Under t he change, the i nternal elect ronics (print ed circuit board (PCB), motor,etc.) of t he l ock have been removed and t he lock has been dis abled i n t he car configurat ion fi le.

RF RECEIVER
The Radio Frequency (RF) antenna is locat ed i n a central pos it ion behind the head l iner. The receiver is avail able i n t wovariant s; 315 MHz or 433 MHz depending on market requirements . Trans mis s ions are received from the remote hands et forkey identi fi cat ion and remote lock/unlock request s or reques ts for operati on of the addit ional driver convenience feat ures.
PRINCIPLES OF OPERATION
The remot e handset i s validat ed via t he s tart cont rol module and t he CJB. If t he remot e handset i s valid the CJB i nit iatest he unl ocking of t he elect ric st eeri ng col umn lock (if enabled). Once t he electric st eering column lock is unl ocked and powerhas been removed, then t he CJB enabl es the Fuel Pump Dri ver Module (FPDM) on pet rol vehi cl es or the fuel pump relay ondies el vehicles .
The CJB als o control s t he engi ne crank reques t. On vehicl es wit h automat ic t rans mi ssion, i f the t rans mis s ion sel ect or l everis in t he Park 'P' pos it ion and the driver pres ses t he brake pedal or on manual t rans mis s ion vehicles i f the driver pres s est he cl utch pedal and s i mult aneous ly pres s es t he s tart /st op s wit ch, t he CJB i nt erprets t his as an engi ne crank request .Before the engi ne crank request i s all owed, t he CJB checks for t he brake or clut ch swit ch si gnal . If t he s ignal is correctt hen the CJB s ends a crank reques t s ignal t o t he ECM on the hi gh speed Controll er Area Network (CAN) bus .
If a replacement remot e hands et i s required, t hen a Land Rover approved diagnost ic sys tem mus t be us ed to s ynchronizet he remot e hands et s. If any module, which i s involved in the remote hands et aut hori zat ion proces s , require replacement, aLand Rover approved diagnos t ic s ys tem procedure is al s o required t o s ynchronize t he repl acement module into the s ys tem.

Diagnosi s and Tes ti ng
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.
