The Franklin Auto Service Guide to Vehicle Diagnosis

Modern Franklin vehicles have several computers on board that control all kinds of things like engine functions, transmission shifts, traction control, anti-lock brakes, stability control, emissions – and on some vehicles, even steering, braking and the throttle.

Think about that for a minute – things that used to be controlled by simple mechanical connections now have electronic controls that rely on computers, software and sensors. It's no wonder that when something goes wrong with their vehicle it can be pretty complicated for Franklin drivers to track down the source of the problem.

To help your service advisor at Franklin Auto Service figure out what's wrong, your vehicle is equipped with on-board diagnostics. The Check Engine light comes on to tell you there's a problem and the engine management computer stores a trouble code. Your friendly and knowledgeable Franklin Auto Service technician connects a scan tool to your vehicle's diagnostic port and retrieves the trouble codes as well as other important data.

Trouble codes are like clues for the technician to follow as he diagnoses what's wrong with your vehicle. In a way, it's like going to your Franklin doctor with a problem. She'll run some additional tests and gather the information she needs to make a diagnosis and form a treatment plan. How much a vehicle diagnosis costs at Franklin Auto Service in Franklin depends on how much time it takes to sort out the symptoms and find the underlying problem.

When Do My Shocks Need to Be Replaced?

A good suspension system gives a vehicle a smooth, even ride while providing Franklin drivers with good handling and control. But like any system on your vehicle, parts of the suspension system can wear out, leading to a lower ride quality and safety concerns. So it's a good idea for drivers in Franklin to remember their suspension system in their schedule of preventive maintenance. Springs do most of the work of the suspension system. The most common types of springs are coil and leaf, but air springs and torsion bars are becoming more common. The body of the vehicle is “suspended” by the springs.

If springs were the only working component in your suspension system, however, you'd spend your travel time bouncing up and down like a bobblehead. That's where your shocks come in. They keep the rebound, or bounciness, of the springs under control. Shocks also keep your tires on the road, which keeps the driver in control of the vehicle. Some vehicles have struts in their suspension system. Struts are a compact combination of springs and shocks. They do the same job but in a single package.

Shocks wear out gradually, so it can be difficult for Franklin drivers to notice when they need to be replaced. There's no definitive point when a vehicle's ride goes from "smooth and controlled" to "a bit imprecise." To check if your shocks or struts are worn, you should first do a visual inspection on them. If they are leaking fluid, they need to be replaced.

There are other less obvious signs that your suspension system needs attention. For example, an uneven, cupping wear on your tires may indicate that your shocks are worn. If your vehicle feels “floaty” when you turn, or, in other words, you don't feel that you have full control of the vehicle, you should check your shocks. Also, if the front end of your vehicle dips noticeably when you stop, it's time for new shocks.

Your owner's manual gives recommendations on how often the shocks should be checked, usually between 15,000 and 30,000 miles (24,000-50,000 km). If one of your shocks does need to be replaced, you should replace all four. This will keep your suspension even and ensure good handling of your vehicle. If you carry heavy loads, tow a trailer or drive on uneven Franklin area terrain, you might also consider upgrading to a heavy-duty shock.

Regular shocks contain hydraulic fluid. The fluid helps them absorb the bumps or “shocks” of the road so the impact doesn't transfer to the vehicle's body. Premium shocks are filled with compressed nitrogen gas, which costs more but does a better job of controlling body motions. Regular shocks can develop air bubbles that reduce their effectiveness; the premium shocks don't have this problem. So if you want higher handling performance, if you drive off-road around MI or if you just want added comfort, you should consider upgrading to premium shocks or struts.

Replacing struts can put your vehicle out of alignment, so an alignment check should always follow this type of repair. Talk to your service advisor at Franklin Auto Service in Franklin for more information.

Franklin Auto Service Engine Air Filter Replacement

When your experienced Franklin Auto Service technician changes your oil, he will also inspect your air filter. You shouldn't need a new air filter at every oil change, but you will need to change it regularly. Heed your technician's auto advice if they tell you to change your air filter.

An air filter does what its name implies: it filters stuff out of the air. Air is drawn into your engine through the filter because your engine needs air to burn fuel. If the filter weren't there, a lot of dust and debris would come into the vehicle engine with the air when you are driving around Franklin. That dust and debris would get hot, burn and produce all kinds of ash and gumminess that would eventually clog up your engine.

Drop in an air filter and voilá! Problem solved.

But air filters themselves get clogged up with all the junk they clean out of the Franklin air. This doesn't allow the junk into the vehicle engine, but it does block up the airflow. A blocked airflow will reduce engine efficiency.

Franklin residents who get a charge out of the feeling of power in their engine might consider upgrading their air filter. Talk to your friendly and knowledgeable Franklin Auto Service service advisor. Premium air filters have been proven to increase horsepower and torque. So with the cost of a premium air filter, you can increase the horsepower in your engine — there's no cheaper way to do that!

It's also one of the simplest elements of routine preventive maintenance – and it protects against damage to expensive vehicle electronic systems. No Franklin resident should have an excuse to drive around MI roads and highways with a dirty air filter.

New School: Automotive Franklin Auto Service Technician Training

Franklin consumers are demanding. We want a safe, reliable vehicle that handles well and is comfortable to ride in. Oh, and we want good fuel economy, too. We also want vehicle repairs that are cheap, fast and easy. Unfortunately, one usually comes at the cost of the other.

Today's vehicles have made significant improvements in reliability and performance over the last few decades. They also deliver more power to Franklin drivers more efficiently than ever before. For example, some of today's 4-cylinder engines are equal to yesterday's V-8's. Our vehicles also offer an amazing range of features that make them more comfortable and convenient than ever before.

But all of that improvement has come at a price for Franklin vehicle owners. Our vehicles are more complicated and difficult to repair than ever before. They have numerous mechanical and electrical systems. Fuel systems are so complex they have to be run by a computer. Our vehicles are covered with sensors and high-tech electronic equipment. Our dashboards rival the control panel of the first manned space flight.

With all that complicated equipment, it's no wonder we call mechanics service technicians these days. You can't learn to repair vehicles in the backyard with your dad anymore. Today's Franklin Auto Service technicians have to go to school. School may come in the form of classroom instruction, online courses or both. Technicians are also trained on-site at the Franklin service centers where they work (including Franklin Auto Service) to keep them abreast of constant improvements in vehicle engineering, diagnostic equipment and repair techniques.

Today's technicians need to be certified to work on our vehicles. They can earn a variety of certifications in MI, but the highest of these is Master Technician. It's like a graduate degree in auto repair.

Vehicle repair at Franklin Auto Service in Franklin requires more than just training and certification, though. It also takes information and creative thought. Franklin area auto service centers subscribe to data services, technical libraries and online repair communities in order to get the information they need to: work on various makes and models of vehicles, get recommended maintenance schedules, learn about non-standard features and locate hard-to-find parts in an unusual engine. They also use this information to help diagnose rare or difficult vehicle problems. Many auto repair problems also require a bit of creative thinking for the team at Franklin Auto Service to solve. Franklin service technicians at Franklin Auto Service act much like doctors in these situations. They're given a set of symptoms, and they have to come up with a diagnosis and treatment that will fix the problem. This process becomes as much of an art as it is a science.

A proper diagnosis, even by a highly qualified technician, can take time. And a technician's time is going to cost us. It's just the price of progress.

Of course, the best vehicle care for Franklin vehicle owners is planned preventive auto maintenance. This is also the least costly way to keep your vehicle in good repair. Regular inspections and replacement of worn parts will prevent most repairs from ever being needed in the first place.

And with the amazing complexity of today's automobiles, isn't it good to know there's someone out there with the knowledge, training and skill to give us good auto advice? Whether we need preventive maintenance or repairs, the team of automotive professionals at Franklin Auto Service can help us keep our vehicles on the road. We just can't do it on our own anymore.

The Sign of the Shield (Heat Shield Repair and Replacement)

Even in the months where temperatures are cooler, heat is still an enemy of your vehicle.  When your engine runs, it creates heat, so there are numerous heat shields that protect other parts from those higher temperatures. Heat shields are installed around several areas of the exhaust system.  Others prevent heat from reaching parts of the vehicle.  Still others prevent heat from reaching the ground (or maybe grass underneath) and starting a fire. 

If you remember your space travel history, you'll know how important a heat shield can be. John Glenn was the first American to orbit the earth, but during that maiden orbital flight, a sensor on board was indicating the heat shield on his capsule, Friendship 7, was loose.  If it had come off, his spacecraft could have burned up upon re-entry.  Fortunately, the heat shield stayed on, and Glenn made history.

Unfortunately, the heat shields on your vehicle don't have warning systems like the space vehicles did.  So you have to maintain them.  Heat shields are constantly exposed to elements like water, salt, sand and dirt.  That makes them prone to rusting and corroding.  Here's one unfortunate fact: Materials that make them good at preventing heat transmission also are soft and vulnerable, often aluminum or special fabric. 

One sign a heat shield will give you that it's loose is noise; you'll sometimes hear it rattling underneath your vehicle when it's running. One way to locate it? Put your vehicle in park, leave the engine running and take a listen outside.  It's usually pretty easy to pinpoint the location.

Make a note of the noise when you are talking with your service advisor. It's important to have those heat shields working correctly so the heat is kept away from your other vehicle systems and combustibles on the ground. The good news is that heat shields can frequently be inexpensively repaired or re-attached.  In other cases, they should be replaced. 

Missing or loose heat shields? Let's just say they're not cool.
