Circuit / System Description
The telematics button assembly on the inside rearview mirror assembly consists of 3?buttons, Information/End Call, Holden Assist and Emergency. Ten?volts is supplied to the button assembly on 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 telematics module on the keypad signal circuit. Depending upon the voltage range returned, the telematics module is able to identify which button has been pressed.
