Product

Passive Entry passive start system (LF

transmitter and LF transceiver)

Model

B1NA5

Year

2021

Manufacturer

Denso International America, Inc.

1. General description

The B1NA5 system is composed of a BCM (Body Control Module), a maximum of 8 antennas, a

UID (User Identification Device), and an RF Receiver. It is used for locking or unlocking the

vehicle’s door or starting the vehicle’s engine. I.e: When a valid user is identified, the system

locks or unlocks the vehicle’s door or starts the engine.

The BCM is installed in the vehicle and transmits low-frequency wave signals. Depending on the

operational mode, it can use from 1 up to 3 of the installed antennas.

The second generation of BCM employs ASK/OOK for transmission of signaling and challenge

data (UID), operating over a single channel at the frequency of 125 kHz with a rated output

power from 1.58 mW to 4.5 mW.

The RF output power of this device is variable according to the mechanics of the key fob

approaching the BCM, which means that it can operate using half-bridge configurations and

full-bridge configurations at a maximum of 3 antennas at the same time, there are several

antennas configurations according to the car size. There is not any internal software regulating

the BCM or antenna’s behavior.

There are 3 different transmission types that can be used in vehicle applications.

- PEPS (Passive Entry, Passive Start)

- Approach Mode

- Immobilizer Mode

Notes:

- The BCM device can not be operated stand-alone in its intended use.

- For intended use of the BCM device, a data connection to the host vehicle is required.

- The BCM equipment is not available to the end-user. The equipment is manufactured by

Denso International America, Inc and sold to the relevant vehicle manufacturers.

- Damaged BCM’s on a vehicle can only be replaced by the vehicle manufacturer’s

professional authorized repair workshops as calibration and adjustment with dedicated

tools are required after the replacement.

This part doesn’t have any interface for the user and it is hidden by the interior surface of the car. The antennas connected to the BCM are not installed in accessible parts and under regular conditions, the antennas will be kept at a distance greater than 20 cm from the human body anytime.

B1NA5 DRAFT FOR USER MANUAL - COMPLIANCE DOCUMENT v1 The following considerations are needed for the installation: - A vehicle manufacturer shall create an owner’s manual in compliance with each international regulation. The OEM describes in the User Manual all important functions for the end customer for the error-free operation of the BCM. The device’s maximum operating temperature is 85°C.

B1NA5 DRAFT FOR USER MANUAL - COMPLIANCE DOCUMENT v1 Improper antenna positioning will detune the antenna; drive current may be higher or lower than the current setting or antenna resonant frequency may shift. Please follow the guidelines below to prevent antenna detuning and communication failure during operation. - For Air Tuned antennas: Place the antenna on a flat non-metal surface; Keep metal and other antennas away, minimum 30mm, from all directions. Dotted red line shows the metal prohibition area.
