4.3 Connector and pinout
NOTICE
Risk of damage to the connector and/or its counterpart if disconnected
and not protected
The connector's IP protection grade is only guaranteed when connected to its
counterpart.
Exposure of connector and counterpart contacts to air and moisture can cause an
oxide layer to accumulate on their surface. This can lead to a reduction in electrical
performance, loss of efficiency and malfunctions.
1) To ensure IP protection grade, keep the connector connected to its counterpart
2) Do not disconnect the connector counterpart unless it is necessary to remove
the device from its housing
3) In the case of a disconnection, protect the connection and the connector
counterpart

If the Keyless Keyfob battery is depleted, BLE identification is not possible and related functions
(e.g., vehicle unlock and start) cannot be authorized.
NOTICE
Risk of system malfunction if NFC is not enabled via the VT3 Visual
Tool library function
1) Implement NFC management function in the application software using the
specific VT3 Visual Tool library function vt3_customer_app

Keyfob recognition via external antenna (for vehicle access — if supported)
INFORMATION NOTE
Follow this procedure only if vehicle door unlocking is controlled by
the Keyless system (function implemented via VT3 visual tool).
1. Place the button side of the Keyfob associated with the vehicle close to the top side of the
external antenna
2. Wait 2s seconds. The external antenna detects the Keyfob via NFC and sends a CAN message
to the ECU. The ECU forwards the event to the application, where the related actions (e.g., door
unlock) can be implemented using the VT3 Visual Tool..
If the key is not detected, remove the key and repeat the operation.
Keyfob recognition via ECU for vehicle start up
INFORMATION NOTE
Follow this procedure only if vehicle start is controlled by the Keyless
system (function implemented via VT3 Visual Tool).
3. Place the button side of the Keyfob associated with the vehicle close to the ECU pushbutton.
4. Wait 2s seconds. The ECU detects the Keyfob via NFC and forwards the event to the
application, where the related actions (e.g., vehicle start up) can be implemented using the VT3
Visual Tool.
If the key is not detected, remove the key and repeat the operation.
5. Start the vehicle within xx seconds before the ECU loses the association.
The association time depends on a timer that must be implemented using the VT3 Visual Tool.
