Circuit Operation

This circuit judges the signals of each switch ("CRUISE ON/OFF", "CANCEL", "SET-" and "RES+") of the cruise control switch. The ECM detects the state of the cruise control switch by sensing the voltages shown below.

When all switches are released: 4.7 - 5.0 volts
When the "CRUISE ON/OFF" switch is pressed: 0 - 0.5 volt
When the "CANCEL" switch is pressed: 1.0 - 1.8 volts
When the "SET-" switch is pressed: 2.3 - 3.0 volts
When the "RES+" switch is pressed: 3.5 - 4.2 volts
