If a vehicle’s check engine light is on, computer diagnostics will generally reveal the source of the problem. By hooking the car up to the computer diagnostics machine, Mastercare Automotive technicians can determine whether the problem stems from electrical issues, a bad sensor, or a faulty mechanism in the vehicle. If the check engine light is not on however, Mastercare Automotive technicians may have to rely on methods outside of computer diagnostics to locate and remedy the source of the problem. For this reason it is wise for drivers to leave their repairs to Mastercare Automotive technicians that can employ a range of techniques when servicing a vehicle.
