DIAS Automotive Electronic C234 NFC Reader Module
Product Overview
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.

Assembly Introduction
The C234 is placed inside the door handle and do not require extra fixing. Figure 2 3 show the installation positions.
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.
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 communicat ion 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.
Swipe Care
Place a valid NFC card close to the NFC module, as shown in Figure 3-2.
Query Version
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.
Query Version
- Click “App Version Number” in the LIN FLASH tool, and the message “62 f1 95 02 06 01 04 14 00.” is displayed in Figure 3 5. Indicates that the version information of F195 is read.
