DTC B15C0: Short in GPS Antenna; DTC B15C1: Open in GPS Antenna [11/2018 - 10/2019]: Description

These DTCs are stored when the DCM (Telephone Transceiver Assembly) detects an open or a short in the telephone and GPS antenna assembly (No. 1 amplifier antenna assembly) circuit. The DCM (Telephone Transceiver Assembly) receives 1574.42 - 1576.42 MHz radio frequency signals from satellites through the telephone and GPS antenna assembly (No. 1 amplifier antenna assembly). The cable is a 50 Ω coaxial cable.
