Preparation

Verify the vehicle is equipped with Electric Power Steering by confirming there is no power steering fluid reservoir under the hood
If steering concerns exist, ensure the battery is fully charged as EPS relies on electrical power

Procedure

1
Verify EPS System
Open the hood and inspect the engine bay. Confirm there is no power steering fluid reservoir present. The 2.5L I4 Tucson uses an electric power steering motor mounted on the steering column, not a hydraulic pump and fluid system.
2
Check for Misdiagnosis
If you were directed to perform this service due to steering concerns, verify the actual issue. Electric power steering problems typically manifest as heavy steering at low speeds, lack of assist, or warning lights on the dashboard. These require electrical diagnosis, not fluid service.
3
Inspect EPS Components (If Applicable)
If steering issues are present, visually inspect the EPS motor on the steering column for damage, loose connectors, or corrosion. Check the instrument cluster for any EPS warning lights or messages.
4
Scan for Diagnostic Codes
If steering concerns exist, connect an OBD-II scanner and check for EPS-related diagnostic trouble codes (DTCs). Common codes include C1513 (EPS Control Module Malfunction) or C1514 (EPS Motor Circuit).

Reassembly

No disassembly or reassembly required for this verification procedure

Verification

Confirm the vehicle has Electric Power Steering by the absence of any hydraulic components
If steering issues were present, address them through EPS electrical system diagnosis rather than fluid service
