Circuit Operation

WARNING: This page is about a different car, the 2005 Mitsubishi Montero. However, it is still accessible from the selected car via links, so may be relevant.

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

When all switches are OFF: 4.7 - 5.3 volts
When the "MAIN" switch is ON: 0 - 0.3 volt
When the "SET" switch is ON: 2.1 - 2.7 volts
When the "RESUME" switch is ON: 3.3 - 4.0 volts
When the "CANCEL" switch is ON: 0.8 - 1.5 volts
