Test AE: Low Traction Indicator Inoperative: Testing
- If anti-lock brake system diagnostic system check has been performed, go to next step. If anti-lock brake system diagnostic system check has not been performed, see ANTI-LOCK BRAKE SYSTEM DIAGNOSTIC SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM in BODY CONTROL MODULES - AZTEK article.
- 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, select INSTRUMENT PANEL CLUSTER SPECIAL FUNCTIONS mode. Go to DISPLAYS TEST in OUTPUT CONTROL. Command all indicators on. If LOW TRAC indicator turns on and off as commanded, go to next step. If LOW TRAC indicator does not turn on and off as commanded, go to step 4.
- Replace Electronic Brake Control Module (EBCM). See ANTI-LOCK BRAKE SYSTEM MODULE under REMOVAL & INSTALLATION in BODY CONTROL MODULES - AZTEK article. After repairs are made, perform anti-lock brake system diagnostic system check. See ANTI-LOCK BRAKE SYSTEM DIAGNOSTIC SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM in BODY CONTROL MODULES - AZTEK article.
- Disconnect Instrument Panel Cluster (IPC) and connect a test light across appropriate power and ground terminals. See WIRING DIAGRAMS . If test light does not illuminate, repair open in power or ground circuit to IPC. If test light illuminates, check for poor, loose or corroded terminals in IPC harness connector. If no problem exists, replace IPC. See INSTRUMENT PANEL CLUSTER under REMOVAL & INSTALLATION. If problem exists, repair as necessary. After repairs are made, perform anti-lock brake diagnostic system check.
