test is as shown in the first page of the thread, jumper the point with a paper clip, turn ignition on but don't start the car, count the flashes as described earlier.
Just Commodores - For All Your Holden Commodore Needs for a listing of vn fault codes

and i know it's a late reply but ozzykev, in the bottom pic to the left where the main loom is going to the engine bay through the carpet, looks like the aldl connector is looping back towards the firewall under the carpet/underlay, pull the smaller bunch of wires back
