Two CPS s olenoids are located at each end of the cyli nder head, adjacent t o t he inlet cams haft and are each s ecured wi tha bolt . The CPS s olenoids s uppl y oil pres s ure t o t he hydrauli c tappet locki ng pins al lowing t he cams haft profile to bechanged. Each s olenoid controls t he oil press ure supply to the hydrauli c tappet locking pins on 3 cyl inders .For addit ional informat ion, refer t o: Engi ne - 3.2L (303-01, Descripti on and Operat ion).
The CPS s olenoids receive a fus ed batt ery s upply via the main relay. The ECM provides a ground for t he s ol enoi d, whichact uates a val ve wit hin t he s olenoid al lowing oi l pres sure t o adjus t the cams haft profil e.
The ECM can diagnose the operat ion of t he CPS s olenoids and s t ore faul t rel at ed codes . The codes can be read us ing aLand Rover approved diagnos t ic s ys tem.
Ignition Coils
Six pl ug top coi ls are used on the i6 engine and are located in reces s es in t he t op of the cyli nder head. The coi ls arecont rol led by t he ECM and recei ve a fus ed, bat t ery volt age s upply vi a t he main rel ay. The ECM controls t he s park t imingand product ion by swit ching the primary circuit of each coil to ground all owing t he charge which has buil t up in the coil t oproduce a s park at t he s park plug.
Each coi l contai ns a power st age which controls t he pri mary current and the ECM s ends a si gnal t o each coi l to operat e t hepower st age s wit chi ng at the appropriate ti me. Each coil has a feedback wi re to t he ECM whi ch all ows the ECM to diagnos eeach individual coi l and st ore fault related codes. The codes can be read us ing a Land Rover approved diagnos t ic s yst em.
A s uppres sor i s mounted on the cams haft cover adjacent to ignit ion coil 3 t o prevent int erference from t he coi ls and/or t heinject ors affecti ng audi o operat ion.
Fuel Injectors
Six fuel injectors are us ed on the i 6 engine and are located on t he i nl et s ide of t he cyl inder head. The inject ors are s eal edin the cyli nder head wi th O -ring s eals and held in pos it ion by the fuel rail .

The posi ti on of the inlet cams haft is det ermi ned by the ECM us ing s ignals from t he CKP s ens or and t he CMP s ens ors. TheECM can t hen use the VCT sol enoid val ve to cont rol t he angl e of the cams haft by controlli ng t he fl ow of oil t o t he VCT unit .
The camshaft is s ecured t o t he rot or in t he VCT unit . Oil pres s ure suppli ed to eit her s ide of t he VCT unit from t he VCTs olenoi d valve can rot ate the rotor and hence the cams haft i n eit her di recti on. The VCT sol enoi d is operat ed by t he ECMus ing PW M, hi gh frequency s wit chi ng which provi des rapid and preci se cont rol of the i nlet cams haft pos i ti on. The i nletcamshaft pos i ti on can be adjust ed wi thi n 40 degrees of cranks haft rotat ion.
Camshaft Profile Switching (CPS) Control
The inl et cams haft has , in addit ion to t he VCT control, a CPS funct ion whi ch is al so cont roll ed by t he ECM. The CPS cont rolcan vary t he val ve li ft height and durat ion of t he camshaft lobes by adjus ti ng the area of t he hydraul ic t appet whi ch act son one of t wo cam l obe profi les . The CPS cont rol is vi a t wo CPS s olenoid valves , located at each end of the i nlet cams haft.The CPS s olenoid valves cont rol t he posi ti on of hydraul ic t appet as s embli es which can be s et in one of t wo pos it ions; lowand high.
Two CPS s olenoids are us ed so that t he hydraul ic t appet s can be adjus t ed when no load i s applied, for example the camlobes are off t he hydraul ic t appet s and t he cam bas e circl e is act ing on t he t appet , thi s keeps t he s tress on components toa minimum. One CPS s ol enoi d s uppl ies oi l press ure to the hydrauli c t appet s of cyli nders 1, 2 and 4 and the s econd CPSs olenoi d s uppl ies oi l press ure to the tappet s of cylinders 3, 5 and 6.
At engi ne s tart and at low engine oi l temperat ures (below 40°C (104°F)) the ECM does not direct engine oi l pres sure t ot he hydraul ic t appet s and t herefore the hydraul ic t appet s are in t heir s pring loaded, l ow posi ti on.For addit ional informat ion, refer t o: Engi ne - 3.2L (303-01, Descripti on and Operat ion).
Ignition Control
The ECM calculat es the opt imum ignit ion ti ming bas ed on pre-programmed maps and informat ion from t he foll owings ens ors :

Once the engi ne has reached i ts normal operati ng temperature, t he ECM moni tors the si gnal s from the knock sens ors . Ifany of the cyli nders produce knocking, the i gnit ion t imi ng for t hat cyli nder wi ll be retarded unt il t he knocking has s t opped.The ignit ion is t hen gradually advanced back t o t he normal t imi ng or unt il t he knocking re-occurs .

Principles of Operation
For a detail ed descripti on of the Pas s ive Ant i-Theft Sys t em (PATS), refer t o t he relevant Des cript ion and Operat ion secti onin the workshop manual.REFER to: Ant i-Theft - Pas s ive (419-01B Anti -Theft - Pas s ive, Descripti on and Operat ion).
Inspection and Verification
The best method t o confirm the correct operat ion of t he Pass i ve Ant i-Theft Syst em (PATS) is t o check t he LED (located i nt he cent er of t he ins t rument panel ). The LED s hould i ll uminate sol id for 3 s econds , when the i gnit ion s tat us is set t o ON,and t hen ext inguis h. Thi s validat es all PATS functi ons (i .e. the key t rans ponder matches a st ored key code, thechal lenge/res ponse sequence bet ween t he res pect ive modules was succes s ful res ult ing in t he EMS being enabled).
Ignition Fails to Operate
Check t hat the key i s correct ly i nserted i nto the s t art cont rol unit (SCU) and that i t is t he correct key for t he vehi cle (Keywil l be ejected from t he SCU i f it is not programmed or from anot her vehicl e). If the vehicle is an aut omati c, ens ure t hatt he Park pos it ion i s s el ect ed and if manual, ens ure it is in t he Neutral pos i ti on.
Check t hat the st art but ton circui t to the Cent ral Juncti on Box (CJB) i s not open circui t or s hort to ground.
Check t hat the CAN network is not mal functi oni ng, i .e. open circuit or s hort circui t. This woul d mean t hat the CJB, ECM andIns t rument Clus t er woul d be unabl e t o communicate. Check thes e modules for relat ed DTCs and refer t o relevant DTCIndex.
Engine Fails to Crank
The immobili zer s t atus i ndi cat ion LED i s dis played i n the bot tom left of the i nst rument pack. W hen the key i s i ns ert ed i nt ot he SCU, t he LED wi ll be t urned on for 3 s econds and t hen turned off. The LED will flas h s lowl y (once every 2 seconds ) i ft he vehi cl e is immobi lis ed (t ransponder not approved). Addit ionall y the di agnos ti c syst em s hould be us ed t o check forDiagnost ic Troubl e Codes (DTCs ) from the CJB, ins trument cl ust er, ECM and the ABS modul e.
One potent ial occurrence for the vehicl e fai ling to crank on an Automat ic Trans mi s sion coul d be due t o t he Locked in parks wit ch.
Check t he Crank reques t circui t from t he CJB t o ECM for short ci rcuit or open circuit .
Check t he St art er Rel ay Circuit .
Check t hat the St eeri ng Col umn Lock (SCL) is operat ing correctl y. Ins erti ng t he key should drive t he SCL t o un-l ock ands teeri ng wheel should move freel y.
Check t he CAN net work i s not malfunct ioning, i.e. the CAN ci rcuit i s open or short ci rcuit . Thi s would mean that t he CJB,ins t rument clus ter, ECM or ABS module would not be abl e t o communicate res ul ti ng in no chal lenge being made from t hemodules for the Immobil is ati on data.
Als o on an Aut omat ic, check the CAN network between t he CJB and the Transmis s ion Control Modul e (TCM). The CJB usest he "LockedInP" s ignal transmit ted by t he TCM to det ermi ne if t he t rans mis s ion i s in Park before all owing crank, the CJBus es a value of 0x01, i f the CJB s ees a value l ess than t his i t wil l not al low crank, and key wil l not be ejected from SCU.
For a manual gearbox t he clut ch pedal has to be de-pres s ed, hence check t he CAN network between t he CJB and t he ECMt o ensure t he cl utch i s depress ed, Clut chPedal Swit ch75pct = TRUE and Cl ut chPedalPress ed2 = True. The Vehicl e wil l notcrank unti l thes e s ignals are s et.
On an Aut omati c vehi cl e, check t he CAN network between t he ABS module and the CJB. The CJB uses a s ignal"BrakePedalActi ve" t o det ermi ne if t he brake pedal has been depres sed in order t o allow t he engine t o crank. The CJB us esa value = TRUE i f the CJB does not receive t hi s s ignal, i t wil l not al low t he crank reques t output.
Engine Cranks But Will Not Start
If the engine i s cranking i t means that t he EMS has pass ed t he authori s at ion required wit h t he CJB. If thi s authori s at ionfai led, the ECM would not engage the s t art er relay. Thi s coul d be confi rmed by verifyi ng t he LED in the l eft of t heIns t rument pack bei ng il lumi nat ed for 3 seconds on Key ins ert ion, or by reading DTCs from t he CJB or t he ECM.
In all cases of s us pected non-st art i s sues , the most l ogical fail ure modes s houl d be el imi nat ed first . i.e.
1. Check al l relevant suppli es and grounds to the relevant modul es are ok.2. Note any unus ual behavi our from other s yst ems /funct ionali ty.3. Note any funct ions t hat are not operati ng as expect ed.
Fault Codes/DTCs
For the vari ous PATS modes of operat ion/fail ures l is ted i n t he t abl e, t he CJB wi ll store a DTC whi ch wil l not be shown t ot he cus t omer.
W hen t he Key i s ins ert ed and ignit ion st atus ON is achieved, if t he s tart aut horis ation pas ses , the LED in t he bott om leftof the ins trument cl us t er will i ll uminate for 3 s econds t hen go off. If st art aut horis ati on fai ls , the LED wil l conti nue to fl as hevery 2 s econds . Pleas e s ee tabl e below for a li s t of fault codes that wil l be s tored under cert ain condi ti ons.
