this will take you to a list of the fault codes and what they mean for the Nova GSi.

To put the car into "dianogic" mode you need to effectively "short" the two pins where Vauxhall would insert Tech 1.

This will then flash.

The way to read it is this.

3 quick flashes followed by 4 shorter flashes indicated fault code 34.

Then just read the list and see what it is.

another example

6 quick flashes followed by 4 short flashes indicates fault code 64.

One you turn the ignition back off the ECU will continue to show the fault until cleared by tech 1, but at least you will know what it is.

I hope this helps.

dont forget it does a start/finish sequenece, i think its 3 sets of 3 flashes, and then it will read the code out.

pot on here what it is and we will help pinpoint the problem. also what car, mods etc (its it suppose to have a cat and uv removed it, lambda sensor etc)
