NAVIGATION SYSTEM, Diagnostic DTC:B15DB

DTC Code DTC Name
B15DB Telematics Transceiver Disconnected

DESCRIPTION

If the radio receiver assembly cannot detect the telematics transceiver for a certain period of time (15 seconds) after the power switch is turned on (ACC) and the radio receiver assembly confirms that the information is missing by checking past telematics transceiver recognition information (registered information), this DTC will be stored.

The G-BOOK System 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 G-BOOK System will not operate normally.

DTC No. DTC Detection Condition Trouble Area
B15DB Telematics transceiver disconnected

  • Harness or connector

  • Telematics transceiver

  • Radio receiver assembly

Tech Tips

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

Note


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

  • 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 Click here.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TELEMATICS TRANSCEIVER POWER SOURCE)


    1. Disconnect the H101 telematics transceiver connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      H101-4 (E) - Body ground Always Below 1 Ω

    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      H101-1 (+B) - H101-4 (E) Power switch off 11 to 14 V
      H101-8 (ACC) - H101-4 (E) Power switch on (ACC) 11 to 14 V
      H101-7 (IG2) - H101-4 (E) Power switch on (IG) 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. INSPECT RADIO RECEIVER ASSEMBLY


    1. Disconnect the H158 radio receiver assembly connector.

  3. CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - TELEMATICS TRANSCEIVER)


    1. Check the installation condition.


      1. Check the USB communication cable (digital communication cable) between the radio receiver assembly and telematics transceiver for any installation or connection problems.

    2. Disconnect the H158 radio receiver assembly connector.

    3. Disconnect the H159 telematics transceiver connector.

    4. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      H158-4 (USBV) - H159-4 (USBV) Always Below 1 Ω
      H158-2 (USBG) - H159-2 (USBG) Always Below 1 Ω
      H158-4 (USBV) - Body ground Always 10 kΩ or higher
      H158-2 (USBG) - Body ground Always 10 kΩ or higher
      Standard Resistance (USB Cable)
      Tester Connection Condition Specified Condition
      H158-1-2 (USB (USB+)) - H159-1-2 (USB (USB+)) Always Below 1 Ω
      H158-1-1 (USB (USB-)) - H159-1-1 (USB (USB-)) Always Below 1 Ω
      H158-1-3 (USB (USBS)) - H159-1-3 (USB (USBS)) Always Below 1 Ω
      H159-1-2 (USB (USB+)) - Body ground Always 10 kΩ or higher
      H159-1-1 (USB (USB-)) - Body ground Always 10 kΩ or higher
      H159-1-3 (USB (USBS)) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
