BRAKE 45 INSTALLATION 1. Clean speed sensor and its mounting surface. 2. Route the cable properly. 3. Install the wiring harness connector with wheel speed sensor cable. 4. Make sure that the sensor cable connector is fully seated and locked into vehicle wiring harness connector. 5. Insert the sensor into the sensor mounting hole and tighten the bolt to the specified torque (0.8 – 1.0 Kg-M). 6. Check the air gap between the face of the wheel speed sensor and the top surface of the toner wheel. NOTE: Air gap should be 0.5 to 1.5 mm. Clear all fault codes and road test vehicle to ensure proper operation of the brake system. I. YAW RATE SENSOR WORKING PRINCIPLE A yaw rate sensor is a gyroscopic device that measures a vehicle’s angular velocity around its vertical axis. The output is usually in degrees per second or radians per second. The angle between the vehicles heading and vehicle actual movement direction is called slip angle, which is related to the yaw rate. The measurement is based on the Coriolis Effect. The Coriolis Effect is an apparent deflection of moving objects when they are viewed from a rotating reference frame. This Sensor is used to measure the physical effects of yawing, lateral and longitudinal acceleration. In order to achieve this, the Sensor features both a sensor element for yaw rate and one or two sensor elements for acceleration. LOCATION Yaw rate sensor is located on transmission tunnel in front of the gear stick\under the floor console.
