Product Overview
1.1 Product Introduction
In LPCD mode, the near field communication module can wake up the NFC device
on the vehicle side when the NFC card or mobile phone is near, and then enter
the standard Polling mode.
When a matching card is detected, the polling mode is activated. LIN informs
VKM and CAN informs BCM to open or close the door.

Operation Instruction
The NFC valid card is placed near the NFC module, and the NFC module transmits
information to the ECU with SE at the end of the car through LIN, and unlocks
the car after the NFC card is certified.
3.1 Setup-Up
Before the module can start normally, it is necessary to prepare a power
supply, a valid NFC card, a wire harness, and a LIN communication tool. In
addition to connecting the NFC reader module, the wiring harness also needs to
connect to the LIN communication tool. After the power supply is powered on,
if the current is about 20mA, the NFC module is started. Figure 3-1 shows the
following。
3.2 Swipe Care
Place a valid NFC card close to the NFC module, as shown in Figure 3-2
3.3 Query Version
3.3.1 LIN Communication
Connect the DB9 port of Kvaser Lin on the wiring harness, connect the USB port
of Kvaser Lin on the PC, and power on the device. The port shown in Figure 3-3
is identified in the device manager on the PC
Click “Connect Device” in the LIN FLASH tool. “LIN Hardware Init OK” is displayed in Figure 3-4, indicating that the Kvaser Lin device is normal.
3.3.2 Query Version
Click “App Version Number” in the LIN FLASH tool, and the message “62 f1 95 02
