ABS Light Stays On in Geely Atlas? Wheel Speed Sensor Faults Explained

What does the ABS light mean?

When the ABS warning light stays on continuously in your Geely Atlas, the system has detected a fault and has disabled itself for safety. The most common culprit is a wheel speed sensor—one of the four sensors mounted at each wheel hub that monitor how fast each wheel is turning.

Likely causes and what to check first

• Contaminated or damaged sensor: Road grime, brake dust, or metal shavings can block the sensor's magnetic field. Inspect the sensor tip for debris and clean it with brake cleaner.
• Damaged wiring or connector: Corrosion, frayed wires, or a loose plug at the wheel well can interrupt the signal. Check the harness where it rubs against suspension parts.
• Faulty sensor ring (tone ring): A cracked or missing tooth on the reluctor ring will cause erratic readings. Rotate the wheel and inspect the notched ring for damage.
• Sensor failure: If cleaning and wiring checks don't help, the sensor itself may be internally shorted or open. Use a multimeter to measure resistance—typically 1–2 kΩ.

Is it safe to keep driving?

Yes, you can still drive with the ABS light on, but keep in mind that the anti-lock braking system will not activate in an emergency stop. The regular brakes will still work, but wheels can lock up on slippery surfaces. We recommend having the fault diagnosed and repaired as soon as possible—especially if you drive in wet or icy conditions.
