Thought I'd pass along this link... it helped me with my P0325 trouble code. Good site. OBD-II Trouble Codes - OBD-II DTC Trouble Codes Repair Help Site
So I have seen lots of lists of "TROUBLE CODES" for the OBD connector, but I am looking for just the opposite. I am looking for a list of codes that you send TO the car that return information about the car. For example, you can request speed, engine RPM, throttle position, etc, and there are a host of other pieces of information available. However, beyond the standard list of codes for requesting info that apply to most cars, I cannot find a Prius specific list of OBD request codes. Does anyone know where I might find such a list?
