Well I just finished building my CAN reader and my extremely crude CAN interface firmware. Basically I just have it in a listen only mode, that sends everything it reads through a UART connection to a terminal. I have an Excel sheet I found on here (via google I think) that deals mostly with EV/PHEV CAN related messages. But is there a detailed CAN overview of the system? For example, to test, I turned the car on without pressing the brake pedal (pushed power twice), and a few CAN messages came about. Then I turned on the hazard lights, and a new CAN message appeared. None of the SID's (Standard Identification code for a CAN device) or EID's (Extended ID code) match anything on the list. I could very well have a firmware bug, or I might not be capturing the CAN messages correctly yet, but I was hoping for a detailed CAN overview for the Gen II Prius. Does it exist? This is what I sniffed out and parsed without the car being Ready, just On
I should add the decoder: SID: Standard CAN ID isEID: has an Extended CAN ID EID: Extended CAN ID DLCEID: Data Length Code Extended CAN ID RXTXRQ: Request to Transmit on Receipt (Basically, saying I want something back from you after I finish. 1 = yes, 0 = no) DLCLen: Data Length Code Length (how many bytes or bits it is sending back... I am not entirely sure on this yet) RXData[n]: The actual data received where n is between 0 and 7 for a maximum data length of 8 bytes, which is CAN limited...
