Circuit Operation

WARNING: This page is about a different variant/trim than selected.

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.
