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
Tip:

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