2JZGTE VVTi OBD Scanning and Information

While I had a stock engine and ECU I really strugged to find much information or tools to scan the 2JZGTE VVTi engine in my supra, standard OBDII tools did not seem to work. Some guys had tried and failed or got mixed results. I did find a guy in the UK that found out how, but it seemed one of his friends was a Toyota Mechanic and had access to an expensive scanner tool which wasn’t an option for me.

I’ve hopefully now found some basic information for the Toyota Supra 2JZGTE VVTi ECU;

-Is not OBDII compliant, it uses an JOBD compliant protocol as it’s a Japanese ECU –
-Uses a OBDII connector but requires a scan tool with correct software to read the correct protocol which is ISO 14230

It now seems like there is a cheap solution for reading the protocol; Thanks to Muzzytt on supraforums.com.au and Konrad on mkivsupra.net for sharing this information around on the forums.
