Find the real cause. Fix it once.

Advanced Vehicle Diagnostics

A check engine light or a strange intermittent fault is a symptom, not an answer. Plenty of shops can read a code and start replacing parts until something works. We do the harder part: finding the actual root cause so the problem gets fixed the first time instead of guessed at three times.

With 18 years behind the scan tool, the oscilloscope, and factory wiring diagrams, we track down the no starts, stalls, warning lights, and electrical faults that get sublet to a specialist. If you have already paid for parts that did not fix it, this is where that stops.

What this covers

  • Check engine light and warning light diagnosis
  • Intermittent and hard to reproduce faults
  • No start, no crank, and stalling problems
  • Electrical faults and parasitic issues
  • Rough running and drivability complaints
  • Second opinion diagnostics after another shop got stuck

Signs you might need this

  • The light keeps coming back after a repair
  • The problem only happens sometimes
  • Another shop replaced parts and it is still broken
  • You were quoted a large job and want to know it is actually necessary

How we approach it

  1. 1

    Verify the complaint

    We confirm what the vehicle is actually doing, not just what a code says.

  2. 2

    Test, do not guess

    Codes and freeze frame data point the direction. Then we measure with a scope and meter against factory specifications and follow the circuit to the fault.

  3. 3

    Explain and quote

    You get a plain language explanation of what is wrong and a straight quote before any repair work begins.

Common Questions

Do you charge for diagnostics?

Yes. Diagnostic time is the skilled work that pinpoints the real problem and keeps you from paying for parts you do not need. We confirm how it works for your situation before we start.

My regular shop could not figure it out. Can you help?

That is a large part of what we do. Bring us the problem the parts cannon did not solve. We diagnose complex electrical and intermittent faults that general shops are not equipped to chase.

What kinds of vehicles do you work on?

All makes. Our diagnostic and programming equipment covers domestic, European, and Asian vehicles.

Have a problem no one else can solve?

Tell us what your vehicle is doing and we will tell you how we can help. Call, or start a chat and we will get right back to you.
