Toyota Obd1 Serial Interface Standards
Some Toyota ODB-1 ECUs have a serial output allowing an appropriate scan tool to read and display live engine operating parameters, similar to what a standard OBD2. OBD-1 Serial Interface - Toyota Wiki. Similar to what a standard OBD2. OBD II Connector Pinout. You can see more picture of Obd2 pinout toyota in our photo.
Thanks guys for the replies. What I have learned is that lots of data, such as the ABS data, doesn't show up for most generic OBD readers. You need something better.
So I started searching for that something better, and came across these guys. They have several options, basically if you go with them it will cost you about $360 to be able to read the low level ABS data. I have no idea if this brand is any good or not, or if there are cheaper options, I'm just taking what they emailed me at face value: Here is our email exchange: My question: I need to troubleshoot both an ABS issue and a fuel gauge / fuel tank issue for a 2008 Prius. Can you please tell me exactly what I need to buy from you to be able to see all data on the related systems? Their reply: Thank you for your interest in EASE Diagnostics. We do offer Personal Level Software for Toyota however, you would need an EASE Pro Level Interface or Toyota Mongoose Interface to support the Software.
You would need Level 1+2 software for $159.00 + a supported Device. The EASE Po Level Interface and OBDII cable is an additional $200.00 if you do not have the Toyota Mongoose already. Click to expand.Only because the software isn't capable enough?
Or because the data you need doesn't pass through the ODBII interface at all? - Am I correct to think that ODBII is just a series of pins, like a serial interface - i.e. The adapter doesn't matter much? An adapter would only translate whatever data the OSBII interface supplies into data that a BT device could read? Does the adapter matter at all?
Then then next question is, does ODBII supply the needed (ABS) info at all? If ODBII does supply the info - then it's just a question of finding the right software - if it's available at all separately from the adapter. If it does not - then like you said, you have to find something else. Click to expand.It can be a bit of both. There are a bunch of pins on the diagnostic connector there, with different ones used for some different physical layer communication standards (K-line, CAN, etc.), and some not even really used for serial communication at all, but just for signaling certain ECUs in the car by pulsing them to ground or other specified voltages.
It's essentially a 'standard' creating by combining the several different approaches car manufacturers were using at the time. Not all OBD-II hardware dongles will be electrically able to support all the signaling methods, baud rates, and so on, used in the car. Then, if you get one that does, there is still the software issue. OBD-II standardizes certain pieces of data (mostly to do with engine control and emissions) that have to have the same addresses and data formats in all cars, and all standard OBD-II reading software knows how to retrieve those. Everything else is vehicle-specific and often can be read if the software you are using has a way for you to enter custom PIDs and conversions, and if you are able to figure out what those are. There are extensive threads here on PriusChat where people have reverse-engineered a lot of the PID addresses and conversions for a lot of the data in the car.

Again assuming you have a dongle that supports all the right physical layers. There are a couple basic styles of dongle floating around: one that's based on the command set of the ELM Electronics ELM327 chip, which can usually talk to some but not all of the car's stuff, and another based on an SAE standard called J2534.
The official Techstream laptop software from Toyota requires a J2534 dongle that can do all the necessary tricks. And yes, you can retrieve the ABS info with a J2534 dongle. However, if you are having an ABS issue, you might not want to wait for getting your perfect code reading setup; the ABS computer is built so you can also get those codes by jumpering two pins at the diagnostic connector and counting blinks of the lights on the dash. You could do that right away. They are your brakes, after all.

Jamaica's mellow reputation and Rasta vibe contributes to an international reputation of an island nation that moves at a leisurely pace. And the term 'leisurely' certainly applies to the rate of sales of hybrids there.

And we thought Mitsubishi i sales in the US have been slow. The country's Toyota dealership is still in the process of explaining hybrid technology to many of its prospective. With a dozen years atop the nation's best-selling car charts, you might think that there wouldn't be a lot of incentive for Toyota to rework its Camry, particularly so early in the life of the current model. But despite its unassailable sales totals, the midsize sedan has come in for substantial criticism for its milquetoast dynamics, piecemeal interiors and bland design. As part of CEO Akio. Today, October 21, 2015, is the day movie geeks have been waiting for.
Some might call it 'heavy.' It's when Dr. Emmett Brown, Marty McFly, and Jennifer Parker will arrive from the year 1985, as told by the events of Back To The Future Part II. It's more than just film buffs that have been waiting for this date, though. Toyota, which provided the customized pickup that McFly's character lusted.
