What do these codes mean?

basically, if your stereo/nav are working, don't worry about those. they're related to the stereo/nav network.

trouble codes related to the operation of your vehicle are relayed by the obd2 connection and read by a toyota scanner. some other types of scanners can read basic obd2 codes but only the toyota one(s) can get to the hybrid and other proprietary codes.

 

Looks like someone's been poking around the Diagnostics menu inside the MFD.. Fun stuff. The three nybble code is the device
(0x190= HU head unit, 0x110=MFD)
When I first saw this post, I thought you had an AVC Lan sniffer like some of us..

In any case. I think the PDM screen logs 'bad' packets, or error conditions (only within AVC Lan.) The address is probably most important to you. i.e. if you're getting a lot of 'long latency' problems, then this menu might be useful. (even a normal prius has times where it looks like it's lagging while redrawing the screen.)

IIRC, the MFD is only wired to AVC Lan so it can only get info from Gateway (Off the top of my head? Device 0x1C3) So, no DTC's through here, gotta buy a scan tool...

DTC's are usually in the format Pxxxx where xxxx are 4 numbers, there are also two other codes besides 'P' that are ermm a little specific to the Prius (HV ECU dosen't really exist in a 'normal' car..)
