+36 1 879-7081 Budapest 08.01.2021 Functional Description of radio frequency transceiver for MQB BCM Product: BCM (Body Computer Module) Brand Name: Bosch Model Name: BR21 Hardware version: HW24 1 General Description The radio frequency transceiver is part of a body computer ECU. The ECU in-

corporates several HW-inputs and HW-outputs, which monitor and control body computer functionalities in a car (e.g. light control and central door lock-

ing). The ECU consists of a plastic housing, PCB, electronic components and con-

nector pins. The radio frequency transceiver functionality will be explained in more detail in the below documented sections. Seite 2 von 10 Von XC-AN/PAB2-Bp Bearbeiter Szentannai Zsolt Telefon-Durchwahl

+36 1 879-7081 Budapest 08.01.2021 2 HW Interface The radio frequency transceiver is supplied via the specified connector pins. The antenna of the radio frequency transceiver is a PCB-edge antenna, which is incorporated in the PCB of the ECU. 2.1 Connector Position on housing 2.2 Supply and GND pins:

+36 1 879-7081 Budapest 08.01.2021 Functional description The radio frequency transceiver is part of a remote keyless entry system of a vehicle central door locking system. This vehicle central door locking system consist out of Remote control key with UHF transmitter (NOT part of the MQB BCM) Radio frequency transceiver with PCB-Antenna (part of the MQB Door ECU, which can drive the car door locks to lock or unlock the car

(NOT part of the MQB BCM) Door locks for the central door locking functionality (NOT part of the BCM) MQB BCM) The transceiver has a self-polling mode and is permanently scanning for valid key data, with matching characteristics.

(Note: This data are typically received, when a valid remote control key is in range and one of its push-buttons is pressed.) When the data are matching the characteristics, the transceiver will hand over this data to the micro controller of the MQB BCM. With the help of this micro controller, it is validated, whether this data have been transmitted from the authorized remote control key. When the validation was successful, the MQB BCM will send this information via a CAN-network to the door ECU. This door ECU will drive the connected door lock according to the wish of the operator, who pressed the push button of the remote control key. Hence the doors will be locked or unlocked. The MQB BCM needs to be programmed by the OEM, after installing the ECU into the car. Once programmed, the transceiver is operable directly after ap-

plying power to the connector pins. Seite 7 von 10 Von XC-AN/PAB2-Bp Bearbeiter Szentannai Zsolt Telefon-Durchwahl
