Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Outside Door Handle Electronics Module: Notes
The outside door handle electronics are connected to terminal 30F and work within a voltage range of 9 V to 16 V. The Car Access System is directly connected to the data line of the outside door handle electronics. This provides the Car Access System with information about the capacitive sensors and the piezo sensors. The status of the "pull" Hall sensor is monitored directly by the Car Access System.
The outside door handle electronics detect the status of the outside door handle using the sensors.
Each change in the status of the outside door handle module triggers the corresponding function.
These functions are:
- Trigger pulse by inserting a hand into the handle recess of the outside door handle; Capacitive sensor 1
- Unlock request by pulling the outside door handle; Hall sensor
- Lock request by pressing the sensitive area on the outside door handle; capacitive sensor 2 plus piezo sensor.
