Steering Angle Sensor Centering and Software Endstop Learning

Centering of the steering angle sensor and software endstop learning might be required after certain service procedures are performed. Some of these procedures are as follows:

• Steering angle sensor replacement
• Steering gear replacement
• Power steering assist motor replacement
• Steering column replacement
• Steering linkage inner tie rod replacement
• Steering linkage outer tie rod replacement

Internal Steering Angle Sensor Centering 

The centering procedure of the internal steering angle sensor can be completed with the following steps:

Conditions: Front axle measured and set, engine off, vehicle speed 0 km/h (0 MPH), internal steering angle sensor is activated.

1. Using the steering wheel, align the front wheels in the center forward position.
2. Using a scan tool, perform the Configuration/Reset Functions, Steering Wheel Angle Sensor Centering procedure.
3. Steer from the center position slowly 90° to the left.
4. Steer slowly back to the center position and then slowly 90° to the right.
5. Steer slowly back to the center position.
6. Perform the steering movements again.
7. Centering procedure is completed.

Software Endstop Learning 

The software endstop learning procedure can be completed with the following steps:

Conditions: Front axle measured and set, vehicle speed 0 km/h (0 MPH), internal steering angle sensor is calibrated or external steering angle sensor sends a valid CAN signal.

1. Using a scan tool, perform the Configuration/Reset Functions, Power Steering Softstops Reset procedure and follow the on-screen instructions.
2. Rotate the steering wheel to the left until the endstop is reached and hold position for 2 seconds.
3. Rotate the steering wheel to the right until the endstop is reached and hold position for 2 seconds.
4. Return the steering wheel to the center position.
5. Software endstop learning procedure is completed.
