Things Aren't Always What They Seem

If you drive, you know at some point, something's going to go wrong with your vehicle.  And sometimes, it's pretty easy to figure out what's wrong, like a flat tire.  But sometimes your vehicle's symptoms can be really puzzling. One driver in CA was heading to work on a hot July day and noticed when he pressed the accelerator, sometimes it wouldn't do anything. He also noticed his cruise control wouldn't work and his traction control light was constantly on, very unusual. He was trying to figure it out, but none of it made any sense.  His cruise control had always worked perfectly, his traction light never had gone on before and there was never any issue pressing on the accelerator. It was time to take his car in for a professional diagnosis, and boy, was he surprised that it was a freak accident he'd had the previous WINTER that was the root of his problems.  You see, in January, his car had slipped on ice when he was in reverse and had gently tapped a tree.  ... read more

On Board Diagnostics for Your Engine

Starting in 1996, John's Automotive Care service technicians have been able to use a standardized diagnostic system to help determine what is wrong with a vehicle. This diagnostic system works in tandem with the Engine Control Modules for each vehicle's engine. The Engine Control Module is a computer that monitors and controls many engine functions.Sensors throughout a vehicle send readings to the Engine Control Module. These readings help the computer make adjustments in various vehicle systems to allow for constantly changing driving conditions and even to compensate for minor problems. However, if the computer encounters a situation it can't adjust for, it turns on the Check Engine light. (The Check Engine light is called the “service engine soon” light on some vehicles.)If the Check Engine light is burning steadily, it indicates a problem that needs to be taken care of soon. If it is flashing, however, the vehicle needs ... read more

The John's Automotive Care Guide to Vehicle Diagnosis

Modern San Diego 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 San Diego drivers to track down the source of the problem.To help your service advisor at John's Automotive Care 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 John's ... read more

Automotive Detective Work in San Diego

There's a reason we use the word “diagnose” when we talk about fixing cars in San Diego. Figuring out what's wrong with your vehicle has a lot of similarities to figuring out what's wrong with someone who is ill. Vehicles are a mass of complex systems that can produce a variety of symptoms when something goes wrong. As with human diagnoses, a specific symptom may be indicative of a number of problems, and figuring out the specific cause takes training and experience.Sometimes the diagnosis of your vehicle's trouble comes down to a matter of trial-and-error. This can be frustrating for San Diego drivers because time and money are on the line. You may feel you should only be paying for repair work. Of course, you only want to pay for the right repair – and a proper diagnosis is part of getting it right. Like at the doctor's office — some of what you pay for is the doctor's time and effort to figure ... read more
