Rather than covering programming and relearn procedures, a subject that has been addressed in select previous issues, this article focuses on common (and uncommon) concerns that a technician may encounter, along with tips to avoid mistakes. Here, we’ve enlisted the expert advice from some of the leading tire pressure monitoring system (TPMS) sensor and tool makers.
Today’s wheel bearings, like many other components, have become so dependable that we don’t pay much attention to them until there is a complaint. The typical wheel bearing grumbles are about strange noises, rumbling feelings or an anti-lock brake (ABS), electronic stability control (ESC) or traction control system (TCS) system light or issue.
Most of the normal service and repair required by a hybrid vehicle is the same as other cars. They all need fluid changes and brake service, they all have oxygen sensors and EVAP systems and they use the same generic OBD-II fault codes as their non-hybrid cousins.
Ah, the lowly fender cover. It was born with a single life mission: to protect the painted surface of a front fender from nicks and scratches while underhood work is being performed.
Let’s take a look at various suspension parts inspections, including ball joints, wheel bearings, wheel hub units, control arm bushings and more.
General Motors’ EcoTec3 family of engines is a familiar sight under the hoods of many GMC and Chevrolet pickup trucks and SUVs. It is available in three versions: 4.3 V6, 5.3 V8 and a 6.2 V8. General Motors debuted this new engine design on the 2014 model year trucks and although the 6.2 V8 versions look comparable to the GEN 5 V8 LT of the Corvette and Camaro, they are uniquely individual engines.
Vehicles enter the shop. Some customers require routine maintenance. Some customers complain about driveability issues. The brakes squeal. They hear a clicking noise on turns. The engine cranks but won’t start. The tires are wearing out fast. The car pulls to the left under braking. The engine is leaking oil. The list goes on.
In 2014, Fiat Chrysler began filling the air conditioning systems on almost all of its models with R1234yf refrigerant. That same year, General Motors (GM) began using it in the Cadillac XTS. Since then, GM has been gradually switching over its entire line of vehicles to R1234yf, and Ford has also begun using it, too.
Premium-priced high-performance luxury cars tend to push the envelope in terms of braking system performance. While a disc/drum or disc/disc system found on any production vehicle is designed to provide safe and reliable braking, luxury performance cars tend to be outfitted with “spirited” driving in mind. As engine power increases, accompanied by the potential for higher speed operation, there’s more demand on the brake system, requiring the system to meet these challenges.
We can’t possibly have all the tools that we need to repair every vehicle that comes into our shop, even if we concentrate on only a couple of makes or manufacturers. There are simply too many dedicated tools required today to perform all of the required tasks on today’s engine, transmission and drivetrain systems. Even a simple water pump service can now require highly specialized tools, but dealing with a check engine light doesn’t always require the factory scan tool, even if you have one available.
