Background: Due to my work, I have been messing around a lot lately with Lexus and Toyota Navigation stereos systems and have been entering into the hidden for diagnostics of these stereos. These steps to enter in no matter year/generation of the stereo were very similar. So I was curious if I could apply these same steps on my own Lexus vehicle to see if I can access this Diagnostic menu as well. I tried a couple of different buttons until I was able to fall into the Hidden Menu.

Here I am sharing with all you how to enter this Menu should you ever need to in the future in case something actually should something in the system network stop working in your own vehicle

Steps to enter into the Hidden Navigation Diagnostic Menu
1. Press and Hold the "MENU" button
2. While still holding the "MENU" Button, Cycle the "Parking Light" Switch ON then OFF
3. Cycle the "Parking Light" Switch ON then OFF three more times.
4. Once you see the Menu appear you can let go of the "MENU" button



This should probably work on Other Lexus Navigation of the same era as well. GEN8

*Enter this Menu at your own discretion. I am not liable for you messing with things in here and bricking your Navigation stereo.

Thank you for your attention

 

Awesome!

Works on non nav units too!!!

 

Awesome! This is great.

 

Great job! Can't wait to try it tonight

 

With the car on, I hold the menu button and toggle between the top two light icons, but can't get the service menue. What am I doing wrong?

 

Toggle from DRL OFF to Second one from the top

 

This is awesome! Thanks for sharing! Going to test it out later

 

What can be controlled going into this menu on my 2015 Lexus Rx 350?

 

This is great! Thank you!

 

I wonder if disabling the diagnostics recording would mess up the enform subscription or something? Kind of interesting....

 

watch the video.....

 

In case anyone with an older model finds themselves here, I was able to do this on my 2007 RX350 by holding the INFO button and cycling the lights.

 

Nothing its for Lexus technician use.
