NOTE: Perform SOLENOID CIRCUIT TEST  under ON-VEHICLE TESTING before testing starter relay.
  1. Remove starter relay from Power Distribution Center (PDC). PDC is located in engine compartment. Refer to PDC label for starter relay identification. Using DVOM, check for continuity between starter relay terminals No. 30 and 87. See Figure. If no continuity exists, replace starter relay. If no continuity exists, go to next step.
  2. Using DVOM, measure resistance between starter relay terminals No. 85 and 86. If resistance is not 70-80 ohms, replace starter relay. If resistance is 70-80 ohms, connect a 12-volt power source to starter relay terminals No. 85 and 86. Continuity should exist between starter relay terminals No. 30 and 87. Replace starter relay if it does not test as specified. If starter relay tests as specified, go to STARTER RELAY CIRCUIT TEST .
