FAQs

  • Your visit includes a system scan, relevant testing, visual inspection, and real-time explanation of findings. We bring the shop to you—so we can test components under actual operating conditions. We’ll provide a summary of what we found, what caused it, and your repair options. Most mobile diagnostics last 45-90 minutes depending on the issue.

  • No. If we recommend a fix and it doesn’t solve the problem, we refund your diagnostic fee. We don’t charge for wrong guesses.

  • Intermittent concerns can be very difficult to diagnose and sometimes can require multiple hours of diagnosis to come to a concise conclusion. Using a wide array of service data tools our technicians are equipped with as much information as can be expected by an independent repair facility to correctly, diagnose concerns quickly and effectively, even when they don't show their face consistently.

  • Absolutely. We don’t just read the code—we dig into the system, sensor signals, and conditions that triggered it.

  • Not at all. We give you options, not pressure. Our job is to figure out what’s wrong and explain it clearly. Whether you fix it with us, another shop, or on your own—we want you driving away with real answers.

Our Diagnostic Philosophy

At Caleb’s Car Care, we don’t just scan for codes—we solve problems. Modern vehicles can throw multiple codes for one issue or a single code for unrelated problems. That’s why we rely on training, real-world testing, and factory-grade tools instead of shortcuts.

  • Our goal is simple:

  • Find the real cause of your concern

  • Explain it in plain English

  • Help you decide your next move with confidence

  • We’re here to out-diagnose the dealership—without the dealership games.

Common Issues We Diagnose

  • Car won’t start or hard starting

  • Repeated blown fuses or battery drain

  • Check engine light or warning indicators

  • Rough idle, poor fuel economy, or stalling

  • Strange smells, noises, or vibrations

  • Faulty sensor readings or inaccurate dash info

If your concern points to an electrical fault, we can go deeper with our Electrical Diagnostics service.

Tools and Methods We Use

We combine OEM-level tools with proven testing methods to deliver accurate results every time.

  • Professional-grade scan tools with OEM access when needed

  • Multimeters, test lights, and pressure gauges

  • Live data monitoring and freeze-frame analysis

  • Factory service manuals and technical bulletins

  • Visual inspection and functional testing

  • VIN-specific wiring diagrams and flowcharts

Once we identify the problem, we explain what’s wrong and your options. If it can be fixed on-site, we’ll handle it immediately. If a part needs to be ordered, we’ll give you an exact quote—no pressure, no surprises.

Why You Shouldn’t Wait

Ignoring a car problem usually makes it worse—and more expensive. A small short can turn into melted wiring. A misfire can destroy a catalytic converter. The sooner you get a diagnosis, the more likely it is to prevent bigger repairs down the road.
