Safety Connect System

CELLULAR COMMUNICATION: SAFETY CONNECT SYSTEM: B15C0, B15C1: Short in GPS Antenna
B15C1 - Open in GPS Antenna

DESCRIPTION

This DTC is set when the DCM (Telematics Transceiver) detects an open or a short in the telephone and GPS antenna circuit. The DCM (Telematics Transceiver) receives 1574.42 - 1576.42 MHz radio frequency signals from satellites through the telephone and GPS antenna assembly. The cable is a 50 Ohms coaxial cable.
