Can you drive a car without the ABS module?
Also question is, can you drive a car with a bad ABS module?
When your ABS light comes on it doesn't mean your vehicle isn't safe to drive from point A to point B. The car will still function as normal, it will start up just fine and drive how it always has and your brakes will work as well.
Accordingly, is not having ABS bad?
One of the greatest dangers with your wheels locking up, which ABS pretty much solves, is that when the front tires lock up, you lose the ability to steer your vehicle. During emergency stopping, without ABS, your front tires would have the tendency to lock up.
For example, if an ABS sensor has a broken wire, the entire ABS system will be disabled since the initial self-test will not succeed. The ABS light is yellow for a reason – it indicates that caution should be taken while driving the vehicle, but there is no imminent need to stop.
