Chery Tiggo 2 ABS Light Stays On: Wheel Speed Sensor Clues

What a constant ABS light means on your Tiggo 2

If the ABS warning light stays on after the bulb check, the ABS module has disabled the anti-lock braking function and stored a fault code. On the Chery Tiggo 2, the most common culprit is a wheel speed sensor that has failed, become dirty, or lost its signal. The system compares wheel speeds; if one sensor reads zero or jumps around, it switches ABS off and turns on the light. Your normal brakes should still work, but you lose the skid-prevention help.

Parts and checks to start with

Start with an ABS scan tool that can read live wheel-speed data. That will tell you which corner is misbehaving before you buy parts. Then inspect the likely items:

• Wheel speed sensors at each hub — look for cracked plastic, metal debris, a loose mounting bolt, or a damaged connector.
• Tone rings/reluctor rings — rust, mud, or missing teeth can make the signal unreadable.
• Wiring and connectors — chafed wires near the strut, corroded pins, or water in the plug are common on older Tiggo 2s.
• Sensor gap and hub play — a worn wheel bearing can move the sensor away from the ring and cause an intermittent or permanent fault.
• ABS fuses and battery voltage — a weak battery or blown fuse can trigger a false ABS light.

Is it safe to keep driving?

If only the ABS light is on and the red brake warning light is off, the car will usually brake normally, so a careful drive to a workshop is possible. However, ABS is disabled, so emergency stops, wet roads, gravel, or snow can become much riskier because the wheels may lock. If the brake warning light is also on, the pedal feels soft, or you hear grinding, stop driving and have it towed. A quick diagnostic now can save you from a much bigger repair later.
