Telematics Transceiver Malfunction (B15A8)
This DTC is stored when an error in EEPROM or PLL IC is detected during the DCM (Telematics Transceiver) self-check. The EEPROM (Electrically Erasable Programmable Read-Only Memory) stores the various data to operate Safety Connect. The PLL IC (Phase-Locked Loop Integrated Circuit) oscillates the telephone radio frequency.
