As the user's hand approaches the capacitive sensor UNLOCK detection area, sensor communicates detection to BCM Module. Then, the corresponding LF antenna on front side is driven by system to send LF challenge to fob(s) to perform the user's identification process. The same principle is used to Lock the vehicle, with a capacitive sensor LOCK detection area. The NFC device tap is used to toggle the vehicle locking status. 2 System Architecture 2.1 Alternative System Architectures Major evaluation criteria for architecture solutions was robustness, proven in use and cost. Therefore the generic system architecture for Capa/NFC sensors proven in use in the generic project was chosen. 2.2 Dynamic Behaviors Dynamic behaviors, i.e. how the systems elements interact with each other dynamically, are mainly driven by the SW. Then, the timings and sequence charts are described in EE/SW Interface (HSI, IMS 161922) and SW Requirements (IMS 161715)

Before to start any test, check for each LED and corresponding output that sensor is working fine: - touch lock area with thumb for at least 300 ms => check lock prox and lock touch function - touch unlock area with hand for at least 200 ms => check unlock prox and unlock touch function - approach TAG against NFC area => check NFC function 6.3.3 Test box function: To set the sensor in “normal mode”, as it is in vehicle configuration without communication with BCM, let the switch in position RF-OFF. To set the sensor in “RF Discovery mode”, set the switch in position RF-ON. The sensor will send continuous WUPA as described in chapter “actuator test”. To check no loss of detection Tag provided by continental shall lay against the DHS in front of NFC Area as describe in chapter”NFC detection area”.
