What Causes the ESC Warning Light to Illuminate?
1 Answers
ESC warning light illumination indicates a malfunction in the vehicle's ESC system, meaning the electronic stability control system is currently inoperative. The ESC warning light may be triggered by software system alerts, sensor failures, wiring short circuits, or even false alarms. Professional diagnosis and repair using specialized fault diagnostic equipment at a 4S dealership are required. ESC Warning Light Overview: ESC stands for Electronic-Stability-Controller, which translates to the vehicle's electronic stability control system. Primary Functions of ESC: The main purpose of ESC is to enhance stability and safety during lane changes or cornering. Under normal driving conditions, the ESC system remains inactive. When the ignition is turned on, ESC activates, the warning light illuminates, and the ESC off indicator lights up for approximately 4 seconds before turning off. If the ESC warning light stays constantly illuminated while driving, it signifies an ESC malfunction, and the vehicle's electronic stability control system will not function.
