How to Deal with the EPC Light Coming On While Driving?
2 Answers
Methods to handle the EPC light coming on while driving: First, check if the brake lights of the car are still functioning. If the brake lights are working, it is necessary to go to an auto repair shop to diagnose the fault using specialized testing equipment. If the brake lights are not working, you can try checking the brake switch, bulbs, and wiring. Sometimes, the issue might simply be due to a damaged brake bulb, and replacing the bulb can resolve the problem. The EPC indicator light coming on indicates that the system has detected a fault in the engine or electronic system. The engine control unit monitors the electronic throttle system to detect faults and displays them via a small yellow light installed in the instrument cluster.
I've been driving for almost ten years and have encountered the EPC light coming on a few times. This is the warning light for electronic throttle control, and it may illuminate due to a dirty throttle body, a faulty brake switch, or sensor issues. I recommend immediately slowing down to a safe speed, avoiding sudden acceleration, and finding a safe place to pull over and turn off the engine. Wait a few minutes and restart to see if the light goes off. If it remains on, avoid driving further. Last time this happened to me, it was caused by a non-functioning brake light, so remember to check if your rear brake lights are working properly. It's best to carry a simple OBD scanner to check the trouble codes. If you don't have the tool, go straight to a repair shop for inspection. Don't underestimate this issue—it can be dangerous as severe cases may lead to sudden loss of power.
