Geely Coolray ABS Light On? Diagnosing a Faulty Wheel Speed Sensor

Why Is the ABS Light Staying On?

If your Geely Coolray's ABS warning light stays on continuously, the most common culprit is a faulty wheel speed sensor. This sensor tells the ABS control module how fast each wheel is turning. When it fails or reads incorrectly, the system disables itself and lights the dashboard warning. On the Coolray, I often see the front sensors get contaminated with brake dust, road grime, or metallic debris, which disrupts the magnetic signal and triggers the light.

Which Sensors and Parts to Check First

Start by having the ABS codes read with a diagnostic scanner. That will tell you exactly which wheel is causing the problem. The top things to inspect are:

• Front wheel speed sensors – these are most exposed to dirt, water, and heat from the brakes.
• Sensor wiring and connectors – check for chafing, corrosion, or damage near the suspension and brake lines.
• Reluctor rings / tone rings – on some Coolray models, a cracked or rusted ring can disturb the sensor signal.

Before replacing any sensor, clean the sensor tip and the mounting hole with brake cleaner, and verify the air gap. Sometimes a simple cleaning is all it takes, but if the sensor resistance is out of spec, replacement is the fix.

Is It Safe to Keep Driving?

Yes, you can still drive the Coolray, but your ABS and electronic stability control (ESC) will be disabled. Your normal hydraulic brakes still work, so you won't lose stopping power in normal conditions. However, on slippery roads or during an emergency stop, the wheels could lock up. Drive cautiously to a repair shop, avoid hard braking, and keep a longer following distance until the wheel speed sensor issue is resolved.
