Connect negative lead of voltmeter to cruise control module connector C228 terminal No. 5 (Orange/Black wire) and positive lead to terminal No. 1 (Blue wire). Using a second voltmeter or ohmmeter connected to ground, measure voltage or resistance at cruise control module connector terminals as indicated. See Fig 1. If voltages or resistances are not as specified, check appropriate circuit and component. If circuit and component are okay, replace cruise control module.
