Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, power steering fluid, clean shop towels.
Disconnect the negative battery terminal to ensure safety during the repair.

2. Check and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid condition; if it is dark or contaminated, drain the old fluid using a siphon.
Refill the reservoir with the recommended power steering fluid (Tesla uses a specific fluid type).
Replace the reservoir cap securely.

3. Inspect and Replace Power Steering Components

Power Steering Pump:
- If fluid levels are fine but issues persist, check the power steering pump.
- Remove the pump drive belt using a socket set.
- Detach the pump from the mounting bracket, noting the orientation of any hoses.
- Install the new pump, ensuring all connections are tight and reconnect the drive belt to manufacturer specifications.
Power Steering Motor:
- If the motor is suspected to be faulty, disconnect the electrical connector from the motor.
- Remove the mounting bolts and carefully extract the motor from the assembly.
- Install the new motor, ensuring proper alignment and torque specifications for the mounting bolts.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and turn the steering wheel from lock to lock to circulate the fluid and bleed any air out of the system.
Check for any leaks around the replaced components.
