Hello, my name is ***** ***** I'm here to help get your problem solved.

Expert:  Dan replied 11 months ago.

The common problem to cause this code is a wheel speed sensor harness. Start by inspecting connector condition and if damaged fix/replace. If good then check resistance between wheel speed sensor wires and abs module, each wire should have under 5 ohms resistance. If either wire has higher resistance then follow wire to find damage. Give me a minute and I'll upload wire diagram to help with testing.
