What is the reason why the failure light of Volkswagen Pu Sang EPC is not on in rainy days?

English abbreviation for electronic stability system of engine, also known as electronic throttle, is commonly used in Volkswagen. This light is on all the time, indicating that there is something wrong with the electronic system of the engine. Please check whether the brake light switch can't be turned off. When the brake light switch can't be turned off and the driver turns on the throttle again, the electronic system will think that the driver is stepping on the brake and has the throttle, which is contradictory, so that a fault occurs and the fault light will light up.

. Sometimes the light comes on when the throttle is dirty. Go to the repair shop to deal with it, clean the throttle and eliminate the fault code.
