abs/inop light

if i let my car sit like 2 days before is tart it and sometimes even over night it will come on when i start it the first time....but i can turn the car off and back on and the light goes away....anyone know what the problem is????

tttttttttt

Could be moisture affecting one of the wheel sensors, or the harness connector for the sensor. You can have someone pull the codes from the EBCM with a high-end scanner, to find out exactly what the problem is.

didnt know that....ill get that done this week....will it still be in there if the light is gone???

now i just need to fix my high idle
