Yaw Rate Sensor, Front

Before replacing the Yaw Rate Sensor you need to check its condition and make sure no foreign objects clog the space between it and the body. Also verify that the sensor points in the right direction. To access the yaw rate sensor start by removing the console box sub-assembly and disconnecting its cable before removing the two bolts securing it. To install the yaw rate sensor properly, join its connector and tighten the two mounting bolts at 14 Nm (143 kgf-cm, 10 ft-lbf). Hook back the console box sub-assembly and calibrate the yaw rate sensor zero point. During testing and inspection check the VSC sensor output at the end.

The procedure for yaw rate sensor servicing and repairs includes disconnecting the negative battery cable and waiting 90 seconds to stop the activation of Air Bags and seat belt pretensioners before starting work. The first step requires removing the rear console box assembly after disconnecting the yaw rate sensor connector followed by unfastening the two bolts that hold the sensor in place. When installing the yaw rate sensor users must check it remains undamaged during placement and avoid contamination of the sensor bracket area by foreign objects between the yaw rate sensor bracket and vehicle body. Screw the yaw rate sensor into position with the two bolts while tightening them to 14 N.m (143 kgf.cm, 10 ft.lbf) before reattaching its connector. Refasten the rear console box assembly while connecting the negative battery cable. First initialize systems if necessary and finish by calibrating the yaw rate sensor zero point. The VSC sensor signal needs to be checked after completing all other steps.

Service and repair of the Yaw Rate Sensor requires users to disconnect the battery cable and wait for a minimum of 90 seconds before proceeding to prevent Air Bag and seat belt pretensioner activation. The first step requires removal of the rear console box assembly through retracting the rear console box assembly. Start by disconnecting the connector from the yaw rate sensor while also unbolting its securing bolts which number two in total. The installation process requires checking that the yaw rate sensor remains free from damage and that no foreign matter is present in the area between the bracket and body as you verify correct sensor orientation. Secure the yaw rate sensor into position with the 2 bolts that need 14 N.m (143 kgf.cm, 10 ft.lbf) torque level before reattaching the yaw rate sensor connector. Put back the rear console box assembly before connecting the negative battery cable. Complete the process by calibrating the yaw rate sensor zero point then verify VSC sensor signals.

Service professionals must start Yaw Rate Sensor repairs by verifying that only undamaged sensors get used alongside a proper orientation of the sensor and by blocking foreign objects between the yaw rate sensor bracket and body before beginning work. The service starts with removing the negative battery terminal cable before dismantling the console upper rear panel sub-assembly and console box assembly. You must disconnect the connector of the yaw rate sensor followed by removing two bolts which secure the sensor itself. During installation fasten the yaw rate sensor to its position using two bolts which must be torqued up to 14 N.m (143 kgf.cm, 10 ft.lbf) while reconnecting the yaw rate sensor connector. Install the console box assembly together with the console upper rear panel sub-assembly before reattaching the cable to the negative battery terminal. Zero-point adjustment of the yaw rate sensor must be performed before inspecting ABS and VSC warning lights and noting that system initialization might be necessary after connecting the battery.

The servicing procedure for VSC under Yaw Rate and Deceleration Sensor demands first disconnecting the cable from the negative terminal of the vehicle battery. The service for bench seat types requires separation of the front seat inner belt assemblies(LH and RH), front seat headrest assembly, and front seat assembly and seat track cover. Every cab requires the removal of front door scuff plates in addition to the cowl side trim boards. Start the sensor bracket removal process by elevating the floor carpet then separating the wire harness clamp and lastly unbolting and removing the bracket. The process begins with disconnecting the yaw rate sensor connector and afterward removing two bolts securing the yaw rate sensor. Attach the yaw rate sensor by bolt screws while keeping it at the desired angle before connecting its connector. Put the bracket sensor into position with the bolt before installing the clamp for the wire harness. All cab types require the installation of cowl side trim boards followed by front door scuff plates before the crew or owner cab installation of the front floor footrest and front seat assembly. Secure the cable to the negative battery terminal by tightening it to 3.9 N.m (40 kgf.cm, 35 in.lbf). The last step includes running a yaw rate sensor zero point calibration while also verifying the VSC sensor signal. The yaw rate sensor requires torque of 12.5 N.m along with 12.5 N.m for the sensor bracket.

The first step to remove the Yaw Rate Sensor with VSC is disconnecting the negative battery cable. The bench seat type requires removal of front seat inner belt assembly LH followed by front seat inner belt assembly RH and subsequent front seat headrest assembly as well as the front seat assembly. The process starts by taking out the seat track cover followed by the removal of the front seat assembly for separate seat types. Begin by taking out the front floor footrest yet follow with the removal of front door scuff plates that apply to all Regular Cab, Access Cab and Double Cab models. Nobody can operate on Double Cab, Access Cab and Regular Cab vehicles until they remove the cowl side trim boards. Proceed to the floor carpet and raise it to reach the sensor bracket before removing the wire harness clamp and the bolt and bracket. The installation process ends with disconnecting the connector of the yaw rate sensor followed by removing the 2 bolts that secure the yaw rate sensor.

Do not use any dropped or damaged yaw rate sensors.

Disconnect the yaw rate sensor connector and remove the two bolts securing the yaw rate sensor.

Begin by removing the console box sub-assembly rear.

First, disconnect the cable from the negative battery terminal, noting that some systems may require initialization after reconnection.

Remove the front seat assembly (both bench seat and separate seat types), front floor footrest, front door scuff plate LH, and cowl side trim board LH.

Connect the cable to the negative battery terminal with a torque of 3.9 Nm (40 kgf-cm, 35 in-lbf).

Install the seat track cover.

Reinstall the cowl side trim boards and front door scuff plates for all cab types, then the front floor footrest.
