Many modern vehicles hide service menus that most owners never know exist, and Toyota is no exception. According to one Toyota technician, newer models include a hidden diagnostics screen that can be accessed with a specific sequence of taps and swipes on the infotainment display.
The feature recently gained attention after Toyota technician Cam, who posts as @mdttoyotech on TikTok, demonstrated how to open the menu in a short video. While it isn’t intended for everyday use, the screen gives technicians access to a variety of diagnostic tools built into the vehicle’s infotainment system.
The video has sparked plenty of discussion among Toyota owners, with some successfully accessing the hidden menu while others struggled to get the sequence to work.
Although the feature may be tempting to explore, the technician behind the video says owners should think twice before changing any settings they don’t fully understand.
How To Access The Hidden Menu

According to Cam, older Toyota infotainment systems required users to hold down the audio button while repeatedly turning the headlights on and off to access the diagnostic menu.
Newer systems use a different process. After turning on the infotainment display, the screen must first be switched off using the Display menu. Once the display is dark, users perform a series of swipe gestures across the screen.
In the demonstration, the first vehicle failed to open the menu despite following the correct steps. Using a second Toyota, however, the process worked, with the system beeping after each swipe before revealing the hidden diagnostics screen.
What The Secret Screen Can Do
The diagnostics menu is designed primarily for troubleshooting infotainment-related issues rather than adding hidden features.
Once inside, technicians can check the touchscreen, microphone, backup camera, sensors, service information, production data, and other system functions that help diagnose problems with the vehicle’s multimedia system.
The menu can also display diagnostic information that may assist technicians when tracking down faults within the infotainment system.
Owners Say It Doesn’t Always Work
The comments on the video quickly filled with Toyota owners and dealership technicians sharing their own experiences. Several people said the process can be frustratingly inconsistent, with some explaining they’ve spent several minutes trying to access the menu before it finally appeared. Others noted the system won’t always respond if certain dealership diagnostic tools are connected to the vehicle.
A number of commenters also pointed out that the vehicle’s audio must be completely powered off rather than simply muted. Others recommended making full edge-to-edge swipe gestures across the display, saying shorter swipes often fail to trigger the menu.
Leave The Settings Alone Unless You Know What You’re Doing
While the hidden screen may seem like an opportunity to unlock extra features, Cam says it wasn’t designed for casual users.
According to the Toyota technician, the menu exists primarily as a diagnostic tool for trained technicians working on the infotainment system. Changing settings without understanding their purpose could potentially create new problems or alter system functions unintentionally.
For most owners, it’s an interesting hidden feature to know exists, but one that’s best left alone unless you’re diagnosing an issue or know exactly what each setting does.
Did you know your Toyota might have a hidden diagnostics screen? Have you ever discovered a secret menu or hidden feature in your own vehicle that most owners don’t know about?
