Advanced Automotive Diagnostics in Chicago

A warning light or an unexpected vehicle problem doesn’t always tell you which part needs attention. Tachyon Auto Service provides advanced automotive diagnostics to help identify the cause of engine, transmission, and electrical concerns.


Based in Chicago, we offer mobile service across Chicagoland and Northwest Indiana. Contact us to discuss your vehicle, symptoms, and location.

More Than Reading a Trouble Code


A trouble code is a starting point—not a complete diagnosis. Similar symptoms can have different causes, and replacing parts based on a code alone may not resolve the problem.

Diagnostic testing helps narrow down the issue and determine what needs further attention before repair or programming decisions are made.

Tell Us What Your Vehicle Is Doing


When requesting an appointment, include:


  • Your vehicle’s year, make, and model.
  • Any warning lights or diagnostic codes.
  • Whether the vehicle starts and drives.
  • When the problem occurs.
  • Any recent repairs or replaced components.
  • Your location and whether you need mobile service.

Frequently Asked Questions

Not necessarily. A warning light can relate to many different systems. Diagnosis helps determine whether the concern involves a component, wiring, software, or another issue.

We offer mobile service. Contact us with your location and vehicle concern to confirm whether your appointment can be handled on-site.
