What Causes the Traction Control Fault Light to Illuminate?
1 Answers
Car traction control fault light is on due to: 1. Fuel system malfunction: causing reduced fuel injection, low fuel pressure, or impurities in gasoline. 2. Inaccurate air measurement: resulting in discrepancies between detected and actual air intake. 3. Inaccurate closed-loop feedback signals: such as faulty oxygen sensors. The traction control indicator displays the working status of the vehicle's TCS (Traction Control System). When illuminated, it indicates the TCS has been deactivated. The vehicle's traction control system prevents wheel slippage by reducing throttle opening, adjusting ignition timing, forcing transmission downshifts, and coordinating with ABS to regulate tire rotation speed.
