Searching for the Diagnostic Path
November 01, 2004 Most recently, I've found myself dealing with an increasing number of random, multiple-code complaints that involve computer operating strategies and networking communications issues in which the multiple trouble codes or DTCs tend to be symptomatic, rather than indicative, of a component failure. A basic illustration of what I'm talking about is a simple DTC 44, which is a trouble code for OBD I General Motors products indicating a lean air/fuel ratio. In reality, the DTC 44 may not be indicating a lean air/fuel ratio as much as it's indicating that the oxygen sensor itself is out of calibration. This process of making sense out of multiple and sometimes contradictory data often becomes what I call "." Time, Money and Probability |

Taking the Scare Out of Auto RepairPresented by the Federal Trade Commission, the National Association of Attorneys General and the American Automobile AssociationThe best way to avoid auto repair rip-offs is to be prepared. Knowing how your vehicle works and how to identify common car problems is a good beginning. It's also important to know how to select a good technician, the kinds of questions to ask, and your consumer rights. According to the Federal Trade Commission (FTC), the American Automobile Association (AAA), and the National Association of Attorneys General (NAAG), this kind of information about your automobile may help you keep a lid on mechanical mistakes. REPAIR INFORMATIONHow to Choose a Repair ShopWhat should I look for when choosing a repair shop?
How to Choose a TechnicianIs one technician better than another?
Repair Charges: Unlocking the MysteryBefore you arrange to have any work performed, ask how the shop prices its work. Some shops charge a flat rate for labor on auto repairs. This published rate is based on an independent or manufacturer's estimate of the time required to complete repairs. Others charge on the basis of the actual time the technician worked on the repair.If you need expensive or complicated repairs, or if you have questions about recommended work, consider getting a second opinion. Find out if there will be a diagnostic charge if you decide to have the work performed elsewhere. Many repair shops charge for diagnostic time. Shops that do only diagnostic work and do not sell parts or repairs may be able to give you an objective opinion about which repairs are necessary. If you decide to get the work done, ask for a written estimate. What should a written estimate include?

HEADING OFF PROBLEMSThe more you know about your vehicle, the more likely you'll be able to head off repair problems. You can detect many common vehicle problems by using your senses: eyeballing the area around your vehicle, listening for strange noises, sensing a difference in the way your vehicle handles, or even noticing unusual odors. Looks Like TroubleSmall stains or an occasional drop of fluid under your vehicle may not mean much. But wet spots deserve attention; check puddles immediately. You can identify fluids by their color and consistency:
Smells Like TroubleSome problems are under your nose. You can detect them by their odor:
Sounds Like TroubleSqueaks, squeals, rattles, rumbles, and other sounds provide valuable clues about problems and maintenance needs. Here are some common noises and what they mean: Squeal - A shrill, sharp noise, usually related to engine speed:
Click - A slight sharp noise, related to either engine speed or vehicle speed:
Screech - A high-pitched, piercing metallic sound; usually occurs while the vehicle is in motion:
Rumble - a low-pitched rhythmic sound.
Ping - A high-pitched metallic tapping sound, related to engine speed:
Heavy Knock - A rhythmic pounding sound:
Clunk - A random thumping sound:
Feels Like TroubleDifficult handling, a rough ride, vibration and poor performance are symptoms you can feel. They almost always indicate a problem. Steering
Brake problems have several symptoms. Schedule diagnosis and repair if:
The following symptoms indicate engine trouble. Get a diagnosis and schedule the repair.
Poor transmission performance may come from actual component failure or a simple disconnected hose or plugged filter. Make sure the technician checks the simple items first; transmission repairs normally are expensive. Some of the most common symptoms of transmission problems are:
TROUBLE SHOOTINGCar trouble doesn't always mean major repairs. Here are some common causes of trouble and techniques to help you and your technician find and fix problems:
