I created a new DIY thread with the book description, conditions, etc for this code: P1875 Explained

Sounds like you have a problem with the circuit between the VCM (under hood) and the TCCM (passenger side kick panel). You should start by checking the continuity from the TCCM and VCM on the wire specified in the schematic.
