Check Engine Light

Check Engine Light

We have all been there before: That moment when your Check Engine light comes on and panic consumes you. What does that light mean? Where should you have it serviced? Today’s vehicles are primarily computer-controlled and utilize sophisticated technology to operate properly. The use of this technology plays a significant part in the diagnosis of your vehicle’s performance. When your vehicle is illuminating the “Check Engine” light or not running properly, oftentimes computer diagnostics are needed to determine what part is malfunctioning.

What Does It Mean?

When a Check Engine light is illuminated, this means the onboard computer system in your vehicle has detected a problem or service need with one or more of the many different systems it monitors and controls, such as your engine or transmission. When this occurs, Milex Complete Auto Care recommends a Computer Diagnostics service to provide you with an accurate assessment of your vehicle’s condition. Our Computer Diagnostics service utilizes state-of-the-art diagnostics equipment, which is connected to your vehicle to view any computer trouble codes. These advanced diagnostic scanners are much more sophisticated than those used at the parts store. DTC's (Diagnostic Trouble Code) are categorized by engine, transmission and body control modules. Not all DTC's will cause the Check Engine light to illuminate and not all DTC's will be seen by the parts store scanners. Its best to know all of the DTC's when diagnosing the issue with your vehicle. 

Why Milex?

Our trained technicians utilize the same procedures the dealerships perform by retrieving this information directly from the vehicle’s data stream to accurately pinpoint your system’s failure or service needs. Once the data is retrieved from the trouble code, our technicians can provide a service or repair recommendation to eliminate the Check Engine light, restoring your vehicle to its initial road-ready condition.

At Milex Complete Auto Care, we take pride in fixing only what needs to fixed, nothing more. Our Check Engine light services are no different.

To have your Check Engine light diagnosed, find your nearest Milex Complete Auto Care to consult a professional.

FAQs About Check Engine Light

What does a flashing light mean vs. a steady light?

A flashing light indicates a critical problem that is currently happening and requires you to pull over and shut off the vehicle. Not pulling over you run the risk of damaging your vehicle.  A steady check engine light can be diagnosed at your first convenient opportunity. But don't put it off for too long as the condition may affect other components.

How does a technician check the light?

A technician connects a diagnostic scan tool to your car’s on-board diagnostic system to determine the problem. Further diagnostics may be required to pinpoint the exact cause of the problem.
