We charge $90 an hour, takes about 30mins max to get the codes, MTA approved workshop. Why spend more going to Toyota? Going from what my mates at dealerships go by, I'd rather take my car to a private place! Nothing wrong with them, but nothing worth the extra money.
And yeah, we have one of the hand held ones. Plug it into the ECU, it gives you the code, and then you can go from there. Easy as!
