Yaw Rate Sensor

Attach the connector and clamp tightly to their position on the sensor first. Press the claw tool through the sensor bracket's opening into the sensor body then fasten it with two bolts which need 20 Nm tightening pressure. Make sure no foreign objects stick to the space between the sensor bracket and body part as you protect the sensor and ensure its secure fixing. After putting on the Left Hand Side power or manual seat assembly install the slide adjuster lock for a proper inspection. Install the track covers inside and out on each seat which handles power or manual movement. Detach the Front Seat Headrest and clip the cable to the battery minus terminal to check both Power Seat and Battery status. Before using the Manual Seat system you need to set the zero point calibration. Test and align the Yaw Rate and Acceleration Sensor and examine the SRS warning light related to the Front Seat Side Air Bag.

Begin the Yaw Rate and Acceleration Sensor installation by firmly connecting the connector along with the clamp to the sensor device. Thread the claw of the sensor bracket through the sensor until the bracket is set and fasten it in place by using two bolts with 20 Nm (204 kgf-cm, 15 ft-lbf). The installation process requires checking that no foreign objects bond to the sensor bracket-body contact surfaces yet confirming proper attachment of the sensor. The front seat assembly should be installed after which the cable must be attached to the negative battery terminal. Examine and readjust both zero points of yaw rate and acceleration sensor then check the SRS warning light.

Remove the front seat assembly for both power and manual seats.

The yaw rate sensor works in conjunction with the acceleration sensor and the vehicle stability control (VSC) system to enhance safety and performance during driving.
