No Communication With All Systems

  1. Check voltage between ground and DLC terminal No. 16. If battery voltage does not exist, check junction connectors and wiring harness between DLC terminal No. 16 and power supply. If battery voltage exists, go to next step.
  2. Check continuity between ground and DLC terminal No. 4 and then between ground and DLC terminal No. 5. If continuity exists on both circuits, replace scan tool. If continuity is not as specified, check wiring harness between ground and DLC terminal 4 and/or 5.
