Why do the ABS and skid control lights illuminate on the Mazda3 Axela?
1 Answers
There may be several reasons: the vehicle's skid control function is turned off; a fault in the wheel speed sensor circuit; or a malfunction in the ABS pump. The specific causes are as follows: 1. The vehicle's skid control function is turned off: If the driver accidentally disables the skid control function in the vehicle settings, it will cause the onboard computer to report an error and trigger the skid control light on the dashboard. Check whether the skid control function is turned off in the vehicle settings. 2. Fault in the wheel speed sensor circuit: When the vehicle encounters an obstacle while driving and needs to make an emergency turn to avoid it, the vehicle stability system uses the wheel speed information collected by the wheel speed sensor to adjust the vehicle's movement posture and prevent skidding and loss of control. A faulty wheel speed sensor will trigger the skid control light on the dashboard. The technician will lift the vehicle with a lift and use a multimeter to check for faults in the wheel speed sensor circuit. 3. ABS pump malfunction: A faulty ABS pump will prevent the vehicle stability system from controlling wheel rotation via the ABS during emergency turns, making it unable to adjust the vehicle's movement posture and prevent loss of control. The technician will use a specialized automotive diagnostic tool to read the ABS pump data and determine whether the ABS pump is faulty.
