1 Answers
Below are the reasons why the anti-theft indicator light suddenly starts flashing when it didn't before, along with corresponding solutions. Details are as follows: Normal Alarm Trigger: If the engine anti-theft light flashes at a regular frequency, it indicates that the vehicle's engine has entered the anti-theft mode. The engine anti-theft system is functioning normally, and the flashing anti-theft indicator light signals that the vehicle's electronic anti-theft system has been triggered. Solution: Inspect the vehicle and take appropriate measures. Fuel Issues: First, check the front and rear oxygen sensors. Early signs of damage may include the engine warning light staying illuminated on the dashboard. Modern vehicles typically have two oxygen sensors, located before and after the catalytic converter. Solution: Promptly troubleshoot the issue or replace the faulty components.
