Duke's Guide to Vehicle Diagnosis


Hey, Duke here and you know going to your auto repair shop is a lot like going to the veterinarian or doctors when you have an issue with your vehicle.  It has to go through diagnostic tests before a solution or repair can be recommended.  So I am going to give you a guide on Vehicle Diagnosis so let's get barkin'.

Modern Los Altos 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 Los Altos drivers to track down the source of the problem.

To help your service advisor at Allied Auto Works figure out what's wrong, your vehicle is equipped with onboard 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 Allied Auto Works 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 Los Altos 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 Allied Auto Works in Los Altos depends on how much time it takes to sort out the symptoms and find the underlying problem.

Give us a call and tell them Duke sent ya.

Here is my diagnosis joke of the day for laughs,

I've just been diagnosed with Sausagephobia...

...I fear the Wurst.
