Code B2482 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 valid signal on the keypad signal circuit for longer than 15 s. If one of the OnStar® buttons is held or stuck for 15 s or greater, the Telematics Communication Interface Control Module will set this DTC.
