Resetting a car's electronic power steering system usually requires professional equipment and technical support. It is best to contact an authorised service centre first. However, if you need to attempt it yourself, you can follow these general steps: First, ensure the vehicle is turned off and stationary. Open the bonnet to locate the OBD2 diagnostic port (typically located under the steering wheel or in the engine compartment). Connect a compatible diagnostic tool, then select the "Electronic Power Steering" module and perform the reset procedure. Some models may support a simplified reset method, such as pressing and holding the EPS button near the steering wheel for 5 seconds (with the ignition switch in the ON position but the engine not running). Upon completion, turn off the power, wait 30 seconds, then restart the engine for testing. For instance, certain models require calibration at specific steering wheel angles. If the power steering warning light remains illuminated on the dashboard, this typically indicates mechanical or electrical faults (such as torque sensor malfunctions or blown fuses), necessitating professional servicing. As the electronic power steering system is critical for driving safety, DIY solutions should only be considered as temporary emergency measures. Long-term reliability requires proper diagnosis and maintenance by certified technicians.
