KESS3 Protocol Release

5 august 2026

Upgrade 3.40

New OBD protocol for Continental SID208 ECUs – Fiat, PSA.

KESS3 and Powergate now support light commercial vehicles with 2.2 Multijet and HDi engines, also via the diagnostic port.

Thanks to this update, you can work on Continental SID208 ECUs in OBD mode with KESS3 and Powergate, directly through the vehicle’s diagnostic port, performing read and write operations on the engine ECU.

The new protocol complements the already supported BENCH mode, expanding the range of operations available on diesel light commercial vehicles such as Ducato, Boxer, Jumper and Relay from 2011 onwards.

Work on the widely used 2.2 HDi and 2.2 Mjet diesel engines with a range of benefits for your daily work:

  • Direct connection through the diagnostic port
  • BENCH mode already available
  • ECU reading and writing
  • Support with KESS3 and Powergate
  • New opportunities on Citroën, Fiat and Peugeot commercial vehicles
  • Coverage of widely used diesel applications across different international markets

This new support makes working on Continental SID208 ECUs more immediate, expanding coverage for some of the diesel commercial vehicles most widely found in fleets worldwide.
