Hi maxwedge:

I kind of found the location of the EBCM, which is located in the inner splash board of the driver's side front wheel. Should I remove the EBCM unit then measure the connectors in the box that holding the EBCM unit?

Please advise. Thank you!

This can be a tough job to pinpoint the 2 wires for each wheel sensor and check continiuty in the harness back to the sensor, you must use a long jumper, of course, to each sensor wire.

Hi maxwedge:

Glad to hear from you!

Would it be feasible to measure the resistance between two connectors at the bracket box of the EBCM Unit? If the resistance of 4 pairs of connectors to the 4 ABS sensors are close the the resistance of the sensors, then the connectivity might be ok, otherwise there is a open or short.

Please advise, thank you!

The resistance will be higher of course, but I don't know how much over that length of harness, but if is way out of whack you know there is an issue in that circuit.
