    Hi Everyone,

    I'm Jeff - I have a 2004 Prius, love it - although I'm a bit taken back by some of the milage statements I read here - I'm averaging around 43 mpg - both city and highway right now. Yes, I've checked the tire inflation level, etc. I try to keep everything changed on or before schedule due...

    Anyway, I downloaded instructions for getting into the system configuration screens for the Prius and came across several "Error Codes" recorded by my Prius. I'm wondering who can tell me what these codes really mean in english?

    LAN MONITOR:
    CODE: SUBCODE:
    01-D5 178-2E-F
    01-D5 440-2E-F
    01-D5 1F0-2E-F
    01-DC 1C6-02-C
    01-DC 190-70-I (Possibly a "1" or even an "L", but couldn't tell)

    Anyone have any idea what these error codes mean? Should I be concerned? Is there some sort of error code conversion tool out there for a PC?

    Any help is appreciated - everyone drive green and safe.

    Update to the error codes thing - which no one seems to be able to tell me what they mean, after a VERY STRANGE incident.

    I took my 04 Prius to a local car wash - no problem there, looked great after coming out of the wash. However upon jumping in the drivers seat and ready to drive away the Prius "Start" button would only glow "Amber" and the battery showed NO BARS at all. Attempting to reset the start button by either pushing on the break and start, or no break and start, followed by several attempts to get it out of "Park" left me sitting in the sun with a Prius that wouldn't start!

    After a few minutes and some warm sun - POOF pushing the power button started the engine with a very alone purple bar at the bottom of the battery display. I drove it immediately to the dealer and they "of course" could not re-create the problem and therefore could not troubleshoot it. So, thanks to the nifty post on viewing error codes I promptly brought the error codes up on the display and "in a snide voice" I said - and who knows how to troubleshoot a Prius at this Toyota Dealer?

    After a very brief moment a very nice person viewed the codes on my display and actually decyphered them for me - while I don't have the exact details, what I know these mean the following:

    Anti-lock break error (I reported an issue with the breaks after purchasing the car in 05 - in the mornings with humidity in the air, or just after a rain the first time I drive away and push the breaks they will pause and then lock a bit. After 1 or 2 times, this seems to go away. Now, I have the utmost faith in technology... yeah.. I admit I'm a tech-geek, the response of "we can't recreate" seems to be the default response to all Prius problems by dealers. Since I reported this well under warranty, if I find out that the error codes that are noting "Anti-Lock Break Error" - are due to the wiring harness problem the dealer in Texas is going to have some problems with me!

    Another error reported was: cold start error
    Another was: Engine Error (rather vague)

    I will actually write down what all of them mean and post once I get the harness replaced - at the time I was just too upset over all of this to spend time jotting them down.

    They ended up ordering a new wiring harness for me under an advisory that came out which extended the warranty for this part to 100k or 96 months. Anyone else had this done and did it correct any issues?

    Oh by the way when the dealer called Toyota to discuss this "Washing car = Dead Batteries" they were rather rudely informed that "Water Damage" is not covered by warranty... So, here I sit thinking, OK - so this is a first for me.. a car that you can not wash?????? - does the warranty also not cover driving in the rain? What an idiot this guy was at Toyota. After some time with a nice customer service person at Toyota, and the dealer finding an advisory on the wiring harness replacement extended warranty - they have ordered the part and I am waiting for them to replace. Hopefully.... this will correct the really strange problem of washing my car = dead Prius...

    Would appreciate any comments or information anyone else has.... :unsure:

    How did you get error codes and what is the LAN MONITOR?

    Thanks

    You have to know the cheat codes:

    Touch screen diags, for 2004 or newer

    Use of this information might result in disabling your vehicle, use it at your own risk.
    • Hold Info button while turning the lights on and off 3 times, you can wait for system checks. -OR-
    Press the display button, then press the left upper and lower corners within the display settings box 3 times.
    o If codes exist press LAN Mon, then CHEK to show codes or hold code clr to clear codes.
    • From the initial screen, hold Info button while turning the lights on and off 3 times
    for Model Info Set Up (type) screen. I do not know what these do, use at your own risk.
    o Types are : 690N 740N 836N 783N 620N 808N 480X 900N 382X 290X
    Types are : 901N EMV AVX(ten) AVX(nat) AVX_HV(ten) AVX_HV(nat) 749N
    • Use the Menu button to reach the Diagnosis Menu, press the Display Check and then
    Vehicle Signal Check to show the accessory battery voltage and other information.
    • From the Diagnosis Menu press upper-left then lower-right screen corners for PDM menu.
    o All buttons except for perhaps the Init. BackUp may be safe to use.
    • From PDM screen, hold Info button while turning the lights on and off 3 times for an untitled screen.
    o Here you find a number of options stating success or PGM rqd including TKM, Flicker,
    setting:Tape/MD, setting Address:110H/120H, setting AC:eek:ff/on, and setting Auto:eek:ff/on
    • Hold the physical Display button to exit at any time, or simply power off the car.

    I'm a bit curious about these myself, but after 10 minutes of googling, I seem to find plenty of stuff on how to read them, but no documentation on what they mean. The closest thing I could find was these, but I don't think they explain the codes you are seeing.

    what wiring harness are you referring to?

    washing car does not necessarily equal dead battery, but sitting in neutral will knock your charge down quite a bit because the car does not recharge the HV battery in neutral.

    the DTCs you are looking at on the MFD are for the audio/nav system, if they're there but the audio/nav are working fine, it was probably a blip in communication that set them. you cannot pull DTCs for ABS or engine without the toyota scantool.

    Not true my friend - ;)

    by entering the LAN monitor mode there is an option you can do to view error codes - I believe you hae to hold down one of the display buttons on the screen for a few seconds and it will allow you to view the LAN error codes on the screen. I do not have a navigation system in this 04 Prius, no bluetooth either. However, there is a way to get to the bluetooth settings from within the menu and adjust the voice "loudness" also. I found this strange that I can adjust bluetooth settings, but the car itself does not have bluetooth installed. I will attempt to gather some screen shots of the process that I used to display the error codes and post to PriusChat so everyone can view.

    As far as accessing the menu - I did not do the (turn your lights 3 times off and on thing), so that's new to me. The process that I used involved was pretty simple - but if you follow this link it is discussed in detail: http://priuschat.com/index.php?showtopic=13328&hl=diagnostic+screen.

    The only thing that I noted in this thread was this:

    Evidently, the orange "CHEK" lights means an error was captured and you can go to the detail screen, and "NoErr" means no error was captured, and you can't go to an additional detail screen. Betting these are minor comm errors that were compensated for by a re-transmit. Not unusual on a LAN, so I wouldn't worry about it. I will compare only 1 detail screen here, the EMV screen. They are comparable:

    Wayne posted this - but the CHEK button does excactly what hooking up an external code detector would have done (per my nice friends at the dealer where I showed them how to access the codes) - you see the list of error codes he had from the diagnostic using the external device gave 4 out of 5 of the same error codes I noted on the CHEK screen.

    Hope this helps some of you - I'm just hoping the "wiring harness replacement" will correct my problems with "WASHING PRIUS = DEAD BATTERY".

    One more thing - for the person who noted that letting the car sit idle in Neutral while going through the wash - unless... and I haven't see this yet.... a battery display can go from ALMOST FULL GREEN to NO BARS in less than 2 minutes with nothing on (not even the headlights) then I suppose this is possible - but if thats the case, wouldn't it have started after coming from the car wash regardless if I had full green bars, or no bars at all?

    I still believe there is some sort of short in the electrical system that, once wet - dumps the batteries due to the short. Only time will tell - I'm waiting for the part to arrive and once they replace I guess I'll roll the dice again and give her a good wash to see what happens.

    I'll keep you all posted.

    so... what wiring harness are they going to replace?

    non-audio/nav system error codes are in the format Pxxxx, Cxxxx, etc, not the format you posted.

    but please do tell how they pulled ABS codes from the audio diagnostic screen. i'd like to hear how they did that.

    the codes are all in Hex, so the last one should be a "1".

    You can find some of the code interpretations in these links:

    Well I guess I am rather confused myself - The guy that was helping me had a device hooked up, I am assuming it was some sort of scanner - but he showed me in a book he had that the codes on my screen were the same as the codes in the scanner. Maybe they are really confused as I am...

    Either way the wiring harness will be replaced and I hope this fixes the problem.

    Anyone else had this happen - washing = dead batteries?

    :eek: Man - I had no idea this was going on. I'm going to see if I can fit under my Prius and see if this is an issue regarding my electrical problem. I am completely amazed that the TSB advisory states to replace the wiring harness, but says nothing about flipping the metal peice that might cause a "rub" on the cable. :angry:

    Will let you know tomorrow if this is a potential reason for my "Washing car = dead Prius".

    Thanks so much for the link, I'm going to print out these pictures and give them to the dealer and have them check also just in case I can't get under the car.

    Appreciate your help!!
