Hi everyone my ABS light comes on and the code is 1-8 which is the high pressure system. The weird thing is that it only does it on a second start up, if the car has been sitting for hours and I start it the light will not come on no matter how long it is running, but the second I shut it off and start it again no matter if its a second right after the first start or down the road. Have any of you experienced that and what could be done to fix it.
