Monitoring CAN I can see something strange-when the engine is shutoff CAN signal can't be decoded,something strange is captured.Before of engine shutoff I have a CAN command what turn off main relay,someone can help me to identify the sender of this message(ID 2-30)?

Hi Victor, thanks for the post.

I cannot help with ID 2 30 but I am in the process of creating a forum post looking at CAN ID's and how to use a number of PicoScope hardware and software features to provide further information about "ID" origins within CAN.

Here is a link that will assist with CAN ID's

Take care.....Steve

Hello,
Thank you for your support Steve.
Today I made a new capture with CAN H&L,+15 from ignition key and +15 from EAM module to ECU.Something wrong is happening in EAM module

Hello,
Faulty EAM was the source of engine erratic shutoff.
