Can you tell me how to check the code for a chech engine light for a 1991 toyota supra. All I have been able to findout is you have to put a jumper in a plug and count the check engine light flashes. Is this correct - where is the plug located and what are the codes - what do each type mean? Hope you can help.
Thanks
Jeff
