On Board Diagnostics for Tucson Motorists

Posted July 12, 2020 4:48 AM

Some Tucson vehicle owners wonder why AASTRO Transmission & Auto Repair and other Tucson auto repair shops charge a fee for vehicle diagnostics.

Receiving a diagnostic charge at AASTRO Transmission & Auto Repair for a tricky automotive problem shouldn't be a surprise. In the Tucson area, automotive diagnostics can cover quite a range. If you hear a noise in your vehicle brakes when you slow down in rush-hour traffic on a busy AZ road, you pull off at 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 vehicle engine, however, a AASTRO Transmission & Auto Repair diagnosis may be much more involved.

Much of the Tucson driver'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 AZ drivers that the trouble code tells the AASTRO Transmission & Auto Repair 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 vehicle computer's trouble code just tells the AASTRO Transmission & Auto Repair 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 AASTRO Transmission & Auto Repair customers. The service advisor makes a list of the most likely causes and begins tracking down the source of the problem. This takes time.

Tucson 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  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 AASTRO Transmission & Auto Repair wants to figure out what's wrong with your vehicle and get you back on the road as quickly as possible.
