  3. Remove cruise control ECU with connector connected. See Figure. Turn ignition switch to ON position. Using voltmeter positive lead, backprobe cruise control ECU connector terminal No. 3 (Blue/Black wire) with negative lead to ground. With clutch pedal depressed, battery voltage should exist. With clutch pedal released, voltage should be less than one volt. If voltage is not as specified, go to next step. If voltage is as specified, no problem is indicated at this time.
