B1A82 LINCOLN Description

The message center functionality is controlled through the message center switch (part of the LH steering wheel switch), which is hardwired to the Instrument Panel Cluster (IPC) through input and return circuits. There are 3 message center switch buttons (base IPC ) or 5 message center switch buttons (optional IPC ). Each button operates a unique switch within the message center switch portion of the LH steering wheel switch assembly using a different resistance value associated with each specific button. The IPC sends out a reference voltage to the LH steering wheel switch on the input circuit and monitors the voltage drop when a message center switch button is pressed. The voltage drop varies depending upon the resistance of the specific button pressed, providing indication to the IPC , which switch is pressed.
