Pin Voltage Chart
Use pin voltage chart to pinpoint a malfunctioning circuit. See CRUISE CONTROL MODULE PIN VOLTAGE CHART. Test circuit voltages by backprobing Cruise Control Module (CCM) harness connector with a DVOM. See Fig 1 . All voltage tests are made with Black lead of DVOM grounded and ignition switch in ON position. Voltages may vary slightly from specification, but a variance of 5 volts or more definitely indicates a circuit problem.
