Service bulletin TTT073723

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

TT: A very small percentage of customers experience operational difficulties with some telematics features which they cannot resolve on their own. These resources, in conjunction with the Repair Manual, are for dealership personnel to assist those customers with user issues, user errors, and compatibility issues with other vehicle systems and external applications encountered while operating telematics features. Toyota has developed and provided the following Telematics Diagnostic Guide to assist dealer technicians.
