New KESS3 OBD protocol for Phoenix L33M – Claas and John Deere

With KESS3, read and write Phoenix L33M ECUs via OBD on the latest Claas and John Deere tractors produced from 2025 onwards.

This new development for the agricultural sector lets you work directly on the ECU through the vehicle’s diagnostic port, with no physical intervention on the control unit. A solution designed to make work fast and practical even when the tractor is in the field, minimizing machine downtime.

The real benefits for the workshop:

• Read and write the ECU through the diagnostic port
• Faster operations, even directly in the field
• Support for Claas and John Deere tractors from 2025 onwards
• Dedicated coverage for PowerTech 6.8L engines

Expand your workshop services with support for the latest-generation Claas and John Deere tractors and work with maximum speed on applications widely used in the agricultural sector.
