Your not going to believe this. I too have been fighting the ABS and Brake light intermittantly coming on, also. I'm sure this is just a coincidence but it has been 3 weeks and they haven't come on. I first cleaned the Frame Grounds as reccomended, no help.
1 day as they were both on, I got a "Low wiper fluid" in the message center. I filled it to the brim and...no more "ABS" and "Brake" lights. I know it doesn't make sense and I have been reluctant to say a word about it fearing a "JINX" and it would come back on.
It was happening at least once a day and has been a full 3 weeks without coming on.
You got me? Only thing I can think of is somewhere in the schematics they are linked, IF this truly fixes it. I hope I put this in the right place!! Please reply with your comments!
