What Causes the Anti-Skid Fault Light to Illuminate in Mazda CX-4?
2 Answers
The anti-skid fault light may illuminate due to normal operation, ABS pump failure, and other reasons. Specific causes and solutions are as follows: Specific reasons for the anti-skid fault light illuminating: When the road surface is slippery, the ABS system operates normally, and the anti-skid light illuminating is a normal phenomenon; ABS pump failure can also cause the anti-skid light to illuminate; a fault in the vehicle's computer system leading to incorrect signal transmission may cause the anti-skid light to illuminate; loose or faulty sensor connections can trigger the anti-skid light; related fuse burnout or circuit short-circuit may also cause the anti-skid light to illuminate. Solutions for the anti-skid fault light illuminating: Check if the car sensor connections are loose and secure them if necessary; inspect all circuits and fuses for short-circuits and repair them promptly; update relevant software; replace the ABS pump.
A few days ago, my Mazda CX-4 also had the anti-skid warning light come on, which was really worrying. This light is the Electronic Stability Control warning light, and common causes include issues with the wheel speed sensor, which might be clogged with dirt or malfunctioning. Or uneven tire pressure or severe wear leading to misjudgment. It could also be loose wiring or a blown fuse, damaged by rough roads. Once after rain, the light came on, and I suspected moisture caused a short circuit. When the light comes on, you should stop and restart the car to see if it goes away. If it persists, go to a 4S shop for a full check as soon as possible, because it's related to anti-skid safety during turns and shouldn't be neglected for long. Regularly cleaning the wheel hubs to reduce debris accumulation can help prevent it.
