Ok i have started hearing and reading about OBDII port which became compulsory in 96+ cars. My question is does my 1990 Celica "GTS" (actually its an Aus SX) have this port or something similar? I would love to be able to read realtime data off my ECU and be able to display the info on my laptop/PDA.
im not planning on spending alot of money on a toyota program, iam a programmer myself and have a bit of experience in electronics. I cant find much information on this so any information would be very much appreciated
It's OBD I. There are adaptors made for every single manufacturer DLC on pre-OBD II vehicles. On Toyota's, the DLC is a little gray box with the word Diagnosis on top of it. And FYI, it's not live data. It actually takes a couple of seconds. The older the vehicle, the slower the computer.
I just have some minimal wiring diagrams that are in th Haynes manual, its the US manual but they apply to the Aussie cars too. Let me know if theres something in particular you need and i'll scan it at work for you.
