My ABS warning light was on for a short period and then the light went off when the car was restarted. What does this mean

everytime you start your car, the abs does a system check. the light will come on when a fault is detected. in most cases, a wheel speed sensor will trigger the light at 15 mph and stay on till re started.
the problem will not go away and needs to be diaged by a shop and then they can give you a bid for the needed repairs.

its normal for system self test but should not stay longer than 30 second depending on make of car or read the owners manual
