Solution

1. Preparation

Gather tools and parts before starting the repair.
Safety warning: Disconnect the battery before working on electrical systems to prevent shocks or shorts.

2. Address Check Engine Light

Retrieve Codes: Connect the OBD-II scanner to the vehicle's diagnostic port and retrieve the stored codes.
Clear Codes: If necessary, clear the codes and perform a test drive to see if they return.
Resolve Issues: Based on the codes retrieved, address the underlying issues, which could involve replacing sensors, fixing leaks, or repairing electrical connections.

3. Inspect and Repair Steering System

Check Fluid Levels:
- Locate the power steering fluid reservoir.
- Ensure fluid is at the appropriate level; refill if necessary with OEM-spec power steering fluid.
Inspect Components:
- Lift the vehicle and visually inspect the steering components for wear or damage (tie rods, steering rack, etc.).
- Replace any damaged components with OEM parts.
Test EPS System:
- Reconnect the battery and turn the ignition on without starting the engine.
- Use the multimeter to check the voltage at the EPS motor; it should match specifications found in the service manual.
- If it’s out of range, replace the EPS motor or electronic control unit (ECU) as necessary.
