Fiat Punto 1.2 ECU from year 2000 onwards

Learning the phonic wheel,

The engine must be up to temperature (75 degrees plus), and the engine needs to be rev rapidly above 5000 revs and allowed to rev down on its own. The easy way to do this is just to stab at the throttle pedal and release it, the engine revs need to come down on their own so as soon as shes reached 5000 revs remove your foot completely from the throttle. This needs to be done three times in a row and provided you have done this correctly the light will stop flashing, switch the engine off and leave the ignition off for the power latch period (60 seconds) before restarting.

Fault symptoms include:

Fault code PO351 / PO352 coil failure
