NAVIGATION SYSTEM, Diagnostic DTC:B15DB

DTC Code DTC Name
B15DB Telematics Transceiver Disconnected

DESCRIPTION

If the radio receiver assembly cannot detect the DCM (telematics transceiver) for a certain period of time (90 seconds) after the engine switch is turned on (ACC) and the radio receiver assembly confirms that the information is missing by checking past DCM (telematics transceiver) recognition information (registered information), this DTC will be stored.

Tech Tips

The telematics system (w/ telematics transceiver for G-BOOK) uses USB communication between devices. If an open, short, short to +B or short to ground occurs in the USB circuit, communication is interrupted and the telematics system (w/ telematics transceiver for G-BOOK) will not operate normally.

DTC No. Detection Item DTC Detection Condition Trouble Area
B15DB Telematics Transceiver Disconnected DCM (telematics transceiver) disconnected

  • Harness or connector

  • DCM (telematics transceiver)

  • Radio receiver assembly

  • Navigation ECU

Tech Tips

This DTC may be stored due to environmental reasons such as electrical noise or interference.

CAUTION / NOTICE / HINT

Note


  • Inspect the fuses for circuits related to this system before performing the following procedure.

  • When replacing the DCM (telematics transceiver), make sure to replace it with a new one.

  • When replacing the radio receiver assembly or navigation ECU, always replace it with a new one.

    If a radio receiver assembly or navigation ECU which was installed to another vehicle is used, the following may occur:


    • A communication malfunction DTC may be stored.

    • The radio receiver assembly or navigation ECU may not operate normally.

Tech Tips

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Navigation System.
