Artificial Intelligence And Communication At CES 2017

The single biggest disruptor in our world right now is the evolution of cars. Specifically, technological advancements in the areas of communication and computing offer some of the biggest opportunities our industry has ever seen.

Automotive Electrical Diagnostics

Electricity can be measured and observed at the source, but the technician has to be able to visualize electricity and how resistance, amperage and voltage change its flow. This can require some imagination, or in some cases, faith. Regardless, the math has to add up.

Modern Vehicle Diagnosis And Repair

Even with all these modern tools, techniques and scanners, there are still problems that occur because of previous work performed incorrectly. The difference is how the computers in modern cars interpret incorrect parts or faulty workmanship.

Driveshaft Diagnostics and Service

Driveshaft problems can be spotted from the moment you put the vehicle in gear to pull it into a bay. As the power is transmitted from the transmission to the rear axle, the slack from worn or damaged components is taken up, resulting in a sudden crunch or pop.

Remote Diagnostics On Cars: The Future, or Future Headache?

When I talk to technicians and shop owners about “remote diagnostics,” I find that there are many different levels of understanding as to what that term means. It’s clear that for many, the perception is that remote diagnostics means the ability to read codes. Well, if that is all we are talking about, it is true that a number of cars can generate a health report that includes things like DTCs, mileage and oil life.

Car Diagnostics And Testing: Proper Shop Procedures

Close isn’t good enough if you want to establish credibility in your local market. Today’s professional technician can’t just grab a component hanging from a branch of the proverbial parts tree and see if that will fix the problem. It requires a diligent effort of testing and diagnostic time to analyze the maze of electronic data.

Power Steering Dynamics And Diagnostics

Twenty-five years ago, when the power steering failed, diagnosing the system was easy. The most difficult problem to diagnose was the “morning sickness” that plagued some vehicles when they were cold. Today, the introduction of speed sensitive steering, electric power steering and computer controls have made power steering diagnostics more demanding.

Winter Air Ride Diagnostics

To the untrained technician, a winter air ride problem might lead you down the path thinking there is a leak in the system. However, chances are there are no detectable leaks. These types of faults are usually set by parameters from the air ride module for a certain action to cause an expected result. Think of it as an EVAP system.

Electric Power Steering Diagnostics

Electric power steering is more energy efficient than hydraulic systems and does not provide assist until it receives driver input, but there are differences in the hydraulic and electric assist that will affect the driver’s and technician’s understanding of the component and its integration into the ESC and self-park system.

EPB Diagnostics

A growing number of vehicles are equipped with EPB (electronic parking brakes). This article discusses diagnostic approaches for servicing these systems.

Oxygen Sensors: Pulse Measurement

Watching an oxygen sensor output on an oscilloscope is like watching a sporting event on television. You get to see the action, but can do nothing about it as it happens. Sometimes you miss the action and want an instant replay. It was a bad call. You saw the interference. If the referee didn’t see
