The yellow antilock light goes on when I start the car then turns off after a couple of seconds. Once I start to roll the light comes back on.. What does this mean and how do I diagnose the problem??? Also the antilock breaks definitely do not antilock when the yellow light is on..

the abs dont work when the abs light is on is because when the light is on, there is a problem with the abs. If the abs has a issue, it defaults to not working have you got abs codes? the diagnosis connector is by the spare tire
