ABS Trailer Brake Idiot Light... 2008 ProStar

[the missing link]

I don't know if these helps you but hopefully it will help someone ,
When I ran offroad with a 2000 9900 ( dad and I have a few of them ) the abs light would come on and after spending endless dollars on trying to fix them right , this is what we did .
We switched the low fuel and abs light in the dash , so they both would light up when you turn the key on , the abs would go back out . The only kicker was when you got low on fuel the abs light would come on lol but I don't run a truck under usually 3/8 anyway.
The only time I ever had it ? Was one time I did a cvip and the mech told me it was odd the abs was working with wires broke off on a wheel sensor lol , but he passed it .
