DTC PZ2719, UTD - Trunk Tamper Switch Fault: Notes
WARNING: This page is about a different car, the 1996 Cadillac Seville and 1996 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
A test is run to determine if trunk tamper switch is active when PZM is in a off, idle, ready to arm, arm initiated or arm delay state. DTC PZ2719 will set when PZM determines trunk tamper switch has been active for 2 seconds. When DTC PZ2719 is set, UTD will still arm, disregarding input from trunk tamper switch. DTC PZ2719 will clear when PZM does not determine trunk tamper switch as active for 2 consecutive monitoring cycles.
