Tech Feature: The Future of Steering
The Steering System on light vehicles is one of the most critical interfaces between the road, vehicle and driver. The nature of this interface has remained virtually the same for most of the life of the automobile. Somewhere early one it was decided to upgrade the old "tiller" steering system with the traditional wheel. With all the activity in the industry that challenges the assumptions of current vehicle systems what is the future for steering systems?
Tech Tip: Diagnosing and Servicing Automatic Transmissions
Automatic transmissions and transaxles fall into two categories: mechanical and electronic. Older vehicles with mechanical automatics use engine speed, throttle cables, governors and valves to shift gears. Newer vehicles with electronic transmissions use engine RPM and sensor inputs to operate solenoids that route internal fluid pressure to shift gears.

There’s No Escaping Hybrid Service
high as 40 mph (64 kph). Plus, when conditions are right, the engine may shut off at stops and not restart until after 25 mph. As a result, the advertised fuel economy of a full hybrid vehicle is typically much higher for the city driving conditions than the highway driving conditions. In theory, assuming the
Tech Tip: Pointers for Inspecting Brake Systems
Brake linings are sacrificial components designed to convert kinetic energy into heat energy by rubbing against a rotating brake rotor or drum. This rubbing action or friction wears away a miniscule portion of the brake lining and rotor or drum each time the brake pedal is applied.
Tech Tip: Light Braking Causes ABS Modulation
During light braking on Acura vehicles, a wheel sensor that detects a faulty or intermittent low-speed signal can make the ABS control unit "think" the affected wheel is turning slower than the rest. To make all wheels turn at the same speed, the ABS then modulates the brake fluid pressure to that wheel, causing the pedal kickback to be felt with normal ABS activation.
Hybrid Engine Diagnosis & Service
The Toyota Prius and Honda Insight hybrids have been around since 2001; the Honda Accord, Ford Escape and Lexus RX 400h hybrids since 2005; the Honda Civic, Toyota Highlander, Mercury Mariner, Chevrolet Silverado and GMC Sierra hybrids since 2006; and the Lexus GS 450h, Saturn VUE Green Line, Toyota Camry and Nissan Altima hybrids since
Foreign Affairs: Probing Around Subaru Electrical Systems
With station wagons, small multi-purpose trucks and high-powered sports models in its product mix, Subaru has become an obvious choice for multi-use purchasers. And, by building one basic platform with all of the right stuff, Subaru has been able to concentrate on quality. That brings us to the topic of this article, Subaru electrical systems.
Toyota Tech Tip: Replacing the Rear Bearing O-Ring
When replacing the rear hub bearing assemblies on 1997-2001 Camrys, 2000-2002 Avalons produced before VIN 4T1BF28B#2U223623 and 1999-2002 Solaras produced before VIN 2T1##2#P#2C005335, it’s necessary to replace the O-ring.
Tech Tip: Top 10 Domestic Diagnostic Codes and Fixes
A Check Engine Light that’s illuminated is always a sign that something is wrong. But what? You usually can’t tell until you plug in a code reader or scan tool and read out the code(s) that have turned on the light. At least then you have a starting point for further diagnosis. Some people think a code is all you need to fix a fault and turn off the Check Engine Light. A diagnostic trouble code certainly helps, but it only tells you that some kind of fault has occurred, and maybe the circuit or component associated with the fault.
