Below is a YouTube Video from Australian Automotive Engineer John Cadogan.
He gets stuck right into Austalian Dealerships and Australain Gov for allowing the lock up of technical information for servicing vehicles trying to protect the massive revenue dealerships make from servicing. In the USA this is illegal and goes against their consumer Law and also their Fair Trading ---- funny I like that last one "Fair Trading" don't we have this here
Anyway enjoy John going to town - but I must warn you there is a strong language warning ---- because I know all you Hilux owners "butter won't melt in your mouth"
