The Byte Stuff (Your Vehicle's Computers)

Nobody has to tell you that computers are a part of so many things in our lives.  Smartphones, kitchen appliances, vacuum cleaners, televisions.  You name it—it has a computer in it.  And your vehicle is no exception.

The earliest cars relied on the technology of their time, and there was no such thing as a computer.  But now, it's not unusual for a vehicle to have as many as 150 computers in it.

They perform a variety of functions. An important one is diagnosing your vehicle's problems.  There are various sensors throughout modern vehicles that measure thousands of data points.  When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car.  It displays certain codes that help technicians track down the culprit. 

But it's not just the diagnostics that are computerized.  Everything from your vehicle's fuel injection to anti-lock brakes is.  Convenience features such as power windows, rain-sensing windshield wipers, a wi-fi-hot spot, streaming video and navigation are all sophisticated computers.  Then there are the safety features; air bags, traction control, automatic emergency braking and a host of others are all dependent on computers.

It is important that those computers work correctly because they interface with many of the other computers on board.  To properly diagnose problems with those computers requires training and special equipment. Your service facility has invested considerable resources into both, and they are equipped to properly evaluate and repair and/or replace malfunctioning components. 

Some lament the days when backyard mechanics could pull out their tools and do their own repairs.  Those days are fast disappearing with the computerization of vehicles.  But look at the bright side.  Your vehicle does so much more, has so many more features and travels far more safely than those past generations drove.  And they're bound to get better and more sophisticated down the road.

For 4x4s (Maintenance of 4x4 Vehicles)

Some people love 4x4 vehicles, the true 4-wheel drive works of engineering like Jeeps and 4x4 pickups that allow you to seemingly go anywhere on the planet. You can climb up a 40-degree rock trail with some planning and skill (always careful to protect the environment, of course), or you can get through the deepest snow.

But with that added capability comes additional complexity, drive-train components and other systems that less capable vehicles don't have.  And that is why when it comes to 4x4s, you have to maintain them a little differently from those vehicles that spend their lives on pavement.  Here are some of the key things to keep an eye on:

• Transfer case—This transfers power from the engine to the wheels.  A transfer case has fluid in it that needs to be changed at intervals recommended by the manufacturer.  Your service advisor will let you know how often that is and will keep track of your service dates.  You will need to make sure the transfer case seal is working properly.  Otherwise, transmission fluid could get in and cause damage that is costly to fix.  Some transfer cases have an electric motor that shifts it through gears, and its connections are often exposed to the elements, making them vulnerable to damage and corrosion.  Proper maintenance will keep those connections working like they should
• Front and rear differentials—These also have to have the right amount of fluid and should be checked regularly.  Your service advisor can let you know when you need that fluid changed as the owner's manual recommends.  It's important the service is performed correctly with the proper lubricant so it will work the way it is designed to.
• Brake lines—Those 4x4s practically beg to go into wet spots. They also are great machines to conquer snow: road salt, brine and all.  Moisture, salt and brake lines are a recipe for corrosion, so brake lines need to be inspected regularly.  There are anti-corrosion sprays or white lithium grease that can retard corrosion.  Remember, getting there is half the fun, but not being able to stop is no fun at all.

So enjoy your 4x4 and what it can do that other vehicles can't.  Just remember that even though it's tough on the outside, it needs special care to keep it going.  Oh, and remember to take care of the environment when you go off-roading, too. 

Poor Reflections (Door Mirror Problems)

Mirror, mirror on the door, why is my vision there so poor? Well, you could have a broken outside rearview mirror that's disabled your blind spot vision there and endangering your ability to see some of the traffic around you. 

Outside rearview (or door) mirrors are important safety devices that are thoughtfully designed to help drivers see.  And there are a variety of ways those door mirrors can develop problems.

One is when the glass is broken in them.  Sometimes it's caused by an accident or vandalism.  But without your ability to see in that mirror, you could be driving blind, unable to see drivers approaching from the rear in adjacent lanes.  Sometimes it's as simple as having the glass replaced.  You'll greatly enhance your safety if you do.

Then there's the door mirror that you can't adjust.  First, let's look at a common scenario in later models, the power mirror.  They're great when they're working, awful when they're not.  Sometimes the motor fails, the switch goes bad or the wiring fails to deliver power.

Or how about the manually-adjusted door mirror that has either frozen up or just flops around? In this case, the mechanism has corroded, jammed up or a part has broken.  In both power- and manually-adjusted door mirrors, it sometimes can be hard to keep them in the right position.  Plus, every time there's a driver change, it may be hard to adjust those broken mechanisms by hand.

Finally, heated door mirrors can be extraordinarily useful in eliminating fogging or icing up in certain weather conditions.  But those heating elements can fail, switches can break or wiring can go bad.  Suddenly your fogged over, frozen mirrors aren't doing you any good at all. 

Good drivers use those outside rearview mirrors all the time.  They should be working the way designers intended, to provide the driver with vital traffic position information.  That's the kind of safety device you should get fixed or replaced sooner rather than later.  It's well worth it if you prevent even one little accident.
