I keep getting this code. I have replaced hub, speed sensor, rotor, rotor bracket. I do have continuity on wires from sensor to module. It was engaging ABS every time I would brake at a stop until I changed the rotor and bracket. I think it was rubbing but now I am still getting light and code?

Hello, it sounds like you have a short in the controller. In particular the left front actuation solenoid.

Here is a guise to help you replace it.

Must be missing something, Here is the wiring diagram for the circuit. Double check the connector to make sure one of the terminals has not pulled out of the connector.

I assume the light was on before changing the hub with sensor?

Sorry I meant the other way round, no resistance on left side which is where we seem to have issues I should have resistance correct?
