On Board Diagnostics For Des Moines Motorists
Some Des Moines motorists wonder why Des Moine BDG and other Des Moines auto repair shops charge a fee for diagnostic services.
Think about it: When you hire a local Altoona HVAC technician to check out a problem with your air conditioner you’ll probably pay a diagnostic fee. When you visit your Ankeny doctor for a health problem, you pay the physician to diagnose the ailment and of course for the tests that go along with it.
So receiving a diagnostic charge at Des Moine BDG for a tricky automotive problem shouldn’t be a surprise. In the Altoona area, automotive diagnostics can cover quite a range. If you hear a noise in your minivan brakes when you slow down in rush-hour traffic on a busy IA expressway, you pull off the next off-ramp and take a quick visual check. That is usually enough to know what needs to be done. If you’re having an intermittent problem with your minivan engine, however, Des Moine BDG diagnosis may be much more involved.
Much of the Altoona car owners’s confusion comes when the problem involves the check engine light. The check engine light comes on when the engine management computer has sensed a problem.
There’s a common misconception among Ankeny, Berwick, and Grimes drivers that the trouble code tells the Des Moine BDG technician exactly what’s wrong. They wonder why there is a diagnostic charge – because the scanner quickly gave the diagnosis.
In reality, it is not that easy and straightforward. The computer monitors many sensors throughout the vehicle. When one of these sensors has a reading that’s out of parameters, the computer will record a trouble code and turn on the check engine light.
The minivan computer’s trouble code just tells the Des Moine BDG technician what engine parameter is out of range – not what’s causing it. The technician needs to determine the underlying problem that’s causing the malfunction.
There are many problems that could cause a troublesome sensor reading for Des Moine BDG customers. The Des Moine BDG service advisor makes a list of the most likely causes and begins tracking down the source of the problem. This takes time.
Altoona service centers subscribe to databases that document possible causes for all the possible trouble codes. The databases outline procedures for confirming a diagnosis and provide the documented repair. These key databases are specific to each vehicle and engine combination.
Some diagnoses are quick and easy. Others are more involved, time-consuming, and difficult. Of course Des Moine BDG wants to figure out what’s wrong with your minivan and get you back on the road as quickly as possible.
