Hello, my name is***** step would be to check wiring between wheel speed sensor and abs module. If wiring is good then scope both of the front wheel speed sensors to compare signal and if signal is good replace the abs module. If you unplug abs module and wheel speed sensor, there shouldn't be more then 5 ohms resistance between the two points. Here is a wiring diagram to help with testing, let me know if you run into more questions. Thanks.
