Circuit / System Description
The OnStar? button assembly consists of 3 buttons, Call/Answer, OnStar? Call Center, and OnStar? Emergency. The communication interface module (CIM) supplies the OnStar? button assembly with 10?V via the keypad supply voltage circuit . Each of the buttons, when pressed, completes the circuit across a resistor allowing a specific voltage to be returned to the CIM over the keypad signal circuit. Depending upon the voltage range returned, the CIM is able to identify which button has been activated.
