With the evolution of today’s technology and engineering, all vehicles come with an engine control unit (ECU) that oversees various components in the vehicle. The sensors within the ECU can detect issues like worn brake discs, low fluid levels, engine overheating, or loss of power.
Diagnostic tools can also check a car’s computer system for manufacturer notifications and stored information about the car’s history, giving technicians a complete breakdown in order to perform the best repair possible.
