KESS3 Protocol Release

9 october 2026

Upgrade 3.63

New BENCH and BOOT Unlock protocols for Bosch MD1CP017 “Locked” ECUs – Jaguar and Land Rover.

Work on the latest generation of JLR MHEV diesel vehicles.

With KESS3, you can now read and write protected Bosch MD1CP017 ECUs fitted to Jaguar and Land Rover models equipped with 2.0 D165 MHEV and 2.0 D200 MHEV diesel engines, manufactured from 2021 onwards.
To use this mode, you must first unlock the ECU using the dedicated BOOT protocol and the KESS3 Unlock Module.

You can then access the ECU directly through its connector also in BENCH mode to read and write its entire contents, expanding your working possibilities on the Bosch MD1CP017. For subsequent operations, you will no longer need to open the ECU: you can always work directly in BENCH mode.

Real benefits for your workshop:

  • Work on the ECU in BENCH mode after unlocking it in BOOT with the KESS3 Unlock Module.
