B15CB

CELLULAR COMMUNICATION: SAFETY CONNECT SYSTEM: B1573,B15CB: Short in Telephone Antenna Circuit
B15CB - Telematics Transceiver Antenna Disconnected

DESCRIPTION

This DTC is set 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.
