Ryan Newman Crew Chief Matt Borland Grabs Lead In Race For $100,000 MOOG ‘Problem Solver Of The Year’ Award
Ryan Newman crew chief Matt Borland grabbed the lead in the race for the $100,000 MOOG Steering and Suspension “Problem Solver of the Year” Award after the No. 39 Quicken Loans Chevrolet SS picked up 21 positions and improved by a race-high 0.203 seconds in the second half to finish third in Saturday’s Federated Auto Parts 400 at Richmond (Va.) International Raceway. Borland left Richmond with his fourth MOOG “Problem Solver of the Race” Award, giving him a one-win advantage over Joey Logano (No. 22 Ford) crew chief Todd Gordon in the battle for the most prestigious year-end honor for NASCAR Sprint Cup series pit professionals.
Tech Tip: Generation 1 Wheel Bearings With Integrated ABS Tone Ring
The front wheel bearings listed in this Tech Tip all share a unique design feature. They are all double-row angular contact with a split inner ring. The distinctive feature on these bearings is that one of the two seals on the bearing has a built-in magnetic impulse wheel. Caution should be taken to make sure that the seal with the ABS impulse ring is installed in the correct direction.
ABS + ESC: Diagnosis of Accelerometers and Yaw Sensors
Accelerometers measure gravitational pull in gravitational force or G-force. Some cars will have one or two sensors depending on sophistication of the system.
ABS/ESC Brake Solenoid Diagnostics
The ABS computer or HCU is a node on a high-speed vehicle bus. This means that the information can be typically accessed through the OBDII DLC. The ABS controller/modulator is the heart of any ABS or ESC system. The modulator gets the brake pressure from the master cylinder. Inside are the valves and solenoids that control the pressures to the wheel. During normal operation, the pressure from the master cylinder goes through the HCU unaltered.
ABS/ESC: Hydraulic Control Unit/Modulator Diagnostics
Under normal braking conditions, the master cylinder supplies fluid to the HCU and routes the pressure to the calipers. The solenoids are not energized allowing fluid to pass directly from the master cylinder to the caliper. The top solenoid is an isolation valve that isolates the HCU from the master cylinder during stability control interventions;
Tool Tip: Maximizing Tools: Diagnosing ABS/ESC Hydraulic Control Units
Brake & Front End Editor Andrew Markel finds the root cause of a brake pull using Innovative Products of America’s Brake System Analyzer.
Tech Tip: GMs, Hummers and Saabs May Experience Intermittent MIL with DTC P2138 and Reduced Power
Some customers may comment on an intermittent malfunction indicator lamp (MIL) being illuminated with a message or an indicator that displays Reduced Engine Power.
Airtex Vehicle Electronics Introduces ‘Better Than OE’ ABS Sensors
Engineers at Airtex Vehicle Electronics say they have addressed the leading cause of ABS wheel-speed sensor failure – environmental damage – with a new line of better-than-OE sensors that feature heavy-duty insulation and other enhancements. These sensors are available for virtually any popular late-model domestic or foreign nameplate application, according to Airtex.
Tech Tip: Intermittent ABS Operation Caused by Cracked Sensor Ring
Rust can develop between the axle and the ABS speed sensor ring. The rust acts like a wedge and causes the ring to crack, creating a false or erratic signal that results in intermittent ABS operation.
Delphi Adds Two ABS Sensors to its Engine Management Portfolio
Delphi is continuing to expand its all-makes ABS program with the addition of two new ABS sensors covering Mazda applications.
