What is the reason for the ABS and anti-skid lights being on in the Cavalier?

The reasons for the ABS and anti-skid lights being on in the Cavalier are: 1. Short circuit in the wiring; 2. Loose or faulty sensor connectors; 3. Issues with the ABS system software; 4. ABS computer malfunction. The Cavalier is a compact sedan under SAIC-GM-Chevrolet, with body dimensions of: length 4474mm, width 1730mm, height 1471mm, and a wheelbase of 2600mm. The Cavalier is equipped with a 1.0T dual-injection turbocharged three-cylinder engine, paired with a 6-speed automatic manual transmission. The front suspension adopts a MacPherson independent suspension, while the rear suspension uses a torsion beam non-independent suspension.
As someone who has been driving for over a decade, when both the ABS and traction control lights come on, I suspect it's a common issue with the Cavalier. The wheel speed sensor might be faulty—dust buildup or a broken sensor can affect wheel speed detection. ABS module failure is also common; this component controls the anti-lock braking system, and if it ages or has software errors, it will trigger an alert. Another possibility is worn wheel bearings, which can cause signal misreading. Abnormal tire wear or uneven road surfaces can also interfere with the system's normal judgment. If you don't clean the dust around the wheel rims regularly, the sensors are prone to malfunction. When you notice the lights on, you should stop and check. Continuing to drive may increase braking distance and risk, so head to the repair shop for a computer scan immediately. During regular maintenance, have the technician inspect the wheel speed sensors to prevent issues—don't ignore this small warning signal.
