Test L: Tire Pressure Gauge Inoperative

  1. If IPC diagnostic system check was performed, go to next step. If IPC diagnostic system check was not performed, go to INSTRUMENT PANEL CLUSTER DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM. After performing IPC diagnostic system check, go to next step.
  2. Connect scan tool to Data Link Connector (DLC). Test drive vehicle greater than 25 MPH for 20 minutes or until tire pressure data is received. Using scan tool, select RFA data list and monitor TIRE PRESSURE. Scan tool will display 148 psi (1020 kPa) until tire pressure data is received. After tire pressure is received, tire pressure should be 0-62 psi (0-427 kPa). If tire pressure is as specified, go to next step. If tire pressure is not as specified, go to TIRE PRESSURE MONITORING DIAGNOSTIC SYSTEM CHECK in BODY CONTROL MODULES - CORVETTE article.
  3. Compare readings on scan tool with readings displayed on Driver's Information Center (DIC). If scan tool and DIC are within 5 psi (34 kPa), system is okay at this time. If scan tool and DIC are not within 5 psi (34 kPa), go to next step.
  4. Replace IPC. See INSTRUMENT PANEL CLUSTER  under REMOVAL & INSTALLATION. After repairs, go to next step.
  5. Recheck system operation to verify the repair. If system operates properly, repair is complete. If system does not operate properly, go to step  2 .
