DTC B1573: Short in Telephone Antenna Circuit; DTC B15CB: Telematics Transceiver Antenna Disconnected [09/2014 - 11/2017]: Description

These DTCs are stored when the DCM (Telematics Transceiver) detects an open or a short in the telephone and GPS antenna assembly circuit. The DCM (Telematics Transceiver) oscillates and receives 824 - 894 MHz or 1850 - 1990 MHz radio-frequency through the telephone and GPS antenna assembly.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
