@Gaz - yeah you won't be able to view the
CMP signal from a scan tool because it's way too fast - there are 35 teeth on the crank wheel. Have a look at the graph about half way down the page on the following link to see what the
CMP signal would look like - you'd need a proper oscilloscope to view it.

AU uses EDIS ignition system which runs purely off the crank position sensor, the cam sensor is just to control the sequential injection.
