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 telematics 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 telematics system will not operate normally.

DTC Code DTC Detection Condition Trouble Area
B15DB Telematics transceiver disconnected

  • 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.

  • 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 - BATTERY AND BODY GROUND)


    1. Disconnect the N169 telematics transceiver connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      N169-4 (E) - Body ground Always Below 1 Ω

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      N169-1 (+B) - N169-4 (E) Power switch off 11 to 14 V
      N169-8 (ACC) - N169-4 (E) Power switch on (ACC) 11 to 14 V
      N169-7 (IG2) - N169-4 (E) Power switch on (IG) 11 to 14 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK MULTI-MEDIA MODULE RECEIVER ASSEMBLY

  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 N145 multi-media module receiver assembly connector.

    3. Disconnect the N146 telematics transceiver connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      N146-4 (USBV) - N145-4 (USBV) Always Below 1 Ω
      N146-2 (USBG) - N145-2 (USBG) Always Below 1 Ω
      N146-1-2 (USB+) - N145-1-2 (USB+) Always Below 1 Ω
      N146-1-1 (USB-) - N145-1-1 (USB-) Always Below 1 Ω
      N146-1-3 (USBS) - N145-1-3 (USBS) Always Below 1 Ω
      N146-4 (USBV) - Body ground Always 10 kΩ or higher
      N146-2 (USBG) - Body ground Always 10 kΩ or higher
      N146-1-2 (USB+) - Body ground Always 10 kΩ or higher
      N146-1-1 (USB-) - Body ground Always 10 kΩ or higher
      N146-1-3 (USBS) - Body ground Always 10 kΩ or higher

    NG
