Auto-Cruise Control Switch
WARNING: This page is about a different car, the 2002 Mitsubishi Eclipse. However, it is still accessible from the selected car via links, so may be relevant.
Measure the resistance between the terminals when each of the "SET," "RESUME," "CANCEL" and "MAIN" switches is pressed. See Figure. If the values measured at the time correspond to those in the table below, the resistance values are correct.
