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 .

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 :

Theengi ne can be res t art ed usi ng t he ignit ion but ton. Stal l recovery wil l not funct ion i n t hi s condi ti on; refer t o t he StallRecovery secti on.
Aft er the hood i s clos ed reacti vat ion of t he Stop/Start sys tem is achieved by manuall y s tarti ng the engine.
System Fault
The Stop/St art s ys tem is aut omati cal ly acti vat ed each ti me an ignit ion cycl e occurs; t he dri ver will be i nformed t he sys t emis operat ing by the t ell -t ale l ight in the Eco s wi tch i lluminati ng. If the tell -t ale light does not il luminat e t hi s wi ll indicat et hat t here i s eit her a s ys t em faul t or the sys tem is not avail abl e. Onl y when t he dri ver at tempt s t o act ivat e t he sys t em bypres s ing t he ‘Eco’ but ton will t hey be informed of a fault by ‘ECO STOP/START FAULT’ being di spl ayed i n t he mes sageCenter.
Owi ng to the St op/Start s ys t em’s complexit y due t o many ot her vehicle modul es and communicat ion net works i nvol ved i nit s funct ion. It i s recommended t hat al l ot her sys tem faul ts be init ial ly diagnos ed and eliminated when inves t igati ngStop/St art fault s as t hes e could affect the operat ion of t he St op/Start sys tem.

OVERVIEW
A gl ow plug i s i ns t alled in t he inl et si de of each cyli nder, to heat t he combus t ion chambers before and duri ng cranki ng.This ai ds col d s tarti ng, reduces emis s ions and engine nois e when idli ng from a col d engine.
A wi ri ng harnes s on each bank of glow plugs is connect ed t o a s eparat e rel ay and fusible li nk in t he BJB (bat t ery junct ionbox) . Each glow plug i s grounded through i ts fi xi ng in the cyli nder head. Operati on of the gl ow plug relays is cont roll ed byt he ECM , which al so cont rols the i ll uminati on of the gl ow plug indicator in the instrument cl us t er.
Each gl ow pl ug is a tubular heati ng element which cont ains a spi ral fi lament encas ed i n magnesi um oxide powder. At t het ip of t he tubular heati ng element is the heater coil . Behi nd the heat er coil , and connect ed i n s eries , is a cont rol coil . Thecont rol coil regulat es the current to the heat er coil t o s afeguard agains t overheat ing.
OPERATION
There are t hree phases of glow plug heati ng: Pre heati ng, crank heat ing and pos t heat ing. The ECM (engi ne cont rolmodule) determines t he heat ing ti mes from the ECT (engi ne cool ant temperat ure) . The lower t he ECT (engi ne coolantt emperature) , t he l onger t he heat ing t imes .
W hen t he i gni ti on s wit ch is s wi tched to mode II, t he ECM (engi ne cont rol module) calculates any requi red heat ing t imesand, i f heat ing is requi red, energizes the gl ow pl ug relays i n t he BJB (bat tery juncti on box) . W hen pre heati ng is required,t he ECM (engi ne cont rol module) als o s ends a mes s age to the i nst rument clus t er, on the high s peed CAN (cont roll er areanetwork) bus , to request i ll uminati on of the gl ow pl ug indicator. The gl ow pl ug indicator remains il lumi nat ed for thedurat ion of t he pre heati ng phase, or unti l the i gni ti on s wit ch is t urned t o t he crank pos it ion, whichever occurs fi rs t. Ifrequired, the ECM (engine control modul e) keeps t he glow pl ug rel ays energi zed during cranking and for the durati on of anypost heat ing phase.
The ECM (engi ne cont rol module) moni tors the drive circui t of the gl ow plug relays for pl aus i bi li ty of operat ion, cont inuit y,and s hort and open ci rcuit s . If a fault i s detected, the ECM (engine cont rol module) s tores a rel ated faul t code andpermanentl y il lumi nat es t he glow pl ug indicator whi le t he i gni ti on s wit ch is i n mode II.
