Does anyone know what serial communication protocols are used in Scion cars? I know they use CAN but I don't think it's used throughout the car's electronics.

I captured this stream of serial data and I'm trying to determine the protocol. The baud rate is 2.4k. I don't think it's CAN because the baud rate is too low. I thought that the protocol is local Interconnect Network (LIN) but the frame format doesn't seem to match.

Could somebody help me determine the protocol type or give me hints on how to do it?
