Geely Geometry C ABS Light Stays On: What It Means and What to Check

Why your ABS light is staying on

On a Geely Geometry C, a continuously lit ABS warning lamp means the ABS control module has detected a fault and has disabled the anti-lock braking function. The most common culprit is a wheel speed sensor or its circuit — a dirty or damaged sensor, a corroded connector, a chafed wire, or a cracked tone ring at the hub. It can also be triggered by a weak 12V battery, low brake fluid, or an ABS module issue. Because the car uses wheel speed data for ABS and stability control, one bad signal can set the light and stay on until the fault is repaired and the code is cleared.

What to check first

• Scan for ABS codes: Use a diagnostic tool that reads ABS/ESP codes, not just engine codes. The code will usually point to the affected wheel, such as front left or rear right.
• Inspect each wheel speed sensor: Look for road debris, metal shavings, cracked sensor bodies, and damaged connectors. Clean the sensor tip and mounting area carefully.
• Check the tone ring: A rusty, cracked, or missing magnetic tone ring can cause a steady ABS light even when the sensor itself looks fine.
• Test the wiring and battery: Check for chafed harnesses near the hubs, corroded pins, and poor grounds. Also confirm the 12V battery is healthy — low voltage can set ABS faults on the Geometry C.
• Review live wheel speed data: A good scan tool will show all four wheel speeds. A sensor dropping to zero or reading erratically while driving confirms a signal fault.

Is it safe to keep driving?

In most cases, yes — but with caution. Your normal brakes will still stop the car, but ABS and stability control are disabled, so emergency braking or slippery conditions become less forgiving. If the red brake warning light is also on, the pedal feels strange, or you hear grinding, stop driving and get it inspected. Otherwise, keep speeds moderate, avoid heavy rain or loose surfaces, and book a diagnostic check soon. A wheel speed sensor fault is usually straightforward to fix, and addressing it early prevents bigger ABS or ESP problems.
