When the ABS light is on and the car cannot start, there may be the following three reasons: The ABS light indicates that the ABS anti-lock braking system of the car is malfunctioning. When the ABS light is on, some vehicles' safety systems will automatically lock the ignition system, preventing the car from starting. 1. There is an open circuit in the connection line between the wheel speed sensor and the control unit of the ABS safety system. 2. A large amount of dust or impurities in the gap between the wheel speed sensor and the toothed ring or at the sensor installation position affects speed monitoring. 3. After a vehicle collision, the wheel bearing spacing becomes wider, causing transmission issues.
