Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during electrical work.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top off with the recommended fluid (typically ATF or specific power steering fluid).
Start the engine and turn the steering wheel from lock to lock to purge air.

3. Inspect Power Steering Pump

Locate the power steering pump.
Check for leaks and listen for unusual noises while the engine is running.
If the pump is faulty, remove the drive belt and the pump, and replace it with a new unit, ensuring proper torque specifications for mounting bolts.

4. Replace Faulty Components

If error codes indicate issues with the electronic steering control module, locate and replace the module as per the manufacturer’s guidelines.
Ensure all connections are secure and free from corrosion.

5. Wheel Alignment Check

Take the vehicle to a professional alignment shop to have the alignment checked and adjusted, if necessary.
Inspect suspension components like tie rods and ball joints for wear and replace if needed.
