If you plan to connect to the ECU on the bench, you will also need to power it up. There are three pins each where you need to apply ground (#25, #47, #62) and +12V power (#1, #23, #43). I made this simple harness with insulated alligator clips.

Here's a brief guide on how to connect to the CAN bus on a Trionic7 ECU.

CAN bus connection offers a fast and convenient way to read or flash the firmware in the ECU. However, keep in mind that there's a slight chance it may fail while writing the memory, especially if you're flashing in the car. When that happens, you end up with a dead ECU, which no longer responds to a CAN connection. The only way to revive it in this case is by using a BDM interface.
