I do like the Tappet Brothers. I like to challenge myself and "play" along with them trying to guess the problem too.<br /><br />Darcy has realized with all the times I've come across a problem that cars are not as easy to diagnose as she thought. She believed it to be exactly as you said - that the diagnostic scanner tells you what to fix and that's it. It's not that simple. The scanner tells the mechanic what is out of specification, however, there can be many causes for that fault.<br /><br />Darcy has equated fixing cars to doctors practicing. You rule out the easiest and most likely causes first until you find the problem or rule out everything else.<br /><br />I recently had a car come in that didn't have a code, yet it wouldn't start, long story short, it took me 3 days to rule out the different possibilities until I determined the computer itself as bad.<br /><br />In another case, the code may say the oxygen sensor is reading the exhaust as being lean (which means it's reading an abundance of oxygen). This could be caused by the sensor being bad, a faulty injector, a faulty spark plug, a faulty distributor, a worn engine or a number of other conditions. Most people will replace the oxygen sensor and when that doesn't solve the problem, they wonder why.<br /><br />If the customer doesn't complain of any other problems, I will only check the most basic items. Fluids, brakes, belts, suspension. This are maintenance items that need to be kept up on. Any other problem will only be checked if there's a reason to check it.<br /><br />People are already leery of mechanics that fix problems that haven't become a problem yet. Without a reason to check, it seems a little suspicious.<br /><br />I had more to say but after being interrupted by dinner, I've lost most of my train of thought.Bruce Changhttp://www.facebook.com/greasemonkeyv2.0noreply@blogger.com
