What Is CAN FD?
CAN FD, short for Controller Area Network Flexible Data-Rate, is an enhanced version of the traditional CAN protocol used for communication between electronic control modules in modern vehicles. CAN FD allows more data to be transmitted in each message and supports higher data rates during part of the communication process.
As newer vehicles use increasingly complex electronic systems, CAN FD helps support faster communication between control modules. A compatible CAN FD scanner or diagnostic scan tool is therefore important when working on vehicles that use this communication protocol.
Why Is CAN FD Important for Vehicle Diagnostics?
Diagnostic scanners need to communicate correctly with a vehicle's electronic control modules. If a vehicle uses CAN FD, the diagnostic tool must support the protocol in order to access compatible systems and perform supported diagnostic functions.
* CAN FD availability and diagnostic coverage vary by vehicle make, model, year, system, and scanner model.
CAN vs. CAN FD: What's the Difference?
Traditional CAN and CAN FD are both vehicle communication protocols, but CAN FD was designed to support larger data payloads and higher data transfer rates. This makes it better suited to the growing communication demands of newer vehicle electronic systems.
| Feature | Traditional CAN | CAN FD |
|---|---|---|
| Maximum Data Payload | Up to 8 bytes | Up to 64 bytes |
| Flexible Data Rate | — | ✓ |
| Higher Data Transfer Capability | Limited | ✓ |
| Used in Modern Vehicles | ✓ | ✓ |
| Requires Compatible Diagnostic Tool | Standard CAN Support | CAN FD Support |
* Actual vehicle communication requirements vary by manufacturer, model, year, and system.
Why Do You Need a CAN FD Scanner?
If you regularly diagnose newer vehicles, choosing a CAN FD scan tool can help ensure compatibility with supported CAN FD vehicle systems. A scanner without CAN FD support may not be able to communicate with certain modules on compatible vehicles.
When comparing CAN FD diagnostic scanners, consider not only protocol support but also vehicle coverage and other advanced diagnostic capabilities.
Autel offers professional diagnostic scanners with CAN FD support for different levels of automotive repair. Compare the models above to find the right CAN FD scanner for your diagnostic needs.
Frequently Asked Questions
What is CAN FD?
CAN FD stands for Controller Area Network Flexible Data-Rate. It is an enhanced version of the traditional CAN communication protocol that supports larger data payloads and higher data transfer rates.
What is the difference between CAN and CAN FD?
Traditional CAN supports up to 8 bytes of data in a message, while CAN FD can support up to 64 bytes and allows a higher data rate during the data phase of communication.
Do I need a CAN FD scanner?
If you diagnose vehicles that use CAN FD communication, you need a compatible diagnostic scanner to communicate with supported CAN FD systems and modules.
Can a regular OBD2 scanner diagnose CAN FD vehicles?
Not necessarily. A scanner must specifically support CAN FD communication to access systems that require the protocol. Vehicle and function coverage also varies by scanner model.
Which Autel scanners support CAN FD?
Many newer Autel professional diagnostic scanners support CAN FD. Support varies by scanner model and vehicle, so check the individual product specifications and compatibility before purchasing.
