SX-CAN — JLR CAN Bus Communication Tool

SX-CAN provides direct CAN bus access for JLR vehicles. Low-level diagnostics, custom message injection, and module communication for advanced programming tasks.

SX-CAN is our own CAN bus communication tool for JLR vehicles. It provides direct access to the vehicle's Controller Area Network (CAN) for low-level diagnostics, custom message injection, and advanced module communication.

What is SX-CAN?

SX-CAN is a specialised tool that connects directly to the vehicle's CAN bus, allowing us to send and receive messages at the protocol level. This is essential for advanced diagnostics, troubleshooting communication faults, and working with modules that require custom message sequences. Standard dealer tools operate at a higher level and cannot perform these low-level tasks.

Key Features

  • Direct CAN bus access — read and write CAN messages directly
  • Custom message injection — send specific messages to test modules
  • Protocol-level diagnostics — identify communication faults
  • Module communication — talk to modules that standard tools cannot reach
  • Multi-CAN support — works with all JLR CAN networks (HS-CAN, MS-CAN, LS-CAN)
  • Gateway bypass — access modules behind gateway restrictions
  • Real-time monitoring — watch live CAN traffic

What Can SX-CAN Do?

  • Diagnose communication faults between modules
  • Test modules with custom message sequences
  • Access modules behind gateway restrictions
  • Monitor live CAN bus traffic for anomalies
  • Inject custom messages for testing and configuration
  • Work with prototype and modified modules
  • Recover modules from communication lockouts
