Angle Sensor

A proper replacement of the steering angle sensor begins with battery terminal disconnection along with proper safety steps. Start by placing front wheels in straight position before removing horn button assembly together with steering wheel assembly, steering column cover and spiral cable sub-assembly. You must carefully detach the 4 claw fittings which will allow you to take off the steering sensor from the spiral cable before securely placing the new steering sensor onto the spiral cable so that the claw remains undamaged. To finish the installation procedure you must first align the center front wheel before putting back the spiral cable sub-assembly and centering the spiral cable. You need to reinstall the steering wheel assembly before performing inspections of the steering wheel center point then checking the horn button assembly as well as the SRS warning light. Conclude VSC system calibration while inspecting the warning lights for both ABS and VSC.

The service and repair process of the steering angle sensor requires specific safety measures to follow. After disconnecting the cable from the negative terminal users need to wait 90 seconds before moving on to prevent the Air Bag and seat belt pretensioners from activating. Proceed with wheel alignment before eliminating the steering pad assembly as well as the steering wheel assembly and steering column cover and spiral cable sub-assembly and steering sensor by loosening the 4 claw fittings. Install the steering sensor onto the spiral cable by placing it properly where the claw fits without damaging the components. Set the front wheel to central alignment and position the spiral cable sub-assembly before reinstating the steering column cover along with the steering wheel assembly and steering pad assembly. The negative battery terminal cable should be reconnected before examining the steering pad assembly. A systematic initialization procedure must start after joining the battery cable because select systems need this process. Perform a check of the SRS warning light and then complete VSC system calibration as well as inspect both ABS and VSC warning lights.

The process of removing the Steering Angle Sensor requires the front wheel alignment in straight position with a negative battery terminal cable disconnect to disable Autoaway/Return feature by adjusting customize parameters before recording current settings for later reinstallation. Once the engine switch (IG) is activated to extend the steering column fully, users should lower it using the tilt and telescopic switch then turn off the engine before letting the cable disconnect from the negative terminal and wait at least 90 seconds to disable the SRS system. Remove the components from the steering wheel assembly by starting with LOWER NO. 2 STEERING WHEEL COVER and ending with UPPER STEERING COLUMN COVER. The SPIRAL CABLE SUB-ASSEMBLY must be removed first before the operator can detach six claws which permit removal of the STEERING ANGLE SENSOR.

The first step to uninstall the Steering Angle Sensor consists of studying caution advice related to Air Bag and seat belt systems. The process to disconnect the negative battery cable must exceed 90 seconds to stop Air Bag and seat belt pretensioner activation. First lock the front wheels straight ahead position before beginning the process of steering pad assembly removal followed by the steering wheel assembly. Proceed by removing the steering column cover after which you must detach the spiral cable sub-assembly. Unfasten the six claws which will let you remove the Steering Angle Sensor from the spiral cable.

A proper servicing start for the Steering Angle Sensor requires detailed reading of all precautions. You should disconnect the negative battery cable before waiting for 90 seconds to avoid Air Bag activation. Before you restore power to the vehicle keep both the front tires and steering wheel in a direct alignment with the front wheels facing forward. The service process requires removal of the steering wheel cover lower pieces No. 2 and No. 3 together with the steering pad and steering wheel assembly before proceeding with removal of the steering lower column cover and steering column cover. The engineer should start by uninstalling the spiral cable sub-assembly which contains the steering angle sensor and then proceeds to disconnect the steering angle sensor by opening its claws. To mount the signal sensor fit its locating pins then engage the claws before placing the sensor onto the spiral cable. Position the spiral cable sub-assembly with steering angle sensor before installing both steering column cover and steering lower column cover. The spiral cable needs to be adjusted before installing the steering wheel assembly and evaluating the steering wheel center point before applying the steering pad. The last task involves reinstalling the No. 2 and No. 3 steering wheel cover lowers followed by connecting the cable to the negative battery terminal then checking the steering pad and SRS warning light.

Reinstall the steering column cover and steering wheel assembly.

Check the SRS warning light.

Operate the tilt and telescopic switch to fully extend and lower the steering column.

Remove the steering pad assembly, steering wheel assembly, steering column cover, and spiral cable sub-assembly.

After installation, inspect the steering wheel center point and connect the cable to the negative battery terminal.

Remove the No. 3 Steering Wheel Cover.

Remove the steering pad assembly, steering wheel assembly, steering column cover, spiral cable sub-assembly, and detach the 6 claws.
