FAQs
Q: What’s included in a diagnostic visit?
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.
Q: Do I have to pay again if the first fix doesn’t work?
A: 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.
Q: What if my issue only happens sometimes?
A: 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.
Q: Can you diagnose a check engine light?
A: Absolutely. We don’t just read the code—we dig into the system, sensor signals, and conditions that triggered it.
Q: Will you pressure me to do repairs right away?
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 cars can throw five codes for one issue, or one code for five unrelated causes. That’s why we rely on training, not shortcuts. We use factory-grade tools, test live data while driving, and always confirm the root cause before we recommend parts.
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 include:
• 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
Tools and methods we use:
• Professional-grade scan tools (OEM-level 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 hands-on functional testing
• VIN-specific wiring diagrams and flowcharts
Once we find the issue, we explain exactly what’s wrong and what your repair options are. If the problem can be fixed on-site, we’ll handle it right away. If it’s something bigger—like a part we need to order—we’ll give you an exact repair quote with no pressure.
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. Don’t guess or wait it out.
