The first indication that you have a potential problem with your ECU is often a warning light on your dashboard. And when these various symbols light up the best approach is usually to pull over and consult the manual to see what the light means. These symbols are difficult to decipher but to actually get to the root of the problem you really need to run a full diagnostics check which should pinpoint the issue exactly.

What is an ECU

The electronic control unit (ECU) used in today’s cars and trucks are used to control the engine and other components’ functions. The vehicle’s engine computer ECU is used to operate the engine by using input sensors and output components to control all engine functions. When running a full diagnostics check we plug directly into your vehicles ECU and take a reading of the data stored there. With this data, we can determine where any potential faults may be occurring across your vehicle.
