I would think most of the garages Lakeside have a simple OBD2 scan tool. You can pick them up for less than $50 US at Autozone.. They will read any existing faults or previous ones stored in the computer.. They may even have the more advanced version. For around $100/120 US you can pick up something an Inova OBD2 Digital scan tool that will give you real time data while you drive, which comes in very useful if you have an intermittent problem like I did...
