Self-Diagnostic System: Notes

Instrument Panel Cluster (IPC) is equipped with a self-diagnostic system, which detects system Diagnostic Trouble Codes (DTC) or abnormalities. When a malfunction occurs, IPC will store a DTC. Malfunctions are recorded as history/intermittent failures or as current failures. Current DTCs indicate IPC has detected a fault which is currently present. A history DTC indicates that IPC has previously detected a malfunction that is not currently present as it is either an intermittent condition or the system is not being currently operated.

IPC is equipped with a 20-character vacuum fluorescent display feature identified as the Driver's Information Center (DIC) that can display specific warning/status messages. See DRIVER INFORMATION CENTER (DIC) WARNING MESSAGES  under OPERATION. These warning messages will be displayed in order of priority. If ignition is cycled, IPC will display last message before ignition was cycled. Many messages may coincide with warning indicator lights or DTCs. DTCs should always be diagnosed first before any warning message.

To retrieve stored DTCs, perform INSTRUMENT PANEL CLUSTER DIAGNOSTIC SYSTEM CHECK  . DIC can also be used to retrieve and clear DTCs. See USING ON-BOARD DIAGNOSTICS  .
