Advanced Diagnostics & Electrical Repair

Is your Check Engine Light on? We don’t just pull codes - we solve the problem.

Modern Cars Are Rolling Computers

Gone are the days when you could fix everything with a wrench. Today’s vehicles - like the modern Jeeps and EVs we see daily - rely on complex networks of sensors, computers and miles of wiring. When a warning light pops up on your dashboard, it’s your car’s way of asking for help.

At Discount Muffler, Brakes & A/C, we speak your car’s language. We use factory-level diagnostic equipment to communicate with your vehicle’s onboard computers, isolating the issue quickly so you don’t waste money throwing parts at a problem.

Our Diagnostic & Electrical Services Include:

  • Check Engine Light Diagnostics: A code reader tells you what happened, but not why. We trace the code to the root cause—whether it’s a vacuum leak, a bad sensor, or a wiring fault.

  • Electrical "Gremlins": flickering lights, power windows that won't roll up, or door locks that are stuck? We are experts at tracing shorts and open circuits in the wiring harness.

  • Starting & Charging Systems: We test your battery, alternator, and starter to ensure you aren't left stranded in a parking lot.

  • Sensor & Module Programming: From ABS modules to Body Control Modules, we handle the complex electronics that keep your car running safely.

  • Battery Replacement: We stock high-quality batteries built to survive the extreme Las Vegas heat.

Why “Free Scans” Aren’t Enough

Many auto parts stores offer a "free scan," but that often leads to expensive guessing games. A code for an "Oxygen Sensor" might actually be caused by a fuel injector or an exhaust leak. If you replace the sensor, the light comes right back on. We test the system to confirm the failure before we recommend a repair.

  • Advanced Equipment: We invest in the same scanners and software the dealerships use.

  • Hybrid & EV Ready: We understand high-voltage systems and modern vehicle architecture.

  • Honest Answers: If it’s just a loose gas cap (and it happens more than you think!), we’ll tell you.
