KESS3 expands support on mid-power tractors equipped with Stage V engines.

04.05.2026 — Upgrade 3.13

One of the most widespread platforms in the sector is now manageable directly via the diagnostic port.

With the release of the dedicated protocol for Bosch MD1CS069 ECUs, installed on 2.9, 3.4 and 3.6 Stage V engines from 2017 onwards, it is now possible to operate in OBD mode without invasive procedures on the control unit.

A practical solution for professionals working daily on these vehicles, where time and downtime directly impact productivity.

This translates into real advantages for workshops and field operations:

  • direct access via diagnostic port with cable 144300K226

  • continuous vehicle operability

Once connected in OBD, you can perform reading and writing in a simple and linear way, optimizing repair operations and improving performance to handle even the most demanding tasks.
