Have ABS / TRACTION CONTROL RED BRAKE light on. I checked the conection , it seemed OK . As for the ground wires to the block , I was only able to get to 2 of them. HERE are the codes i was able to get . C 1214 and C 1248 ALSO showed a RFA code but i didn't get the number, and when i went back through the list it showed RFA was clear. ANY IDEAS
