Gear Neutral Sensor
A PLCD (permanent magnet l inear cont act les s dis placement) s ensor i s located on the exterior of the trans mi s si on cas i ngand hardwired t o t he ECM. The sens or’s functi on is t o det ect t hat neut ral gear has been s elected wi thi n a cali bratedwindow.
No cali brati on is neces sary for t he Gear Neut ral Sensor upon repl acement, i t is however monit ored and a DTC wil l belogged s houl d a fault occur. Fault codes can be diagnos ed us ing Land Rover approved di agnos ti c equi pment.
Linear Clutch Sensor
To ens ure an engine res tart during a St op/St art cycl e does not del ay the get away demands of cit y dri ving, the engine i sres t art ed in approximately 800 mil li seconds . This i s achi eved through t he li near clut ch s ens or triggeri ng an engine rest artwhen t he cl utch pedal is at t he s tart of i ts downward t ravel. So whil e t he dri ver conti nues t o depres s t he clutch t hrought he res t of it s t ravel t he engine rest art i s already i n progress .
The li near clut ch s ens or is a PLCD (permanent magnet li near contactl es s di spl acement) type and i s located on t he clut chmas ter cylinder and hardwired t o t he CJB. The s ensor provi des t he CJB wi th a cont inuous input of the clut ch pedal ’sposi ti on; this informati on is relayed t o t he ECM on t he high-speed CAN bus . The ‘t op of travel ’ si gnal i s used to aut horizean automat ic engine res tart if all ot her s ys tem condit ions are approved.
The li near clut ch s ens or als o provides a ‘bott om of t ravel’ s ignal near t he end of the cl ut ch pedal ’s t ravel. This si gnal i sus ed if t he engi ne s tal ls and i s a requi rement t o authori ze a s tal l recovery. This is unique funct ion t hat allows the enginet o res t art automat ically if all ot her s ys tem condit ions are approved. For addi ti onal i nformat ion refer t o t he Stall Recoverys ect ion, below.
A magnet ins ide the clut ch mas ter cylinder provides t he posi ti on indicator for the linear cl utch s ensor. For t his reason, ift he mas ter cyl inder is replaced the correct replacement mas t er cyli nder mus t be i dent ified and fit t ed.
The t wo exis ti ng clutch pos it ion-s wi tches, l ocat ed on t he cl utch pedal hous ing and us ed as i nput s for vari ous vehi cl es ys t ems , are al so ut il ized by t he Stop/Start sys tem for pl aus ibi lit y checks .
If a fault develops wi th the l inear cl utch s ensor a DTC wil l be logged in the CJB.
• NOTE: The Stop/Start sys tem wil l not funct ion correctl y if t he dri ver rest s t hei r foot on t he clut ch pedal whil e dri vi ng t hevehi cl e.
Brake Vacuum Sensor

To ens ure t he vehi cl e’s braki ng s ys t em i s never compromi sed, a brake vacuum s ens or is int roduced on Stop/St art vehiclest o monit or vacuum reserves in t he brake s ervo. The vacuum sens or is mount ed in the vacuum pipe and hardwi red to t heECM. In the event of brake vacuum decreas ing below a s et threshold during a Stop/St art cycl e t he ECM wi ll s end a s ignalt o eit her:
Rest art t he engine and consequentl y replenis h vacuum reserves .Inhi bi t t he engi ne s hut ti ng down if vacuum res erves are not s uffi ci ent.
An example of vacuum res erves deplet ing, is by t he dri ver repeat edly pres s ing t he brake pedal when the engine iss hut down duri ng a St art/Stop cycle. This acti on wil l init iat e an engine res tart when vacuum reserves decreas e below thes et thres hold.
If a fault develops wi th the brake vacuum s ensor a DTC wil l be logged in the CJB.
Auxiliary Coolant Pump
Duri ng a St op/Start cycle when the engine i s s hutdown and consequent ly the engine-driven coolant pump is st ati onary, thedesi red s et cabi n t emperature cannot be mai ntai ned for a prol onged period, especially in col d ambient t emperatures . Tocount eract this , an auxil iary el ect ri c cool ant -pump has been integrat ed i nt o t he cool ing s ys tem to maint ain t he cool antfl ow t hrough t he cabi n’s heat er core. Thi s s upporti ng ci rculat ion t herefore prol ongs t he s et temperat ure set ti ng in the cabinand accordi ngl y prevents an early engine res tart.
Dependi ng on vehi cl e clas s ifi cat ion the auxil iary coolant pump i s eit her:
Hardwi red di rectl y to the ECM.Or if t he vehicle i s fit ted wi th a FFBH (fuel fi red boos ter heat er), t he FFBH coolant pump i s uti li zed and act ivatedvia t he FFBH.
The functi onal it y of bot h t ypes of auxil iary coolant pump i s t he s ame wi th regards the Stop/St art s ys tem.
To dis guis e t he acti vat ion s ound of the auxil iary pump, t he pump i s acti vat ed at the same ti me as t he engine s huts down.
Remote Handset
To all ow t he dri ver eas e of use, a revis ed remot e handset releas e has been introduced. Thi s all ows t he driver t o ins t ant lyrel eas e t he remote hands et from t he s tart cont rol module when t he engine i s s hut down in a Stop/Start cycle.
The vehi cl e reverts t o t he conventi onal remote hands et releas e when not in a Stop/Start cycle, that i s by pres s ing t heignit ion St art /St op butt on before rel eas i ng the remote hands et.
Stall Recovery
In the event of an engi ne s tal l, t he Stop/St art s ys tem ent ers a unique ‘s t al l recovery’ mode. This feature aut omat ical lyatt empts to res tart the engine as soon as t he driver full y depres ses t he clut ch pedal; t he natural react ion of t he dri verwhen experiencing a s t alled engi ne si tuat ion.
Once the cl utch s ensor detects the ‘bot t om of t ravel’ threshold, refer to ‘Linear Clut ch Sens or’, t he s t arter mot or isact ivat ed to res tart the engine. The warni ng indicat ors normal ly as s oci ated wi th an engi ne s tal l, for example the i gni ti onand low oil pres s ure i ndi cat ors i n t he ins t rument clus ter wil l be s uppress ed s o wi ll not il lumi nat e. The Eco indicator does

however remain i ll uminated.
A ‘st all recovery’ event is the onl y s tat e when t he Stop/St art s yst em wil l permit t he engine t o be s t art ed when thet ransmis s ion i s in gear; hence t he requirement for t he cl utch pedal to be full y depres sed. If the s t all recovery fai ls and t heengi ne does not res tart, t he dri ver wi ll be reques ted vi a t he Mess age Center t o ‘s elect neutral ’ to at t empt anot her rest art .
If the engine does not res t art aft er thi s request t he ‘st all recovery’ mode wil l ti me-out and deact ivate. At t his point t he‘Eco’ i con in t he i ns t rument panel wi ll exti ngui sh and the light s usual ly as s ociat ed wi th an engi ne st all wi ll il lumi nat e. As ares ult t he dri ver will be requi red to perform a convent ional engi ne res tart.
Alt hough st all recovery i s a feat ure of t he St op/Start sys t em i t is pos si ble for it t o acti vat e i ndependent ly from t heStop/St art parameters . For exampl e:
If the St op/Start s ys t em has been deact ivated by the driver st all recovery wi ll s ti ll funct ion.Stal l recovery wil l act ivate at ambi ent temperat ures as l ow as (minus ) - 2°C, whereas the St op/Syst em operat ingt emperature threshold is above 4°C.Different t o t he operat ion of t he Stop/St art s yst em, s tal l recovery wil l st il l functi on when the vehicle is t owing;refer to the ‘Trail er Towi ng’ s ect ion.
• NOTE: As t he neces s ary cri teria will not have been sat is fi ed when t he vehi cl e i s at the beginning of a journey s t allrecovery wi ll not functi on. For exampl e, if t he vehi cl e s tal ls when l eavi ng the garage or driveway a convent ional engineres t art wi ll be required.

The t rail er towing sys tem inhi bi ts St op/St art as i t is pos s ible that trail er power requirements could interfere wit h t heoperati on of the bat tery monit ori ng s ys t em. In parti cul ar, a t rai ler batt ery could revers e t he feed current t o t he vehicleduri ng an engi ne cranking event , t hi s coul d pos si bly:

Climate Control System
• NOTE: The ‘ECON’ butt on has been renamed ‘A/C’ to prevent confus ion wi th the St op/St art s yst em ‘Eco’ s wit ch.
A number of changes have been made to the l ogi c and operati on of climat e control system, wit hi n a St op/St art cycle to:
maint ain occupant comfortprevent winds hi eld mis ti ngcons erve bat tery power.
This has been achi eved by the ATC (automat ic t emperat ure control) module monit oring and varyi ng, as necess ary variousclimate control funct ions wi thi n a St op/Start cycle.
In s ome circums t ances t he ATC has t he capabil it y to inhibit an engi ne s hut down or init iat e an engine rest art wit hi n aStop/St art cycle. Thi s i s achi eved by t he ATC module communi cat ing wit h t he CJB on the medi um s peed CAN. The variousoverri de functi ons the ATC has in a St op/St art cycl e are di s cus s ed bel ow:
Coolant temperat ure
The ATC module wil l i nhibit an engine shut down or i nit iat e an engine res t art wi thi n a St op/Start cycle if t he coolantt emperature fal ls below the calculat ed t hreshol d to s upport t he cabin t emperat ure s et by t he vehi cl e occupant s .
W i nds hiel d demis t ing
The variant of cli mate control fi tt ed t o the vehicl e influences t he s oft ware changes that have been made. For exampl e, thebase cl imat e-control s ys tem does not have a humi dit y s ens or, as us ed on a highline sys tem t o ini ti at e a winds hi elddemis t . Therefore, a calculat ion for demis ti ng the winds hi eld i s made us ing t he s ignals from t he rai n s ens or and ambientt emperature s ens or. Us i ng the probabi lit y t hat windshi eld mis ti ng wil l occur if i t is raining and t he ambi ent t emperat ure i scool , the ATC wil l presume a wi nds hiel d demis t is required and s tart the engine when i n a St op/St art cycl e.
Evaporat or temperat ure the main cause of windshi eld mis ti ng is al s o monit ored and t he high-line cl imat e cont rol s yst emwil l periodicall y cool t he evaporat or as neces s ary t o reduce mi s ti ng during a Stop/St art cycl e. The sys tem operates thewinds hield demis t s hut ter and i f the evaporator i s wet t he shut ter wi ll remai n clos ed for a few seconds after an engineres t art unti l the vapor is di ss ipat ed.
If the driver sel ect s eit her ‘programmed defros t ’ or t he ‘wi ndshi el d heater’ i t is as s umed t hat a qui ck demis t of thewinds hield is requi red. Therefore, t he ATC vi a the CJB will ei ther: i nhibit an engine shut down or i nit iat e an engine res t art .
Heater fan speed
Duri ng an engine s hutdown t he ATC monit ors cabin temperat ure and maint ai ns the fan speed at a l evel that wi ll cons erve,for as l ong as poss ibl e t he heat i n t he core of t he cabi n heat er. If the driver s elect s a hi gher fan s peed and the heatcannot be mai ntained i n t he heat er core, the engine will rest art .
Heated rear window and heated s eats
If the heated rear window or heated s eats are acti ve or act ivated during an engine shut down event t he power out put oft he relevant s ys t em wi ll be i nt errupted unt il the engi ne is rest art ed. The tell -t ale light i n t he relevant s wit ch wil lil lumi nat e t o i ndi cat e t he s ys t em i s act ive even t hough the s ys tem is recei vi ng no power. This feature is us ed t o conservebatt ery power.

Fuel fired heat er
The FFBH (fuel fired boost er heat er) and St op/Start s ys t em wi ll not operate si mult aneous ly, due to low ambientt emperatures bei ng a fact or in t he funct ion of both sys tems .
Hood Latch Ajar-Switch
W ARNING: To avoi d injury when performing repai r work on t he vehicle al ways di s abl e the Stop/St art s ys tem bypres s ing t he ‘ECO’ butt on, ens ure that ‘ECO STOP/START OFF’ is di s pl ayed in t he mes sage Cent er and the ECO tel l-taleli ght in t he s wit ch is ext inguis hed.
The hood lat ch ajar-s wit ch hardwired to the CJB, has two functi ons :
