Supported diagnostic services for 24V trucks

24V diagnostic profiles are developed according to OEM dealer diagnostic standards.

  • Dealer/OEM diagnostic tools are supported
  • Aftermarket diagnostic tools may not fully comply with OEM standards and are not guaranteed to function correctly

Programming (Beta)

Programming (flashing) control units is available as a beta feature and is performed at the user’s own risk.

  • Programming over CAN is possible but not guaranteed
  • Programming over K-Line is not recommended

K-Line is an outdated protocol and lacks proper error handling and latency management, which significantly increases the risk of failure.

Jifeline will continue optimizing 24V profiles and plugins throughout 2026.

Supported services

The following diagnostic services are supported on most 24V trucks:

  • Fault code read-out
  • Live data
  • Coding and learning functions
  • Calibration of new components
