What does the ASR warning light mean?
1 Answers
ASR warning light staying on indicates there may be a fault in the vehicle's traction control system. Here are the functions of ASR: 1. Its main purpose is to prevent driving wheel slippage during acceleration, especially on low-friction surfaces like rain, snow, hail or icy roads. It controls the slip ratio within a certain range during acceleration to prevent rapid wheel spin. 2. Its functions include improving traction and maintaining driving stability. On slippery surfaces, vehicles without ASR are prone to wheel spin during acceleration. 3. For rear-wheel drive vehicles, this may cause fishtailing; for front-wheel drive vehicles, it may lead to loss of steering control. With ASR, these phenomena can be prevented or significantly reduced during acceleration.
