Chery Tiggo 3 ABS Light Stays On: Wheel Speed Sensor & What to Check

Why Your Chery Tiggo 3 ABS Light Is On

When the ABS light stays on continuously, the ABS module has detected a fault and disabled the anti-lock braking system. On the Chery Tiggo 3, the most common culprit is a wheel speed sensor — especially at the front wheels. These sensors read the speed of each wheel and send that data to the ABS module. If one sensor fails or sends an erratic signal, the module sets a code and turns on the light. Other likely causes include damaged wiring or connectors near the wheels, a cracked or dirty ABS tone ring (the toothed ring on the hub), a blown ABS fuse, or a faulty ABS module. Before replacing parts, a mechanic will scan for trouble codes to pinpoint which wheel is affected.

What to Check First (and in What Order)

• Scan for ABS codes: This tells you which wheel sensor is reporting a problem. Don't guess — a $50 scan can save you hours.
• Inspect the sensor and wiring: Look for chafed wires, corroded connectors, or a sensor covered in metal debris. Clean or replace as needed.
• Test sensor resistance and output: A multimeter can check resistance; a scope or live data can show if the signal drops out while spinning the wheel.
• Check the tone ring: A cracked, rusted, or missing teeth on the ring will cause false readings. Replace the ring or axle if damaged.
• Verify fuses and module power: If all sensors check out, test the ABS fuse, relay, and module connectors.

Is It Safe to Keep Driving?

Yes, you can usually drive with the ABS light on — your normal brakes still work. But remember: the anti-lock function is disabled. That means in a panic stop or on slippery roads, your wheels can lock up and you may lose steering control. It's not an emergency, but don't ignore it. Avoid harsh braking, and get it diagnosed within a week or two. If the brake warning light (the one with an exclamation mark) also comes on, or the pedal feels strange, stop driving and have it towed. A simple wheel speed sensor replacement is often inexpensive and restores your ABS quickly.
