XTOOL CAN FD Adapter for GM 2020-2022 Vehicles

The XTOOL CAN FD Adapter is a high-performance diagnostic tool designed to enhance the capabilities of XTOOL tablet series products for diagnosing ECU systems in vehicles using the CAN FD protocol. This adapter ensures seamless communication and advanced diagnostics for modern GM vehicles, offering easy operation and compatibility with a range of XTOOL tablets.

• CAN FD Protocol Support: Supports the Controller Area Network Flexible Data-Rate (CAN FD) protocol, enabling diagnostics for ECU systems and special functions on GM vehicles (2020-2022), including Buick, Pontiac, Chevrolet, Cadillac, GM, and GMC.

• Compatibility with XTOOL Tablets: Works with XTOOL D7, D8, D8BT, D9, D9 PRO, D9 PRO Master, X100PAD3, EZ400PRO, and A80 PRO Master tablets, requiring a prompt to connect the adapter when selecting a CAN FD model.

• High Performance and Easy Operation: Designed for efficient and user-friendly diagnostics, replacing the standard OBD2 connector on the XTOOL tablet’s main data cable without additional software or hardware.

USAGE

The CANFD connector’s female end attaches to the OBDII-16 connector, while its male end connects directly to the vehicle’s diagnostic port.

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

PRODUCT FEATURES

The XTOOL CAN FD Adapter provides robust functionality to support advanced diagnostics for CAN FD protocol vehicles, ensuring compatibility and high-speed data transmission.

• CAN-FD Data Frame Format: Incorporates EDL bit, BRS bit, and ESI bit in the control field, with a new DLC encoding method and extended CRC algorithm (CRC field up to 21 bits); uses CRC_17 (0-16 Bytes) or CRC_21 (17-64 Bytes) based on data field length; does not support remote frames (no RTR bit).

• CAN-FD Application Scenarios: Supports conversion of existing CAN systems with compatibility rules, including using two separate hardware channels, maintaining the original CAN processor with an improved CAN transceiver, and sleeping the CAN node during CAN-FD communication.

• Vehicle Coverage: Compatible with GM vehicles (2020-2022), including Cadillac Escalade (2021), CT4/CT5 (2020), Chevrolet TRAX/TRACKER (4A), CAVALIER/ONIX (4A), Tahoe (2021), Silverado, Suburban, GMC Yukon, Sierra, Denali, and Buick Envision, GL8 (LSY).

• Usage Instructions: Connects via a female connector to the OBDII-16 and a male connector to the vehicle’s DLC diagnostic socket, ensuring seamless integration with XTOOL tablets.
