Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Direct Ignition System (Dis): 1.6L
Ignition system is a 2-coil ignition system. There is no distributor. The Engine Control Unit (ECU) directly activates the power transistor to fire the coils and for timing control.
This system has 2 power transistors and 2 coils. Power transistor "A" controls primary current of ignition coil "A" to fire spark plugs on No. 1 and No. 4 cylinders. Transistor "B" controls primary current of ignition coil "B" to fire spark plugs on No. 2 and No. 3 cylinders. Although each coil fires 2 plugs, ignition takes place in only one since the other cylinder is on its exhaust stroke.
