Using ohmmeter, check continuity between ground and terminals No. 4 and 5 on DLC. Continuity should exist. Repair as needed. Using voltmeter, measure voltage between ground and terminal No. 16 on DLC. Battery voltage should exist. If battery voltage is not present, inspect fuse No. 17 in Power Distribution Center (PDC). Replace as needed. If battery voltage is present, replace scan tool cable or scan tool as necessary.
