Don't Ignore That Check Engine Light—Here's What You Need to Know
May 6, 2025
At Jim Brangham Auto Repair in Cathedral City, CA, we Understand how tempting it is to ignore a check engine light—especially if your car seems to be running fine. But that little light on your dashboard is a warning. It means something isn’t right, and waiting could lead to much bigger (and more expensive) problems.

What the Check Engine Light Really Means
When your check engine light turns on, your vehicle’s onboard computer has detected something abnormal in your engine, emissions, or other critical systems. Sometimes it’s something simple like a loose gas cap. Other times, it can point to serious issues like a misfire or sensor failure.
If the light is solid, your car is telling you it needs to be looked at soon. But if the light is blinking, that means there’s a more severe issue. If this happens, pull over safely, turn the engine off, and call us right away.
How We Test the Codes
When you bring your car in, we use high-end diagnostic scanners—not just simple code readers. These tools are very advanced (and very expensive) and allow us to go far beyond just pulling a code. Our team uses these tools to read live data, run system tests, and analyze exactly what’s going on under the hood.
Each trouble code is a starting point, but one code could point to several different possible problems. That’s why our testing and analysis process is so important—we take the time to do it right and find the true cause before making any repairs.
Why There’s a Diagnostic Fee
We do charge a diagnostic fee, which covers the time our experienced technicians spend analyzing your vehicle with specialized equipment. These scanners cost thousands of dollars and require ongoing updates and training to use correctly. The fee ensures your car gets an accurate diagnosis—saving you money in the long run by fixing the issue the right way the first time.
Don’t Wait—Get It Checked Out
A check engine light doesn’t just go away—it will get worse and leads to more damage. Taking care of it now can prevent serious repairs later.

At Jim Brangham Auto Repair, we want every mile of your holiday travel to be safe and smooth. Here are the key items that should be inspected before any long road trip. Engine Oil and Fluids Fresh, clean fluids help your vehicle run at its best. Before traveling, your engine oil, coolant, transmission fluid, brake fluid, and power steering fluid should be checked to make sure they are at the right level and in good condition. Low or old fluids can create unnecessary strain on your vehicle, especially during long drives. Battery Health Cold weather can weaken a car battery , and the extra electrical use during holiday travel doesn’t help. A battery test can confirm whether it still has enough power or needs to be replaced before your trip. Brakes Safe braking is essential when you’re driving in heavy traffic or winter weather. A brake inspection checks the pads, rotors, and brake system to make sure everything is working properly. Tires Your tires affect traction, handling, and fuel efficiency. Before hitting the road, your tire tread, air pressure, and overall condition should be checked. Don’t forget to inspect your spare tire as well—just in case. Belts and Hoses Belts and hoses keep your engine running smoothly and help prevent overheating. If any are cracked, loose, or worn, they should be replaced before you travel. Lights and Wipers Visibility is especially important during holiday travel when roads are busy and weather can change quickly. Headlights, brake lights, turn signals, and wipers should all be checked to make sure they’re working the way they should. Heating and A/C System Whether you're driving through winter weather or across changing climates, your heating and cooling system should be tested to ensure comfort and clear windows. Air Filters Clean air filters help your vehicle breathe better and improve efficiency. If your engine or cabin air filter is dirty, replacing it can make a noticeable difference. Suspension and Steering Long drives make every bump more noticeable. A suspension and steering check helps ensure a smoother ride and better control on the highway. A holiday road trip should be filled with good memories—not car trouble. If you want to make sure your vehicle is ready, Jim Brangham Auto Repair is here to help. Call (760)321-7040 or click the "Book Service" button schedule a check-up before you hit the road, and travel with confidence this holiday season.

At Jim Brangham Auto Repair, we perform this type of smog testing to make sure older vehicles meet California’s emissions standards. Plus, it keeps your vehicle running clean and reliable. What Is a Dyno Smog Test? A dyno smog test checks how much pollution your car gives off while it’s actually running under real driving conditions. Your vehicle’s drive wheels are placed on a machine called a dynamometer, which lets your car “drive” in place. While your car runs through different speeds and loads, the system measures the exhaust gases coming out of the tailpipe. This process is part of the BAR-97 smog testing system. This is required by the California Bureau of Automotive Repair (BAR) for most vehicles built before the 2000 model year. Why Newer Cars Don’t Need It Cars built after 2000 have advanced onboard computers (OBD-II systems) that monitor emissions automatically. For those vehicles, smog checks are done by plugging into the car’s computer. But older vehicles don’t have that same technology—so dyno testing helps simulate real driving to get accurate readings. What We Look For During Testing During a BAR-97 dyno smog test , our certified technicians measure: Carbon monoxide (CO) Hydrocarbons (HC) Nitrogen oxides (NOx) If any of these levels are too high, your car may fail the test. But don’t worry—our team can help identify the cause, perform the needed repairs, and retest your vehicle to make sure it passes. Keep Your Classic or Older Car Legal and Reliable Passing your smog test isn’t just about staying legal—it’s also about keeping your car in top shape. A properly running engine burns fuel efficiently, saves gas, and helps protect our air quality here in Cathedral City and across California’s Coachella Valley. Schedule Your BAR-97 Smog Test Today If your car is older than a 2000 model year, it likely requires a BAR-97 dyno smog test. At Jim Brangham Auto Repair, we’re a STAR Certified Smog Check Station , and our team has the training and equipment to get your vehicle tested quickly and accurately. ✅ Call us today at (760) 321-7040 or click the Book Service button to schedule your dyno smog test and keep your car running clean and compliant.

When your power steering is working right, turning the wheel feels effortless. But if your wheel feels stiff or you hear a whining sound when turning, you may have low fluid or a worn-out pump. Why Low Power Steering Fluid Is Dangerous Driving with low or no power steering fluid can be unsafe. The pump needs that fluid to build pressure and help you steer. Without it, your wheel can become very hard to turn—especially when parking or driving slowly. That can make it harder to control your car in an emergency. Low fluid also causes damage inside the pump, since the fluid keeps it cool and lubricated. If the pump runs dry, it can wear out fast or even stop working completely. What could’ve been a small fix can turn into a much more expensive repair. The Difference with Electronic Power Steering Many newer vehicles use electronic power steering (EPS) instead of hydraulic. EPS uses an electric motor to help turn the wheels. These systems don’t need fluid and are more fuel efficient. Still, it’s important to have them checked now and then to make sure the sensors and motor are working correctly. Keep Your Steering Safe and Smooth No matter what kind of steering system your vehicle has, regular checks are important. If you notice stiff steering, whining noises, or see fluid under your car, don’t ignore it. At Jim Brangham Auto Repair in Cathedral City, CA , our ASE-certified team can inspect your power steering system, top off or replace the fluid if needed, and make sure everything is safe and working properly. Call Jim Brangham Auto Repair today at (760) 321-7040 to schedule your power steering inspection and service in Cathedral City, CA. We’ll help keep your car steering smoothly and safely for miles to come.

What the Differential Does The differential is what helps your wheels turn smoothly when you go around corners. It lets each wheel move at a slightly different speed, which makes driving easier and safer. If your differential starts to wear out, you might hear grinding or whining sounds, or feel your car handle differently. It’s one of those parts you don’t think about until something goes wrong — and by then, it can get expensive to fix. Why Differential Fluid Service Is Important Inside your differential is fluid that keeps the gears cool and lubricated. Over time, that fluid breaks down from heat, friction, and dust — especially in California’s desert weather. When the fluid gets dirty, it can’t protect the parts anymore. If that happens, it can cause: Rough or noisy driving Gear damage Leaks or vibration Costly repairs down the road That’s why changing your differential fluid on time is so important. It’s a simple and affordable way to keep your car running smoothly. How Often Should You Change It? Most cars need differential service every 30,000 to 60,000 miles. If you tow, haul heavy loads, or drive in hot weather often, you might need it sooner. The good news? It’s quick, easy, and saves you a lot of money compared to replacing the whole differential. How It Saves You Money Fresh differential fluid reduces wear and helps prevent breakdowns. A full differential replacement can cost thousands, while a fluid service is just a small routine maintenance. Taking care of it early keeps your car safe and reliable — and helps your budget in the long run.
