Code B2470 Description

The cellular phone and navigation antenna are connected to the Telematics Communication Interface Control Module. This module supplies 5 V to the cellular phone and navigation antenna to power the internal amplifier. When the vehicle is equipped with the optional navigation radio, a navigation antenna signal splitter is installed to distribute the GPS signal to both the Telematics Communication Interface Control Module and the navigation radio. The navigation radio supplies 5 V through the GPS antenna coaxial cable to the navigation antenna signal splitter to power the internal navigation radio signal amplifier. The Diagnostic Trouble Code (DTC) will be set when the Telematics Communication Interface Control Module detects a failure in the cellular antenna signal circuit.
