Direct Ignition System (Dis)
Direct ignition system consists of 2 coil packs, ignition module, crankshaft position sensor and PCM. Coil packs consists of 6 independently mounted ignition coils (at plug). Ignition control module (ICM) receives ignition control signals from PCM which in turn triggers corresponding ignition coils. PCM controls spark timing and ignition control during crank and run, there is no by-pass mode. ICM is not repairable.
Crankshaft position sensor magnetic pick-up provides a signal to PCM to identify correct firing sequence and crank signals to trigger each coil at proper time. PCM controls timing and fuel injector pulse width using crankshaft position, engine RPM, engine temperature, MAP sensor and VSS input signals.
