The wiring harness connects to the EPB motor that is on the back side of the caliper. The issue could be a bad EPB motor (speculation, no first hand experience). You could try disconnecting the harness at the EPB motor and seeing if that changes the error code. Ideally you would have access to the factory repair manual as it would likely have troubleshooting sequences for EPB errors. You may find something useful in the manuals that are mentioned in this thread.
