DESCRIPTION These DTCs are
stored when the DCM (Telematics Transceiver) detects an open or a short
in the telephone and GPS antenna assembly (for Roof Side) circuit. The
DCM (Telematics Transceiver) receives 1574.42 - 1576.42 MHz radio
frequency signals from satellites through the telephone and GPS antenna
assembly (for Roof Side). The cable is a 50 Ω coaxial cable. |
