Test W: Change Engine Oil Indicator Inoperative

  1. If instrument panel cluster diagnostic system check has been performed, go to next step. If instrument panel cluster diagnostic system check has not been performed, go to INSTRUMENT PANEL CLUSTER DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM.
  2. Connect scan tool to Data Link Connector (DLC). DLC is located under left side of instrument panel. Turn ignition switch to RUN position. Using scan tool, observe ENGINE OIL LIFE PERCENT in Powertrain Control Module (PCM) data 2 list. If scan tool displays zero percent with CHANGE ENGINE OIL message inoperative, go to next step. If scan tool displays zero percent with CHANGE ENGINE OIL message off, system is okay.
