DTC B15A8: Telematics Transceiver Malfunction [08/2013 - ]: Description
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
This DTC is set when an error in the EEPROM or PLL IC is detected on the DCM (Telematics Transceiver) self-check. The EEPROM (Electrically Erasable Programmable Read-Only Memory) stores the various data to operate the safety connect system. The PLL IC (Phase-Locked Loop Integrated Circuit) oscillates telephone radio frequency.
