Year of Manufacture *: 2007
( Optional ) Engine Code or CC: 1.1
This code intermittently logs. 'Scope testing reveals that when running normally, both primary and secondary voltage traces are normal. Likewise coil primary current. When the engine misfires coil primary for cyl 2-3 doesn't switch on. Coils 12v supply good at all times.
Wiring continuity appears good, wiggle test etc.I think the coil driver in the ECU is intermittently failing.
My main question, does this ECU need coding to the car? IAW 4AF 61601.123.02 (It's not the engine mounted one like the later Punto)
