By Kencoul

I've been driving different cars for many years, and, to be honest, I used to check only petrol, oil and tires before a ride. Until the day I struggled within a desert. The engine of the car I rented got broken and there were no chances to repair it by myself. A few days later I had a conversation with my old pal, who is an owner of Car Alarm Service Company.

He told me about car reader tool or so-called OBD II (On-Board Diagnostic Level Two). This thing can define many problems and damages and prevent many uncomfortable situations.
