Cabin motion detection and vehicle tilt monitoring on the 2023 Cadillac CT5 are managed by ultrasonic interior sensors, vehicle angle gyroscopes, and body control module sirens.
How to Fix It:
-
Arm with Windows Down: Lock the vehicle using the key fob while leaving a front window rolled down to test interior movement detection safely.
-
Trigger Motion Sensor: Wait thirty seconds for the system to arm, then reach through the open window to wave your hand and sound the alarm.
-
Disarm the Alarm: Press the unlock button on your key fob or insert the key into the ignition to silence the horn and flashing lights immediately.
