2021-2024 Toyota Multimedia Recorder (MMR) Data Download

Symptoms Requiring MMR Data Download

This Toyota Tech Tip, T-TT-0780-25, addresses various audio and telematics concerns in 2021-2024 Toyota vehicles. Technicians may need to perform a Toyota MMR data download from the head unit to investigate issues such as problems with Apple CarPlay, Android Auto, or Bluetooth connectivity. Other symptoms that might necessitate a Toyota MMR data download include the head unit rebooting, screen malfunctions, general connectivity problems, communication errors, or issues with system settings.

Diagnosis and Trigger Conditions

The Multimedia Recorder (MMR) data is a crucial tool for quality investigation, helping with the early detection and resolution of audio-related concerns. For specific issues like Apple CarPlay, Android Auto, or Bluetooth problems, the MMR data should ideally be pulled within approximately five minutes of the concern being duplicated. This timing is critical to ensure that relevant logs are saved in the head unit's internal memory and not overwritten. For other concerns, such as rebooting or screen issues, MMR logs may remain relevant for up to five days of average driving, depending on usage habits.

Important Warnings for Owners

Owners should be aware of several critical points regarding the Multimedia Recorder (MMR) data:

• If you have just experienced a concern and the ignition has not been switched off, you will need to cycle the key off and back on one time in a safe location before attempting to retrieve the MMR data.
• If the volume/power knob has been used to restart the head unit, any MMR data related to the concern will be lost. Therefore, do not restart the head unit if you are trying to capture MMR data for a concern.
• If a concern has been experienced, make sure to record the date and time of the occurrence and provide this information to your technician along with the MMR data.
• Please DO NOT attach MMR data to DPR/FTR (Dealer Product Report/Field Technical Report) if you are a technician; it should be uploaded to a TAS case or shared with FTS to be uploaded to OneDrive.

Multimedia Recorder (MMR) Data Download Procedure Summary

The process for performing a Toyota MMR data download involves several steps, primarily executed by a technician. First, with the ignition on and the vehicle stopped in a safe location, the technician will press and hold the “MENU” button on the faceplate while cycling the headlight switch from off to on three times. Alternatively, a GTS+ diagnostic tool can be used to navigate to the Diagnostic Mode through the Body Electrical, Navigation System, and Utility menus. Once in the Service Menu, the technician selects “Failure Diagnosis” and then “Diagnosis Recorder.”

The “Recording ON/OFF” function must be deselected (changing from green to white/grey). A hidden button is then pressed and held for up to 30 seconds. A blank 4GB to 32GB USB drive, formatted to FAT32, is inserted into the vehicle's USB port. The “output” button is pressed and held for up to 10 seconds, followed by selecting “Yes” and then “OK” on subsequent pop-up screens. After waiting for the files to copy to the USB drive, the technician selects “OK” again. Finally, the “BACK” button is pressed, and “Recording ON/OFF” is turned back to the ON position. The ignition is then turned off, and the USB drive is removed once its light turns off. The collected MMR data, typically a file named 17DISP_DREC.zip, is then confirmed and shared with the appropriate Toyota technical support channels.

Required Tools or Parts

To perform the Toyota MMR data download, technicians will need the following:

• An empty USB flash drive with a capacity between 4GB and 32GB.
• The USB drive must be formatted to FAT32.
• A GTS+ diagnostic tool may be used as an alternative method to access the diagnostic menu.

Owner Action

If your 2021-2024 Toyota vehicle is experiencing audio-related concerns, such as issues with Apple CarPlay, Android Auto, Bluetooth connectivity, or the head unit rebooting, it is recommended to visit an authorized Toyota dealership. Inform your service advisor about the specific symptoms and the date and time of occurrence. The dealership technicians are equipped to perform the Toyota MMR data download as outlined in Tech Tip T-TT-0780-25 to assist in diagnosing the problem.
