Vehicles no longer have just one or two computers in them, but nowadays many have upwards of 20 modules, or even more.
Each module requires proper voltage and control software to make sure they all work in conjunction with each other. Warning lights and messages should be checked out as soon as possible, especially if they are flashing.
To deal with these modules, the work required is often much more than reading codes. From a small check engine light to major system issues, we are equipped with the manufacturer scanner software required to interface, diagnose, and re-initialize modules to get you back on the road.
