It’s Safe To Drive Carefully With The ABS Light On. … You can still drive the car with your ABS light on, because it does not impact normal braking. However, we wouldn’t recommend you do this because your ABS system helps to control stopping, and it can be dangerous to be driving without it.
The four common reasons that typically cause this light to turn on include a malfunctioning ABS module, low levels in the fluid reservoir, broken wheel speed sensors, or the system is turned off. Your ABS actually shares some important components with another system in your vehicle: your traction control system.
An ABS control module replacement can range from $320 to over $1,000. The wide price range isn’t really driven by labor cost, which will typically be around $80-$120. It depends on how much the control module costs and how difficult it is to source.
How much does it cost to replace an ABS sensor? ABS wheel sensors cost anywhere from $100 to $200 each, while ABS control modules run from $200 up to $600 apiece. In addition, expect to pay between $80 and $150 per hour for labor and anticipate at least an hour to an hour and a half of work.

One reason your vehicle’s ABS light is on is because it may be sensing abnormally low levels of brake fluid. You’ll be able to notice if your brake fluid is low by the way your car brakes. The braking may seem soft or spongy. However, if the brake fluid is low, you’ll probably see more than just the ABS light come one.
When it is functioning correctly the ABS system is designed specifically to prevent the wheels from locking up during heavy braking, preventing loss of traction. However, there can be certain instances where a faulty ABS module can behave erratically, causing your brakes to lock up even under normal driving conditions.

1. ABS Light is illuminated on the dashboard. Since the wheel speed sensor also monitors the anti-lock braking system on your car, it’s common for the ABS Light to illuminate when the sensor is worn out, disconnected, or has been struck by debris, which means you’ll have to replace the wheel speed sensor.
On many modern cars, a bad wheel bearing will trigger a warning light. The ABS or traction control warnings will often illuminate, since a bad bearing will trip the system to deactivate.
The anti-lock brake system (ABS) may function erratically or illuminate the warning light due a damaged wheel speed sensor. A wheel bearing and/or CV joint with excessive runout can cause the ABS trigger rings to rub against the ABS sensors and damage them.
