Product Information
Product Name: NFC
Version: 1.0
Release Date: Jul, 5th, 2023
Manufacturer: DIAS Automotive Electronic
Systems Co.,Ltd.
Product Overview
The NFC module is designed to enable near field communication
between a vehicle and an NFC card or mobile phone. It operates in
LPCD mode to wake up the NFC device on the vehicle side when a
compatible card or phone is detected. It then enters the standard
Polling mode, where it can activate other vehicle systems such as
opening or closing doors.

| LIN communication | Informs VKM (Vehicle Key Module) |
| CAN communication | Informs BCM (Body Control Module) |
Product Usage Instructions
1. Setup-Up
To set up the NFC module, follow these steps:
- Ensure that the NFC module is properly connected to the
vehicle’s system. - Make sure that the NFC card or mobile phone is within close
proximity to the NFC module. - Wait for the NFC module to detect the card or phone and enter
Polling mode.
2. Swipe Care
When using the NFC module, be careful to swipe the NFC card or
mobile phone smoothly and without too much force. This will ensure
proper detection and activation of the Polling mode.
3. Query Version
To query the version of the NFC module, follow these steps:
- Establish LIN communication with the VKM.
- Send a query command to the NFC module.
- Receive the version information from the NFC module.
3.3.1 LIN Communication
LIN communication is established between the NFC module and the
VKM. This allows for data exchange and control commands.
3.3.2 Query Version
The query version command is used to retrieve the version
information of the NFC module.
4. FCCID
The FCCID (Federal Communications Commission ID) of the NFC
module is not provided in this user manual. Please refer to the

1 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.

3 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
