This procedure addresses a vehicle configuration that uses Electric Power Steering (EPS) and does not require power steering fluid service.
Warnings
ℹ️The 2016-2024 Hyundai Tucson with 2.5L I4 engine uses Electric Power Steering (EPS) which does not use hydraulic fluid. This vehicle does not require power steering fluid service.
⚠If you are experiencing steering issues, diagnose the EPS system using a diagnostic scanner rather than attempting fluid service.
Tools required
OBD-II scanner
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
- 1Verify EPS SystemOpen 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.
- 2Check for MisdiagnosisIf 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.
- 3Inspect 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.
- 4Scan for Diagnostic CodesIf 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
