Code B2476 2016 Chevrolet Silverado Description

The OnStar® button assembly consists of 3 buttons: Call/Answer, OnStar® Call Center, and OnStar® Emergency. The Telematics Communication Interface Control Module supplies the OnStar® button assembly with 10 V via the 10 V reference circuit. When pressed, each button completes the circuit across a resistor or set of resistors allowing a specific voltage to be returned to the Telematics Communication Interface Control Module over the signal circuit. Depending upon the voltage range returned, the Telematics Communication Interface Control Module is able to identify which button has been pressed. The Diagnostic Trouble Code (DTC) will be set when the Telematics Communication Interface Control Module detects a failure on the 10 V reference circuit.
