OVERVIEW
The 3.2L Si 6 engi ne igni ti on sys t em has a s i ngl e iridi um t ipped s park plug per cylinder, wit h each spark plug powered by anon-plug ignit ion coil . The ignit ion coil s are di rectl y dri ven by the ECM.
Power for the ignit ion coil s is suppli ed from t he mai n rel ay and a fus e in t he BJB. A capacit or is connected in paral lel wit ht he power s upplies t o t he i gni ti on coi ls t o s uppres s RFI (radi o frequency i nt erference).
Each ignit ion coil cont ains a power s t age to swi tch t he current i n t he pri mary ci rcuit . The ECM cont rol s the swi tching wit h as ignal to t he power s tage. The ECM monit ors operat ion of t he igni ti on coi ls us ing a feedback s i gnal from each of t he powers tages . If a fault i s det ected t he ECM s t ores an appropri ate fault code.
