- The ABS warning light will come on when the car is started, and it will stay on permanently.
- If you test the brakes on gravel or ice, you will no longer observe the ABS mechanisms kick in, and the brakes will lock up.
How vital is this service
Functional ABS is actually the difference between being able to simultaneously brake and steer past an obstacle, or locking up and hitting it. It’s deemed important enough for insurance companies to offer discounts to owners of vehicles equipped with ABS systems. With a failed speed sensor, you’re driving around with sophisticated electronic control systems, relays and sensors that could save your life. If only they are working.
