How We Perform Computer Diagnostics at Ares Fleet Service

Beneath the hood, your car or truck has dozens of sensors and control modules working together to manage everything from fuel injection to emissions control. When something goes wrong, those systems communicate with the onboard computer (ECU).

At our shop, we use specialized tools to read those error codes, analyze the information, and determine what systems may be malfunctioning. While a check engine light may seem vague, a proper diagnostic scan can reveal whether the issue is minor or major.

Your vehicle is running rough, stalling, or losing power

As a family-owned and operated shop, we’re deeply committed to serving our neighbors with honesty, transparency, and fair pricing. We use the same high-tech scan tools as dealerships, giving us access to precise and detailed information across many makes and models. Diagnostics help us fix your vehicle right the first time, avoiding wasted time and money.
