Today, during the 70s and early 1980s manufacturers started using electronic means to control engine functions and diagnose engine problems. This was primarily to meet EPA and mission standards through the years onboard diagnostic systems have become more sophisticated obd2. A new standard introduced in the mid 90s provides almost complete engine control and also monitors parts of the chassis body and accessory devices, as well as the diagnostic control network of the car. Obd simulator is a device which simulates obd2 data on ken bus it having the minimal hardware required to generate data on ken bus hardware. Setup is shown in the picture. I used Arduino and CANbus shield to make obd2 simulator other side. Esp 32n can driver IC, MCP to 5 v 1.is obd ii data parse. I developed GUI based software on Windows to change obd data dynamical from the computer. You can find more information about obd on wikipedia here’s, the request and response data format for obd2 obd2 data reader needs to create a request for PID in this form. At ECU will, then send a response to a particular request and the format is shown here. You have to parse frame like shown here. This is PID here you find the information about PID let’s, see how we create obd to request. The request consists of 8 bytes of data. The first byte for a number of additional data is 2. The second byte for mode is 1. The third byte for PID is PID.

We are requesting rest of the bytes are either 0 or 55 X. Now respose for request is created like this and send by arduino you you here, we print ESP 32 logs on the console. First, he SP 32 scanned the all obd2 PID, which is supported and stores it for requesting one by one. You, after scan completed, we found 11 supped PID. Here is current data from arduino. You can see the request coming on arduino serial terminal. You now close Arduino terminal, install arduino, obd, simulator software, you you, you select comport and baud rate 9600 open connection. You can now change obd2 data from software and it will reflect at obd scanner.
