Alientech KESS3 Adds Boot Protocol for GM E67

 Problem: It’s a Seat taraco 2.0tdi 2023 model. Tried to read Bosch ECU MD1CS004 (HW80) with Autotuner. It doesn’t want to read it too high protection but I did a virtual read via obd I’m afraid to write it so it doesn’t crash.

Error:

Authentication error. This ECU has new protection and is not yet supported.


AutoTuner VAG MD1CS004 Authentication Error Solution

Solution:

ok with obd mode by Autotuner.

OBD is ok for this Version.

Virtual is always safe.
Obd read and write no problem.
Obd read and write safe and fast with charger battery.
There are some versions you can’t read it, locked version, 309 AA , M, T. If you want to do adblue off there is another solution.

Use this in Module 30, 1,3,5 — ECU ground (just connect one of the contacts) 77 — CAN-High 78 — CAN-Low 76 — K-Line 2 — +12V (ignition on) 4 — +12V (power supply of the main relay) 6 — +12V (non-switchable power supply) You may not be able to do this ECU in BSL 53 as main processor is MPC756MXP56 Second Processor TC1738. You could try OBD Module 30 Kia/Hyundai SIM2K 2.0L, 2.5L (SIM2K-D160) But failing that, you would have to do this in BSL mode 53 http://www.pcmtuner.org/pcmtuner-module-53-infineon-tricore-bsl-operation/
