Computer Diagnostics

All modern vehicles have a computer or ECM (Electronic Control Module) that controls the operation of the engine’s fuel injection system, ignition timing, and the idle speed. Sophisticated computerized systems within your car constantly monitor its engine and electrical performance. When a malfunction is detected, the warning light will illuminate on the dash to alert you to a problem. In some cases, the light may go off by itself and then come back on later. In other cases, the Check Engine light may come on and remain on.

Not every engine problem gives you obvious signals like hard starting, rough running, or stalling. The best thing about the Check Engine light is that it is often an indicator of little problems before they become big and expensive. That’s why it is very important not to ignore this light. The simplest way to handle a Check Engine light is to bring your vehicle to UAG. Our technicians use special diagnostic equipment to read the computer codes that have been logged by the ECM. By combining these codes with their knowledge and experience, our technicians are able to find and correct the problem so your vehicle is back to running its best.
