Pictures of '06 Diagnostics Screens

In an earlier thread (http://priuschat.com/index.php?showtopic=13280&hl=) I offered to post pictures of the '06 Prius diagnistics screens and menus. There seems to be demand for it, so here it goes...

I'll try to group similar pictures together, but in general, the pictures shown will be in the order of transversal through the menu tree. The buttons and sub-menus are labeled fairly well, for the most part, so most of this should be fairly self-explanatory. In a few cases, I did not venture down some of the menu/screen options, as I worried about the potential impact. I've only had the car a couple of days, I want to keep it operational. Earlier stories about Diagnostics menu miscues have me a bit uneasy about some of these.

First, as noted in the earlier thread, the '06 Prius (in all models with the higher-res screen -- all but the #1 option package) has a Toyota logo and name "splash" page, and not a Prius logo when the car is first turned on. See attached.

As I am not familiar with the '04/'05 screens, it would be interesting to me to find out what is the same and what is different (new or missing). Any details on how to interpret some of the data given would also be useful. More pictures, in groups, will be added to this thread.

 

Getting to the diagnostics menu is apparently the same in the '06 -- Display, then Upper left, lower left, upper left, lower left. I will not give more explicit instructions than this, as it is documented so well elsewhere. If you have questions on the exact sequence, search the Forum. There is now a Knowledge Base articles on hacks and Easter Eggs that is very informative. Be careful as you experiment, however.

Upon entering this sequence, the System Check Mode screen appears (see first picture). There are four option buttons at the bottom, only one of which (LAN Monitor) has an additional screen. Oddly, I found codes for the EMV (what's that -- I need to check the acronym posting), Navi, and DSP-AMP. Not sure where these came from, or how frequently the codes might be generated. The car has ~100 miles on it, and I've only had it 2 days. Not good to be getting error codes already, in my mind.

To leave this screen, the only option "forward" is the Menu button on the top right (or powering off the car).

 

Selecting "Menu" from the System Check Mode screen brings up the Diagnosis Menu. Oddly, the first menu item (Service Check) brings you back the the System Check Mode screen. This must be used most often for them to make it the point of entry from the Easter Egg. Kinda odd it doesn't just put you in the Diagnosis Menu directly.

Skipping down the menu, we go to Display Check, and its submenus/screens, as attached. I was not able to get anything to display on the panel switch screen, even though I tweaked numerous knobs and switches on the instrument panel -- not sure what this one does, exactly. Similarly, the Vehicle Signal Check Mode screen looks a little boring since I was not in IG-ON, and therefore all was quiescent. The Mic&Voice Recognition Test Check was live -- you'd speak and the instantaneous volume of your voice would register in the squares you see in the screen. Due to time, I didn't play with the Record/Play functionality, which you'll see elsewhere as well. Getting back to the Diagnosis Menu requires hitting the option in the top right a few times, depending on where you are in the tree.

 

The Navigation System Check is next in line. All screens in this tree are shown in the attached. To maintain some privacy, I've obscured the exact GPS coordinates, lest someone use them to smart bomb my garage!

I did not try the Memory Copy/Paste, lest that mess things up (and I had no "back up tool" connected to the car). Also, the Parts Information screen is of note. When I check the DVD version number via the normal approach in the non-diagnostic Nav menus, I am told its version 05-01, which I believe from other posts is the latest and greatest shipping with the last '05's. This Parts Information screen seems to indicate the DVD version is later in my car (unless I am misinterpreting it). It may simply have to do with the differences in the NAV system this year. It displays lane configurations for you at major intersections, so you can be positioned in the proper lane as you move into and through it (I'll post pictures of this after some driving tomorrow), and perhaps that requires data that is not in the '05 DVD.

In any case, you get back to the Diagnosis Menu again from the button in the top right corner.

EDIT: Camera Check is grayed out in that screen. No diag for that yet, but they made provision for it in the GUI?

 

The Bluetooth Check menu is next. Some interesting options to explore here. I think this screen or something like it was in earlier models, per discussion I've seen. However, just to add some foreshadowing, there is a later screen with even more juicy and fine-grained ways to tune Bluetooth.

Having finished the Bluetooth menu and sub-menus, I thought I was done, but with a little exploring, I learned I was wrong...

 

So, after going through all these menus, and sub-menus, I finally climbed back up the tree to the main Diagnosis Menu. At this point, I figured I was done, but I casually tried an upperLeft-lowerLeft-upperLeft-lowerLeft sequence.

Alas, that did not work. I started to play around almost randomly, touching the four corners, none of which had a GUI button in it. All of a sudden, the screen changed, and I wasn't sure how I got there. I powered off, and re-tried what I thought worked, and then simplified it to the basic requirement.

Hit Upper Left and then the Lower Right corners on this screen, and you go to a larger, deeper diagnostics menu...

 

And, here it is. Some of the options on this menu scared me a bit, so I did not select them. For those I did try, the screens obtained are included below.

A couple of things I found interesting in this Product Diagnosis Menu:

1) What is the MM Diagnosis Recorder? Anyone know? In the Display MM Diagnostics Recorder screen, it indicates that IEEE 1394 can be used as the transfer method (although its grayed out -- maybe cannot be changed?). Does this mean the Prius has FireWire built into it somewhere. There are enough xCU's in the technical documentation that one of them might have a FireWire port somewhere.

2) The Touch SW Adjust screen ended up being something that looked like it would tweak my touchscreen calibration (the picture with the crosshairs and little else). Scared that would be a BAD thing, I powered down as soon as I got this screen, not wanting to touch anywhere to go back, lest I mess it up.

3) The Vehicle Signal Test looks similar to, but not identical, to a sub-menu we saw earlier under the Nav Diagnostics menu.

4) The TEL Voice screen looks VERY interesting. It looks like you can select individual algorithm parameters, like the Bluetooth Receive Gamma used to compress the voice, and set them as desired. This could make things very bad, but if you know what you are doing (know the algorithm!), it might be a good way to optimize things.

OK, I could not find any more hidden screens or menus.

So, for those of us that don't have an earlier model, how does this compare with the '04/'05? I have seen anecdotes about their diagnostics menu, but have never seen details on how any of these screens can really be used effectively. If '04/'05 owners understand these better than me, can you comment on them? There is a gob of things to cover, so I posted these in logical groups. I'd love to understand how to tweak Bluetooth, for example, if someone has read how in the tech manuals and/or knows the BT parameters (many more in the list that I do not show).

Comments?

 

Yes, I didn't take a picture of everything -- just the major screens.

I was away all weekend. Just getting back to PC now...

 

Wayne,

Thanks for your comparisons. It looks like things are basically the same, except for the override, a couple of Bluetooth screens, and the splash screen.

I have tried the '05 method of getting to the Override button, but those instructions appear to do nothing...
