Circuit Operation

WARNING: This page is about a different car, the 2004 Mitsubishi Eclipse. However, it is still accessible from the selected car via links, so may be relevant.

This circuit judges the signals of each switch ("OFF," "SET," "RESUME," "CANCEL" and "MAIN") of the auto-cruise control switch. The auto-cruise control-ECU detects the state of the auto-cruise control switch by sensing the voltages shown below.

When all switches are OFF, the ECU detects 3.5 - 5.0 volts.
When the "SET" switch is ON, the ECU detects 0.4 - 2.3 volts.
When the "RESUME" switch is ON, the ECU detects 2.3 - 3.5 volts.
When the "CANCEL" switch is ON, the ECU detects 0.4 volts or less.
When the main switch is ON, the ECU detects 7.0 volts.
