ABS Light On? What It Means on Your Range Rover Sport III

Why your Range Rover Sport III’s ABS light stays on

A continuously lit ABS warning light means the ABS module has logged a fault and disabled the anti-lock braking system. On the Range Rover Sport III, the most common culprit is a wheel speed sensor or its wiring, but it can also be a dirty or damaged tone ring, a worn wheel bearing, a corroded connector, or a voltage issue. The ABS module needs a clean speed signal from all four wheels, so one weak signal is enough to trigger the light.

What to check first

• Scan the ABS module for codes: this usually tells you which wheel is affected, such as front left or rear right. Live wheel-speed data is even better — compare all four readings while rolling slowly.
• Inspect that wheel’s sensor and wiring: look for chafed wires, corrosion at the connector, debris on the sensor tip, or a sensor that is not seated properly.
• Check the tone ring and hub: a cracked, rusty, or dirty reluctor ring can confuse the sensor, and excess wheel-bearing play can cause an intermittent or steady fault.
• Don’t replace the ABS module first: confirm the sensor signal and wiring before condemning expensive parts.

Is it safe to keep driving?

If only the amber ABS light is on and the brakes feel normal, the conventional brakes still work, but ABS, traction control, and stability control may be reduced or unavailable. You can drive carefully to a workshop, but avoid wet or slippery roads, hard braking, towing, and long trips until it is diagnosed. If a red brake warning light appears, the pedal feels soft or long, or you hear grinding or feel pulling, stop driving and arrange recovery — that is a safety issue, not a wait-and-see warning.
