    I have codes stability controls not working 1066 -6 coming up, on the dash it says “ESC detected erratic, incorrect, or intermittent data from Digital Foot Brake Module! I unplugged the brake power going to the treadle valve and then more codes popped up and was 12v going to it. ABS light stays on. I try to clear it but it doesn’t go away. I’ve disconnected the batteries. Any other ideas?

    Check the wires at each wheel. Disc or drum brakes? Clean out the teeth at each wheel. If there is mud in there it will throw off the computer as it uses the teeth when the wheel rotates or to see if it is locking up.
