On Board Diagnostics for Livonia Motorists

June 25, 2018

Some Livonia vehicle owners wonder why Elite Tire And Auto Care and other Livonia auto repair shops charge a fee for vehicle diagnostics.

Receiving a diagnostic charge at Elite Tire And Auto Care for a tricky automotive problem shouldn't be a surprise. In the Livonia 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 Michigan 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 Elite Tire And Auto Care diagnosis may be much more involved.

Much of the Livonia 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 Michigan drivers that the trouble code tells the Elite Tire And Auto Care 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 Elite Tire And Auto Care 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 Elite Tire And Auto Care customers. The service advisor makes a list of the most likely causes and begins tracking down the source of the problem. This takes time.

Livonia 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 Elite Tire And Auto Care wants to figure out what's wrong with your vehicle and get you back on the road as quickly as possible.
