Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the manufacturer-recommended fluid.
If the fluid is dirty or contaminated, drain the old fluid using a turkey baster or similar tool.
Refill with fresh power steering fluid to the appropriate level.

3. Check and Replace the Power Steering Pump (if necessary)

If diagnostics indicate a malfunctioning pump, proceed to replace it.
Disconnect the hoses from the power steering pump using a socket set.
Remove the mounting bolts securing the pump to the engine.
Install the new pump by reversing the removal steps, ensuring proper torque specifications are followed (typically around 25-30 Nm).
Reconnect the hoses and ensure there are no leaks.

4. Repair or Replace Electrical Connections

Inspect the wiring harness and connectors associated with the EPS system for corrosion or damage.
Clean any corroded connections with electrical cleaner.
If damaged, replace the wiring harness and connectors as necessary.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the EPS light is still illuminated.
Perform a test drive to ensure power steering assist is functioning correctly.
