Well shortly after having flashed my ECU with Uprev , I don't know what happened .
I got the check engine light then I went to see the code , it gave me U1024.

I have no idea why it came out , I was just looking around in the program to familiarize with it. I tried to erase it with Uprev without success.

that is from EC.pdf in the Service Manual

U1024 CAN COMM CIRCUIT
Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex
communication line with high data communication speed and excellent error detection ability. ECM and
VVEL control module are connected with two communication lines (CAN H line and CAN L line) and transmit/
receive data. ECM shares information and links with the VVEL control module during operation.

Anyone have an idea about this ?
