Hello All,

Wondering if anyone knows how to get into the diagnostics mode on a '04 GX?

greasemnky

diag mode for what

greasemnky

for pretty much anything you need a scan tool which hooks up through the obd connector under th drver's dash area

Try this:

This is how you enable diagnostic mode, just turn off the car to get out of this mode
-Start car, turn on parking light
-Hold down both Climate and Audio buttons at the sametime do the next step
-Turn OFF parking light, then ON, then OFF, then ON, then OFF


You should see the service menu. Good Luck.

How in the hang did you figure this out. LOL

It was in another thread a while ago. I tried it and it works on the Rx470. It does not however give you the same menu functions that enable you to override anything. You can just go through some diagnostics.

What sorts of things can you diagnose in this menu???

That's how I figured out I need a new head unit!

It can tell you if something is wrong with the Audio Head Unit, Amp, the backup camera, and a lot more. It is also a way to watch the backup camera while driving forward as if to watch a trailer in tow.

I see, thanks Yaro.

stl2chi

does this work in the 2005? Watching the backup camera while driving would be very helpful

Yaro1,

I tried this a couple of times and was unable to see the camera image when in this mode. Do you have to do something special?

Thanks!

On my '04 GX it works. However, on my father's '05 RX all I see is gray when I go into RV cam Diag mode.

I think it might have to do with the generation of nav. Since the '05 GX and '05 RX have relatively the same nav, then if your GX is '05 that might be the cause. I didn't work much to figure out how to get it to work on '05 though. Is yours '05?

(EDIT: I checked your profile, yep it is an '05. Thats the cause then. I don't know how to work it ('05) yet though. Sorry.)

BY THE WAY:
A simpler way to get into the diag mode is this:

A. From almost any screen, press the "Display" button. A new frame pops up with settings.

B. Touch the top-left of the screen just below the frame, bottom left just above the frame. (repeat B two more times) Check out my stinky text-drawing interpretation below.

THE END

IE.
If this is the screen and the extra lines in the middle represent the framing, you would press where the numbers are in that order (except always touch where he numeber 1 is and 2 is, don't press out further to the right how it is show[ALWAYS STAY IN THE CORNER]).
