Geely Cityray ABS Light Stays On? Wheel Speed Sensor Troubleshooting Guide

Why Is the ABS Light on Continuously?

When the ABS warning light stays on after you start your Geely Cityray, the system's self-check has detected a problem. In most cases, the culprit is a dirty, damaged, or failed wheel speed sensor. These sensors are mounted at each wheel and send rotational speed data to the ABS control unit. If one sensor drops out or sends erratic values, the ABS module disables the entire anti-lock system and lights up the warning lamp.

What to Check First: The Wheel Speed Sensors

Begin by checking the sensor connectors and wiring at each wheel. Look for corrosion, broken wires, or physical damage from road debris. The front sensors are more exposed and fail more often than the rears. If the wiring is intact, test the sensors with a multimeter — a typical sensor should read between 0.5 and 1.5 volts when the wheel is spun manually. Compare readings across all four sensors. A zero or wildly different reading points to a faulty sensor. Also inspect the toothed tone ring for missing or cracked teeth, as these can trigger the same warning.

Other causes include a blown ABS fuse, a failing ABS pump motor, or a communication fault with the ECU — but the wheel speed sensor is the statistically most likely culprit. For an exact diagnosis, a generic OBD-II scanner with ABS read capability or a dealer-level diagnostic tool will tell you which wheel is at fault directly.

Is It Safe to Keep Driving?

Yes, you can generally keep driving, but with an important caveat: your standard hydraulic brakes will still work — you won't lose normal braking power. What you will lose is the anti-lock function, so under hard braking or on low-grip surfaces, the wheels can lock up and you may skid. Drive defensively, leave extra following distance, and avoid heavy braking. Have the sensor replaced as soon as practical, since a continuous ABS light will also typically disable traction control and stability control — meaning your Cityray's electronic safety net is gone.
