NAVIGATION SYSTEM, Diagnostic DTC:B15DB

DTC Code DTC Name
B15DB Telematics Transceiver Disconnected

DESCRIPTION

If the multi-media module 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 multi-media module 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

  • Wire harness or connector

  • Telematics transceiver

  • Multi-media module receiver assembly

Tech Tips

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

INSPECTION PROCEDURE

Note


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


    w/ G-BOOK System:

  • When replacing the multi-media module receiver assembly or telematics transceiver, perform vehicle contract setting (w/ Telematics Transceiver) Click here.

  • When replacing the multi-media module receiver assembly, perform vehicle contract setting (w/o Telematics Transceiver) Click here.

PROCEDURE


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


    1. Disconnect the G25 telematics transceiver connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G25-4 (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
      G25-1 (+B) - Body ground Power switch off 11 to 14 V
      G25-7 (IG2) - Body ground Power switch on (IG) 11 to 14 V
      G25-8 (ACC) - Body ground Power switch on (ACC) 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

    OK

  3. CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - TELEMATICS TRANSCEIVER)


    1. Check the installation condition.


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

    2. Disconnect the G47 multi-media module receiver assembly connector.

    3. Disconnect the G51 telematics transceiver connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G47-4 (USBV) - G51-4 (USBV) Always Below 1 Ω
      G47-2 (USBG) - G51-2 (USBG) Always Below 1 Ω
      G47-4 (USBV) - Body ground Always 10 kΩ or higher
      G47-2 (USBG) - Body ground Always 10 kΩ or higher
      Standard Resistance (USB Cable)
      Tester Connection Condition Specified Condition
      G47-1-2 (USB+) - G51-1-2 (USB+) Always Below 1 Ω
      G47-1-1 (USB-) - G51-1-1 (USB-) Always Below 1 Ω
      G47-1-3 (USBS) - G51-1-3 (USBS) Always Below 1 Ω
      G51-1-2 (USB+) - Body ground Always 10 kΩ or higher
      G51-1-1 (USB-) - Body ground Always 10 kΩ or higher
      G51-1-3 (USBS) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. REPLACE TELEMATICS TRANSCEIVER


    1. Replace the telematics transceiver with a known good one and check if the same DTC is output again Click here.


      1. Clear the DTCs Click here.

      2. Recheck for DTCs and check that no DTCs are output.

        OK
        No DTCs are output.

    NG
