Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Replace Steering Angle Sensor

Locate the Steering Angle Sensor:
- Typically located on the steering column or near the steering rack.
- Remove any coverings or panels obstructing access.
Disconnect the Sensor:
- Carefully unplug the electrical connector from the steering angle sensor.
- Ensure no damage occurs to the wiring harness during disconnection.
Remove the Old Sensor:
- Use the appropriate socket to remove the mounting screws or bolts securing the sensor.
- Gently pull the sensor free from its mounting position.
Install the New Sensor:
- Position the new steering angle sensor into place.
- Secure it with the mounting screws or bolts, tightening to manufacturer specifications (usually around 10-15 Nm, check service manual).
Reconnect the Electrical Connector:
- Plug the wiring harness back into the new sensor until it clicks into place.

3. Reset the ABS System

Use the OBD-II Scanner:
- Reconnect the scanner to the vehicle’s diagnostic port.
- Clear the C1241 code and any other related codes present in the ABS system.
Perform a Calibration:
- Follow the specific procedure for steering angle sensor calibration, typically found in the service manual.
- This may involve turning the steering wheel from lock to lock while the vehicle is stationary.

4. Final Checks

Replace any panels or coverings removed during the process.
Ensure all tools are removed from the engine bay.
