Some 2018-2019 Escape, Transit Connect and EcoSport vehicles equipped with a keyed ignition and a factory invoiced accessory (FIA) VSS may exhibit intermittent alarm activation with lights flashing and the horn sounding after a loud noise and/or shockwave near the vehicle (ex. large truck passing, garage door slamming closed). The root cause of this concern may be an incorrect shock sensor sensitivity adjustment on the VSS module. Perform the shock sensor sensitivity adjustment procedure outlined in the vehicle security/remote start installation guide located on the PTS website. The shock sensor requires adjustment during the installation of a vehicle security/remote start system. The shock sensor sensitivity adjustment procedure should be performed following the installation instructions.
