Last week my old Volvo suddenly stopped in the middle of a street in the city. Not a pleasant situation. Even worse! It showed an error message, and I could no longer start the engine anymore. I had to push it to the sidewalk and call my brother, a trained mechanic. The problem was smaller than I thought, and it can happen to you, too. Maybe you want to accompany me on my trip to prevent such things from happening again?

Thanks. Practical use for a practicle problem and reminds me of an automotive need I have. I frequently forget to turn off the blinker and feel like an idiot what I find out. Also, road noise overwhelms my poor hearing. Sooo, I have an idea to use a Atmega chip to increasingly turn up the volume of a secondary alarm. With your learning maybe I could tap into the CAN bus to retrieve a blinker message to triger the volume increases. Ha - another project for the future for me!

I used to get a check engine light in my car due to oxygen sensors going bad. Luckily they didn't disable my car, but it was annoying. I got the Sparkfun CAN BUS shield and cabling and through some research was able to figure out what code it was for the oxygen sensors and programmed the Arduino to turn the trouble code off each time it turned on. One of my favorite projects.

Hi Jeff, That is exactly what I want to do. Do you still have the code? It maybe would point me in the right direction.

Hi Craig, I do not know if all messages are transferred to the OBD connector. It seems that modern cars not only have one bus but a whole network of buses with "routers". But maybe you are lucky and you detect the signal. The driving speed to increase the volume can easily be read.
