Foxflash Cannot Connect to Chevrolet Delphi MT80 ECU

 Problem: I need to perform an "immo off" on a 2010 Chevrolet Aveo with a Delphi MT80 ECU. I’ve used the FoxFlash pinout, but I can’t get it to connect. Can anyone give me a hand?

Here is the clue.

Suggestions:

1). Increase voltage, give power supply at 14.5V.

2). Use a 120-ohm resistor between CANS.

3). In bench mode, set it to 3.3V, not 5V.

4). Some people use the pinout from KTAG/KESS3 with pin lift from Tricore MCU.

Then, you can make the connection and do a full read.

5). Some also use godiag tricore cable to do a boot connection. It works fine.

Example:

Chevrolet Aveo T255
