The 8504D Digital Shock, Tilt, and Temperature Sensor is an add-on security sensor designed for DS4 and DS4+ systems. It adds an extra layer of protection by detecting impact and vibration, sensing vehicle tilt (such as jacking or tow attempts), and monitoring temperature to support automatic remote start when conditions are too hot or too cold. It connects via D2D 2.0 for a clean, integrated install and can be tuned to match the vehicle and customer sensitivity preferences.

• D2D 2.0 compatible with DS4 / DS4+ systems

• Fully adjustable digital shock + tilt combo sensor for improved security detection

• Warn Away and Full Trigger responses for light impacts vs. confirmed events

• Tilt angle adjustable from 1–3 degrees to help detect lift or tow activity

• 15-level shock sensitivity adjustment for dialed-in performance

• Built-in temperature sensor supports automatic remote start when outside temps are too hot or too cold
