Power Steering Control Module Calibration

Warning: An inaccurate or not centred steering angle sensor could limit the operation of the electric power steering (EPS) and result in personal injury.

Centring 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:

Note: It is necessary to perform the steering angle sensor centering BEFORE the software endstop learning.

Steering Angle Sensor Centreing

For electronic power steering equipped vehicles WITH electronic stability control program and EXTERNAL Steering Angle Sensor, refer toSteering Angle Sensor Centreing .

The centring procedure of the internal steering angle sensor (w/o electronic stability program) can be completed with the following steps:

Conditions: Front axle measured and set, engine running, 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 Centring procedure.
3. Steer from the centre position slowly 90° to the left.
4. Steer slowly back to the centre position and then slowly 90° to the right.
5. Steer slowly back to the centre position.
6. Perform the steering movements again.
7. Centring 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. Using a scan tool, perform the Configuration/Reset Functions, Power Steering Softstops Learn procedure and follow the on-screen instructions.
3. Software endstop learning procedure is completed.
