Toyota Hilux Electronic Power Steering EPS Issues – How to Reset?

Electronic Power Steering EPS issues in newer Toyota Hilux models can sometimes cause stiff steering, loss of power assist, o r warning lights on the dashboard. Some common EPS-related problems include:

Stiff Steering o r Loss of Power Assist: This can happen if the EPS motor o r electronic control unit ECU is malfunctioning, leading to a sudden loss of power steering assistance. It may feel like steering becomes very heavy, especially at low speeds o r when parking.

Warning Lights: If the EPS system detects a fault, the steering warning light may appear on the dashboard. This could indicate a problem with the EPS motor, sensors, o r wiring.

Troubleshooting and Resetting EPS:

Check the EPS Fuse: If the steering becomes stiff o r unresponsive, a blown fuse could be the culprit. Check the fuse box and replace any blown EPS fuses.

Inspect Wiring and Connections: Ensure that the wiring to the EPS motor and ECU is secure and free of corrosion o r damage. Loose o r damaged wiring can cause intermittent power steering issues.

Reset the EPS System: Sometimes, simply resetting the EPS system can solve the issue. This can be done by disconnecting the vehicle’s battery for about 15-30 minutes. This allows the ECU to reset, clearing any minor faults o r glitches that could be causing the issue.

Sensor Calibration: If the problem persists after resetting, the EPS system’s sensors might need recalibration. This is usually done through a diagnostic tool at a dealership o r trusted mechanic.

Visit a Professional: If troubleshooting steps like checking the fuse o r resetting the system don’t work, the EPS motor o r ECU might be faulty and require professional diagnosis and repair.
