Arm Yourself With the Proper Tools, Equipment & Service Information to Facilitate Diagnosis and Repair
Getting a Grip on Traction Control
The basic principle of traction control is rather simple. A tire is breaking free and starting to spin so we’re going to place a drag on that wheel so that two things can happen. One is we want that tire to have a chance to regain its grip on the road surface. And two, we

Tech Tip: Silverado Owner Complains that ABS Light Comes on at 40-50 mph
At speeds over 40-50 mph, the ABS and brake indicators come on, and the fuel and volt gauges sometimes drop low at the same time. The technician had already verified the condition and checked for codes before calling Identifix. He found code C0237 (rear wheel speed signal erratic) stored as a history code, but it had not reappeared for him. Next he road-tested with a scanner, watching the vehicle speed input through the powertrain control module (PCM) and electronic brake control module (EBCM) data. When the ….
Diagnosing Wheel Speed Sensors
Wheel speed sensors (WSS) provide essential wheel speed information not only for anti-lock brake systems (ABS), but also for traction control and stability control systems. Some vehicles even compare the wheel speed sensor readings against the vehicle speed sensor (VSS) to make sure all of these sensors are accurate and working correctly. In some situations,
Truck Brake Update: Service Procedure Boosts Performance while Eliminating Steps that Add Time and Expense
Toyota trucks have been the standard bearer for small trucks for more than 40 years. The Hilux (now known as the Tacoma) line has been the small truck class leader, and over the last 15 years the T100 and Tundra models have moved into the medium- and full-size classes to set new standards there. With
ReFlashing Control Modules
You don’t have to be Microsoft A+ certified to flash reprogram automotive PCMs, but the process requires a certain amount of know-how as well as special tools and access to the latest OEM software upgrades. What’s more, it’s not a risk-free endeavor. Certain precautions must be undertaken before you begin, and there are pitfalls that
The ABS Phenomenon: Profitability Hinges on Solid Preventive Maintenance Program
Profitability Hinges On Solid Preventive Maintenance Program An unusual event happened last week: a customer actually wanted a glowing warning light on his anti-lock braking system diagnosed! A preliminary interview revealed that: a) the ABS warning light was continuously illuminated, b) the brakes pulled to the right, and, c) the brake pedal pulsated when pressure

Complete Brake Jobs
Restore Brake System Integrity For Better Performance And Safer Driving The rate at which the brake linings wear out depends on the frequency of use, how hard the brakes are being applied, the temperature of the linings and the wear characteristics of the friction material itself. Consequently, a set of brake linings on one vehicle
Suspension & Brake Repairs: Ensure Customer Service and Safe Vehicle Operation
This month, we find ourselves in a familiar environment — under a car or in the wheel well. The good news is you’re under a Mazda car or truck that will present few surprises in terms of service procedures, while providing the additional service opportunities we’ve come to expect from undercar repairs. A vehicle can
Replacing Hubs with Wheel Speed Sensors
By Larry Carley, Technical Editor When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside
