ORA Good Cat ABS Light On? Check Wheel Speed Sensors First

What a steady ABS light means on your Good Cat

When the ABS warning light stays on continuously rather than flickering, the ABS module has usually stored a fault code and disabled anti-lock function as a precaution. On an ORA Good Cat, a wheel speed sensor fault is one of the most common reasons, but it is not the only one. I would treat it as a request for diagnosis, not as a cosmetic warning.

Likely causes and what to check first

Start with the easiest and most common items: the wheel speed sensors at each hub, their connectors, and the wiring that runs near the wheel arches. A sensor can be damaged by road debris, a connector can corrode, or a harness can chafe. The tone ring or magnetic encoder on the hub can also crack or collect metallic debris, so the sensor has nothing clean to read.

• Wheel speed sensor and connector: inspect each wheel for a dirty, cracked, or loose sensor and check the plug for corrosion.
• Wiring and tone ring: look for chafed wires and a cracked or contaminated reluctor ring or encoder.
• 12V battery condition: low voltage on an EV can trigger module faults, so check the auxiliary battery and charging system.
• ABS fault codes and live data: scan the ABS module and compare all four wheel speeds while rolling slowly; a dropout will point to the corner at fault.

Is it safe to keep driving?

With only the amber ABS light on, the conventional brakes should still stop the car, but anti-lock assistance is disabled. You can usually drive cautiously to a workshop, but avoid slippery roads, hard emergency braking, and long trips. If the red brake warning light is also on, the pedal feels different, or you see multiple warning lights, stop and get it checked before driving further.
