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.
