#421 Home Made OBD2 Engine Alarm Resetter device using an Arduino?

January 11, 2025 Andreas Spiess

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?
