Toyota obd1 serial interface for arduino

Unfortunately for this to work you MUST have a Shield from SeeedStudio Called the CAN-BUS Shield. OBD2 Diagnostics software (Just to Test if it works) any OBD2 software should work, the software you got with the ELM327 scanner should do just fine. But at the end i could connect a FreeObd Scanner program which you normally get with your ELM327 Scanner.ĮLM327 (USB,Bluetooth,Wifi) It doesnt matter which flavour you have. So unfortunatly and fortunatly for you :-) I had to figure out how i'm going to build one my self, which forced me to now focus on a project i had to take on in order to complete my initial project, Took me some time to figure out how to send PIDs in standard OBD2 format. I came across one or two websites that's making use of Arduino to build an OBD2 Simulator but they dont give you the code you have to buy the ready made product from them, I.E the FreeMatics for something like a whopping $169, Wheres the love for Open source in that ? pffft! I dont see $169 I see about 8 Arduinos i can buy with it. Ive searched high and low and couldn't find any Arduino OBD2 simulators that i can build my self.

I needed to find a way to test my prototype in the comfort of my home. Ive been building an Arduino OBD2 Scanner to interface with my Jeep's OBD2 port, but it became a beeeeeg! schlep to upload code to my Arduino Nano + 16x2 LCD + ELM327 Scanner device, then haul the whole prototype to the Jeep in the gurage the whole time and then only to find there was something small i forgot to change.
