This procedure only applies to models equipped with premium Driver Information Center (DIC) switch.
- Perform INSTRUMENT CLUSTER SYSTEM CHECK under TROUBLE SHOOTING. Go to next step.
- Connect scan tool to Data Link Connector (DLC). Turn ignition switch to ON position. Using scan tool, check for Instrument Panel Cluster (IPC) DTCs. If scan tool displays any IPC DTCs, go to appropriate diagnostic procedure. See INSTRUMENT PANEL CLUSTER (IPC) DTC INDEX table under SELF-DIAGNOSTIC SYSTEM. If scan tool does not display any IPC DTC, go to next step.
- Using scan tool, select IPC INPUTS MENU. Monitor gauge input value on scan tool, while pressing GAUGE button on Driver Information Center (DIC) switch. If gauge input value on scan tool cycles on and off when GAUGE button is pressed, go to step 11 . If gauge input value does not cycle, go to next step.
- Turn ignition switch to OFF position. Disconnect IPC module 34-pin connector. Connect DVOM between IPC module connector terminal A9 (Red wire) and ground. While observing DVOM, press DIC switch GAUGE button. If reading is 5 ohms or less, go to next step. If reading is greater than 5 ohms, go to step 10 .
- Connect IPC module 34-pin connector. Turn ignition switch to ON position. Depress GAUGE button to cycle through gauge information on DIC display. If GAUGE button functions properly, go to next step. If GAUGE button does not function properly, go to step 8 .
- Turn ignition switch to OFF position. Check for open Red wire between Driver Information Center (DIC) switch terminal "C" and IPC module 34-pin connector terminal A9. See WIRING DIAGRAMS . If open exists in Red wire, go to next step. If open does not exist, go to step 8 .
