DTC |
B15DB |
Telematics Transceiver Disconnected |
DESCRIPTION
If the radio and display receiver assembly cannot detect the DCM (telematics transceiver) for a certain period of time (90 seconds) after the ignition switch is turned to ACC and the radio and display receiver assembly confirms that the information is missing by checking past DCM (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.

CAUTION / NOTICE / HINT
NOTICE:
-
When replacing the radio and display receiver assembly, always replace it with a new one. If a radio and display receiver assembly which was installed to another vehicle is used, the following may occur:
- A communication malfunction DTC may be stored.
- The radio and display receiver assembly may not operate normally.
- 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.
-
Before replacing the DCM (telematics transceiver), refer to Registration.
