Cayenne's On Board Diagnostics For Los Altos Motorists

CAY

Cayenne here,

Some Los Altos drivers wonder why Allied Auto Works and other Los Altos auto repair shops charge a fee for diagnostic services.

Think about it: When you hire a local Los Altos HVAC technician to check out a problem with your air conditioner you’ll probably pay a diagnostic fee. When you visit your Cupertino doctor for a health problem, you pay the physician to diagnose the ailment and of course for the tests that go along with it.

On Board Diagnostics For Los Altos Motorists

So receiving a diagnostic charge at Allied Auto Works for a tricky automotive problem shouldn’t be a surprise. In the Los Altos area, automotive diagnostics can cover quite a range. If you hear a noise in your sedan brakes when you slow down in rush-hour traffic on a busy CA interstate, 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 sedan engine, however, Allied Auto Works diagnosis may be much more involved.

Much of the Los Altos auto 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 Cupertino, Sunnyvale, and Mt. View drivers that the trouble code tells the Allied Auto Works 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 sedan computer's trouble code just tells the Allied Auto Works 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 Allied Auto Works customers. The Allied Auto Works service advisor makes a list of the most likely causes and begins tracking down the source of the problem. This takes time.

Los Altos 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 vital 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 Allied Auto Works wants to figure out what’s wrong with your sedan and get you back on the road as quickly as possible.

Well I hope that clears up any mystery about Diagnostic for today and until next time this is Cayenne your friendly dog blogger
