No Communication With All Systems

  1. Check voltage between ground and Data Link Connector (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 does not exists on either circuit, check wiring harness between ground and DLC terminal No. 4 and/or 5.
