Iam new to this community, but need help! Spent 3 days of reading and searching. I need to start Instrument Cluster on bench via CAN command. The IC have old firmware and in car does not accept can commands,but mcu see it with error (fw mismatch).
Who can share with me what i should send to IC via can to boot it up?
Power and so on is ok, only need can ID and hex string to wake up it.
Thanks for help!

I think that this forum is more about making vehicles spin the wheels and charge. Much less about making it look fancy and having infotainment. But nonetheless good luck out there! Perhaps MitM device could spoof the correct fw.

MCU1 IC wakes up with IP network from center display not CANBUS. Make an ethernet cable to the IC and send network packets.
