Using Scan Tool

  1. Connect scan tool to Data Link Connector (DLC), located under instrument panel, to retrieve continuous diagnostic trouble codes (DTCs) and run self-test diagnostics.
  2. If self-test is passed and no DTCs are retrieved, go to diagnostic symptoms table. See DIAGNOSTIC SYMPTOMS  table.
  3. If DTCs are retrieved, go to diagnostic trouble code identification table to continue diagnostics. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION  table.
  4. If RCM cannot be accessed by scan tool, go to TEST Y: NO COMMUNICATION WITH RCM  under DIAGNOSTIC TESTS  to continue diagnostics.
