CELLULAR COMMUNICATION: SAFETY CONNECT SYSTEM: B15A8: Telematics Transceiver Malfunction
B15A8 - Telematics Transceiver Malfunction

DESCRIPTION

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.
