is sens ed by t he ECM.For addit ional informat ion, refer t o: Fuel Tank and Lines (310-01, Des cri pt ion and Operati on).
Malfunction Indicator Lamp (MIL)
The MIL is locat ed in the ins trument cl us t er and is i lluminated by a CAN mes s age from t he ECM when an emis s ion relatedfaul t occurs . The ECM als o ill uminat es the MIL when reques t ed to do s o by t he TCM and t o perform a bulb check when theignit ion is s wi tched on. There is no MIL ill uminat ion for non emis si on rel ated engine management fault s . All engine faul tsare recorded wit h a Diagnos t ic Troubl e Code (DTC) whi ch can be ret rieved us ing a Land Rover approved di agnos ti c s yst em.For addit ional informat ion, refer t o: Electroni c Engi ne Controls - 3.2L (303-14, Diagnos is and Tes ti ng).
Generator Feedback Signal
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.
