Modern Glendale Heights vehicles have several computers on board that control all kinds of things like engine functions, transmission shifts, traction control, anti-lock brakes, stability control, emissions – and on some vehicles, even steering, braking and the throttle.
Think about that for a minute – things that used to be controlled by simple mechanical connections now have electronic controls that rely on computers, software and sensors. It's no wonder that when something goes wrong with their vehicle it can be pretty complicated for Glendale Heights drivers to track down the source of the problem.
To help your service advisor at Tuffy Tire & Auto Service Glendale Heights figure out what's wrong, your vehicle is equipped with on-board diagnostics. The Check Engine light comes on to tell you there's a problem and the engine management computer stores a trouble code. Your friendly and knowledgeable Tuffy Tire & Auto Service Glendale Heights technician connects a scan tool to your vehicle's diagnostic port and retrieves the trouble codes as well as other important data.
Trouble codes are like clues for the technician to follow as he diagnoses what's wrong with your vehicle. In a way, it's like going to your Glendale Heights doctor with a problem. She'll run some additional tests and gather the information she needs to make a diagnosis and form a treatment plan. How much a vehicle diagnosis costs at Tuffy Tire & Auto Service Glendale Heights in Glendale Heights depends on how much time it takes to sort out the symptoms and find the underlying problem.
