ABS Light On? What Your Changan CS55 Plus Is Trying to Tell You

What a steady ABS light really means

On your Changan CS55 Plus, an ABS light that stays on continuously is the ABS module telling you it has set a fault and disabled anti-lock braking. Your normal brakes should still work, but the system won’t pulse the brakes during hard stops or slippery conditions. The most common culprit is a wheel speed sensor or its circuit — but don’t guess; the ABS module usually stores a code that identifies which wheel is affected.

What to check first

Start with a proper scan of the ABS module, not just a generic engine-code reader. Once you know the affected wheel, inspect these items in order:

• Wheel speed sensor and connector: look for a damaged sensor, corroded pins, or a loose plug at that wheel.
• Sensor wiring harness: check for chafing, stretched wires, or moisture near the wheel arch and suspension.
• Tone ring/reluctor ring: cracked, rusted, or missing teeth can make the sensor signal drop out.
• Wheel bearing play and sensor gap: a worn bearing or incorrect air gap can trigger the same code.
• ABS module/pump: less common, but possible if wiring and sensors test fine.

Clean the sensor mounting surface, clear the code, and test-drive — but only replace a sensor after confirming the signal is actually lost. Throwing parts at it gets expensive fast.

Is it safe to keep driving?

If only the ABS light is on and the brakes feel normal, you can usually drive carefully to a shop — but remember you don’t have anti-lock braking, so leave extra distance and avoid rain, snow, or gravel. If the red brake warning light is also on, the pedal feels strange, or the car pulls while braking, stop driving and get it checked immediately. For a CS55 Plus, a steady ABS light is rarely an emergency, but it’s not a warning to ignore.
