Solution

1. Preparation

Gather tools and parts required for the repair. Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Refill Power Steering Fluid

Tools Required: Fluid pump, funnel, clean cloth
Check the power steering fluid reservoir for low levels. If low, refill with the manufacturer-recommended fluid.
Inspect for leaks around hoses and connections, tightening any loose fittings.
Clean any spilled fluid to prevent slipping hazards.

3. Replace Steering Components (if necessary)

Tools Required: Socket set, torque wrench, steering wheel puller (if needed)
If damaged components are found during inspection, replace them:
1. Remove the wheel (if required) by loosening the center nut and using a steering wheel puller.
2. Disconnect the electrical connectors from the EPS motor and remove the mounting bolts.
3. Replace the affected part (e.g., steering rack, tie rod) with the new component.
4. Reassemble in reverse order, ensuring all bolts are torqued to manufacturer specifications.

4. Calibrate Steering Angle Sensor

Tools Required: Tesla diagnostic tool or software
Reconnect the battery and power on the vehicle.
Use Tesla’s service tool to initiate the steering angle sensor calibration procedure.
Follow on-screen prompts to complete the calibration.
