What are the functions and components of the Anti-lock Brake (ABS) and Stability Assist (VSA) systems,ABS Control Module and ABS Wheel Speed Sensor on Acura TL?

The Anti Lock Brake (ABS) and Vehicle Stability Assist (VSA) systems are also built to enhance vehicle steerability, directional stability and the best possible deceleration, all under severe braking on any of the road surfaces. The ABS watches for wheel lockup during heavy braking controlling brake line pressure according to wheel rotational speed and the VSA aids in correcting over/under steering. The Traction Control System (TCS) enables vehicle control in difficult situations together with, but the Traction Control System (TCS) prevents wheel spin during acceleration on slippery roads, and so on. An electric hydraulic pump is in the engine compartment in the modulator unit with the modulator unit containing solenoid valves to modulate brake line pressure and the actuating hydraulics which are the electric hydraulic pump to the actuating hydraulics to provide pressure to the braking system. An electronic module interprets a signal produced by each of a pair of speed sensors that generate a signal proportional to wheel speed. Steering knuckle and the rear suspension knuckle mounting the front sensors and rear sensors respectively. On the modulator, the ABSNSA computer processes sensor information so that hydraulic pressure can be controlled, and that system faults are monitored. If a dashboard warning light stays illuminated, then verify the brake fluid level, secure electrical connections, and the fuses, but especially check fuses, before having a professional diagnose and repair your vehicle. Before handling electrical connections you should turn off the ignition with caution. To remove the wheel speed sensor the vehicle will need to be raised and supported securely, the ignition turned off and the sensor wiring traced and disconnected before removing the sensor from the knuckle. Following this installation is done in reverse order and all components are secure.

Acura TL ABS Wheel Speed Sensor

Acura TL ABS Wheel Speed Sensor helps maintain a steady level at each stop by using information about how fast each wheel is spinning and feeding it into the ABS computer so that lockup never gets a chance to begin. This Acura component, the ABS Wheel Speed Sensor, is located next to a toothed ring on the hub or axle, which generates voltage pulses as the teeth pass the magnetic tip. This controller then compares the signals from all corners to identify the wheel that slows down too quickly and briefly reduces hydraulic pressure so the car can control. Early TL models applied a passive ABS Wheel Speed Sensor that had an electromagnetic coil which provided an analog AC waveform signal, but later TL generations switched to an active ABS Wheel Speed Sensor that uses a magnet and a Hall Effect chip to provide an accurate and crisp digital output signal, which is much better at low speeds. Both styles aid in keeping Acura braking predictable by sharing sealed housings and plug-in wiring, but the active type has quicker response and greater immunity to electrical noise. Should an ABS Wheel Speed Sensor fail, the ABS warning light illuminates, normal braking is preserved, but anti-lock aid is lost, which is a reminder to Acura drivers that their TL is dependent on this little part to assure them of confident stops.

We provide a broad range of OEM Acura TL ABS Wheel Speed Sensor at unbeatable prices on our website. For your OEM parts, You can count on the guaranteed quality, manufacturer's warranty, outstanding customer service, and prompt delivery. We look forward to your visit.
