Jetour Ice Cream ABS Light Stays On: Wheel Speed Sensor Faults Explained

What That Steady ABS Light Is Actually Telling You

If the ABS warning light on your Jetour Ice Cream comes on and simply stays on — no flashing, no going out after a restart — the ABS control module has detected a fault it can't ignore and has switched the anti-lock system off. The important part is that your ordinary hydraulic brakes still work, so you have normal braking. What you've lost is the pulsing, wheel-by-wheel modulation that stops the wheels locking up in a hard or slippery stop. On this little EV it also often knocks out related functions such as traction control, stability control and sometimes regenerative braking, because all of them rely on the same wheel speed data. In the vast majority of Ice Creams I've seen with this complaint, the culprit is a wheel speed sensor, its wiring, or the magnetic encoder ring that the sensor reads.

The Usual Suspects, Most Likely First

• Wheel speed sensor (most common). One of the four sensors has failed internally, gone open-circuit, or is covered in metallic brake dust. A single bad sensor is enough to light the lamp and disable ABS.
• Magnetic encoder ring or tone ring. On modern hubs like the Ice Cream uses, the sensor reads a magnetic ring built into the wheel bearing or hub. If that ring is cracked, rusted, packed with debris or has picked up metal shavings, the signal drops out and the light comes on — even though the sensor itself tests fine.
• Wiring and connectors. The sensor leads run near the strut and wheel arch, where they flex constantly and meet water, salt and road grit. Chafed insulation, a corroded plug or a broken pin will produce exactly the same symptom.
• Low battery voltage or a blown ABS fuse. Small EVs are sensitive to voltage. A weak 12V battery, poor charging or a blown ABS fuse can trigger the lamp with no sensor fault at all.
• ABS module or pump fault. Least likely, but if every sensor and all the wiring check out, the module or its pump motor is the next step.

Where a Mechanic Should Start Looking

The first move is always to plug in a scan tool that can read the ABS module — not just a generic engine-code reader. The stored code will usually name the corner at fault (front left, rear right and so on) and turn a guessing game into a ten-minute job. After that, expect a visual inspection of each sensor and connector, a resistance and live-data check of the sensor signal while the wheel is spun by hand, and a close look at the encoder ring for cracks, rust or debris. It's also worth checking tyre sizes and pressures across all four wheels, because a mismatched tyre can create a speed difference the module reads as a fault. Cleaning a sensor or ring often cures the problem; if the ring is damaged, it generally means replacing the hub or bearing assembly, and a failed sensor gets replaced outright.

Is It Safe to Keep Driving?

If the ABS light is the only warning showing, the brake pedal feels normal and the car stops straight and confidently, you can drive it — but treat it as a warning, not a decoration. You have no anti-lock braking, so in the wet, on gravel or in an emergency stop the wheels can lock and the car can slide or lose steering. Brake earlier, leave more distance, and get it diagnosed soon rather than eventually. Stop driving and call for help if the red brake warning light is on as well, if the pedal feels soft or sinks, if the car pulls to one side under braking, or if you hear grinding — those point to a hydraulic problem, not just a sensor. And don't put it off for months: a small, cheap wheel speed sensor job today is far better than a damaged module or an accident tomorrow.
