The Alarm Is Activated When The Electric Engine Heater Is Activated

Background

BCM software does not disconnect the ultrasound sensor of the alarm when the electronic engine heater is activated.

If the car is equipped with theft protection with movement detector then there is a risk that the car will trigger false alarms when the heater is activated.

To avoid this there is an option to set the movement detector with the diagnostic tool so that it is deactivated when the heater is active, to then be reactivated when the heater is inactive.
