The ESP, BAS, and ABS indicator lights of my vehicle remain on and I experience inappropriate speed at the appropriate gear. What could be wrong?
It’s likely that the ESP of your vehicle is faulty. Hence, its indicator light remaining on. The ESP (Electronic Stability Programme) or the ESC (Electronic Stability Control) uses highly technologically developed stream of sensors connected from the vehicle’s steering line to the wheels. It also combines with the BAS (Brake Assist System) and the ABS (Antilock Brake System) of the vehicle.
The ESP enhances directional and stability of the vehicle under various driving conditions. It corrects for oversteering and understeering the vehicle by signaling the BAS and the ABS to apply the brakes of the appropriate wheels. It may also reduce engine power to help the vehicle maintain the desired path.
Using the sensors in the vehicle, the ESP is able to determine the path that the driver intends to steer the vehicle and compares it to the actual path of the vehicle. When the actual path does not match the intended path, the ESP signals the BAS and the ABS to apply the brakes of the appropriate wheels in order to assist in counteracting the condition of oversteer or understeer. Oversteer is when the vehicle is turning more than appropriate for the steering wheel position while understeer is when the vehicle is turning less than appropriate for the steering wheel position.
A malfunctioning ESP/BAS/ABS will have the indicators lights on the instrument panel of the vehicle on and some form of hold onto the wheels of the vehicle from speeding according to the appropriate gear will be experienced. It is best you visit a professional auto workshop so they can diagnose the problem and fix it for you right away.
Please note that the ESP or ESC cannot prevent the natural laws of physics from acting on the vehicle nor can it increase the traction afforded by prevailing road conditions. The ESP or ESC cannot prevent accidents including those resulting from excessive speed in turns and or driving on very slippery surfaces. Only a safe, skillful and an attentive driver can prevent accidents. The capabilities of an ESP or ESC equipped vehicle must not be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.
