Test Km: Step 17

17) Check For VPWR to Relay  With vehicle in Output State Check, disconnect harness from WAC relay and set DVOM on 20-volt scale. Measure voltage between VPWR circuit at the WAC relay vehicle harness connector and chassis ground. If voltage is greater than 10.5 volts, go to next step. If voltage is less than 10.5 volts, repair open circuit between power relay and WAC relay. Remove test equipment and retest system.
