Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's battery to ensure safety.
Allow the vehicle to sit for at least 10 minutes to dissipate electrical charges.

2. Inspect and Clean Connections

Remove any covers or panels obstructing access to the power steering motor.
Visually inspect all electrical connectors for damage, corrosion, or looseness.
Clean connectors with electrical contact cleaner and reconnect securely.

3. Test and Replace Power Steering Motor (if necessary)

Tools Required: Torque wrench, socket set, multimeter.
Disconnect the power steering motor connector.
Use a multimeter to check voltage at the connector while turning the steering wheel.
If voltage is within spec but the motor is unresponsive, proceed to replace the motor:
1. Remove the bolts securing the power steering motor using a socket set.
2. Carefully detach the motor from the steering column.
3. Install the new power steering motor by reversing the removal steps.
4. Torque bolts to manufacturer's specifications (refer to service manual for specific torque values).

4. Reassemble and Reconnect Battery

Reinstall any covers or panels removed during the process.
Reconnect the vehicle's battery terminals.

5. Clear Error Codes

Use an OBD-II scanner to clear any stored error codes related to the power steering system.
