XTOOL CAN FD Adapter for GM 2020+ Chevrolet GMC Buick Cadillac ECU Diagnostics
2026 XTOOL CAN FD Adapter for GM Vehicles Chevrolet GMC Buick Cadillac ECU Diagnostic Interface CANFD Protocol Accessory for XTOOL Scan Tablets GM 2020+ Models (Latest 2025-2026 Hardware Version)
The XTOOL CAN FD Adapter is a professional diagnostic accessory designed to enable ECU diagnostics on GM vehicles using the CAN FD protocol. It ensures full compatibility with modern Chevrolet, GMC, Buick, and Cadillac models when used with XTOOL diagnostic tablets. This essential adapter unlocks complete system access, fast data transmission, and reliable performance on all CAN FD-equipped GM vehicles from 2020 onwards, including the latest 2025-2026 models.
🔹 Product Description – In-Depth & Detailed
🚗 Advanced CAN FD Diagnostic Solution
The XTOOL CAN FD Adapter is an essential add-on tool engineered specifically for modern vehicles that communicate using the CAN FD (Controller Area Network Flexible Data-Rate) protocol. Many GM vehicles from 2020 and newer utilize CAN FD, and standard OBD2 connections alone cannot access all ECU systems. This adapter bridges that gap, allowing XTOOL diagnostic tablets to communicate accurately and efficiently with these advanced vehicle networks.
What is CAN FD and Why Is It Required?
CAN FD is an advanced evolution of the classic CAN bus protocol (ISO 11898-1). It supports data transmission speeds up to 5-8 times faster and allows larger data payloads (up to 64 bytes per frame vs 8 bytes in classic CAN). This is critical for modern vehicles with complex ECUs, advanced driver assistance systems (ADAS), infotainment, and high-bandwidth modules. Without CAN FD support, diagnostic tools cannot fully communicate with many 2020+ GM vehicle systems, resulting in incomplete scans, missing live data, or inability to clear certain DTCs.
The XTOOL CAN FD Adapter adds full CAN FD compatibility to supported XTOOL tablets, enabling OE-level diagnostics, faster data streaming, and complete access to all electronic control units.
🔧 Designed for GM Vehicles (CAN FD Enabled)
This adapter is purpose-built to support General Motors CAN FD platforms, including:
Chevrolet
GMC
Buick
Cadillac
It enables stable ECU communication for diagnostics, fault code reading, clearing, live data access, and system scans on supported GM models equipped with CAN FD architecture.
🧠 Seamless Integration with XTOOL Diagnostic Tablets

XTOOL CAN FD Adapter Work for GM 2020-2022
Xtool CANFD Adapter is designed for diagnosing ECU systems of cars meeting with CANFD protocols. It's used with XTOOL's tablets series products. It's high performance and easy operation. When the user selects the CANFD model, if the current device does not support CANFD communication, the user needs to be prompted to use the CANFD adapter to connect.
XTOOL CAN FD Adapter will be compatible with XTOOL Tablet Like D7/D8/D8BT, D9/D9 PRO/A80 PRO Master.
USAGE
Use female connector connecting with OBDII-16 and male Connector connecting with DLC Diag Socket.
CAN-FD data frame format
*CAN-FD data frame newly adds EDL bit, BRS bit, ESI bit in the control field, and adopts new DLC encoding method and new CRC algorithm (CRC field is extended to 21 bits)
*According to the length of the data field, different CRCs are used, such as CRC_17 (0-16Bytes), CRC21 (17-64Bytes)
*Does not support remote frames (no RTR bit)
CAN-FD application scenarios
For the conversion of the existing CAN system, the current mainstream has the following rules for compatibility with CAN and CAN-FD:
*Use separate two hardware channels in one system
*Under the unified platform, keep the original CAN processor and improve the CAN transceiver
*When using CAN-FD communication, sleep CAN node
Extended Vehicle Coverage (2020-2026 GM CAN FD Models)
CAN FD adapter can work with many car models, like Chevrolet, Cadillac, GMC, Buick and etc.
