Diagnostic Starting Point - Instrument Panel, Gages and Console

Begin the IPC system diagnosis with the Diagnostic System Check - Instrument Cluster  and the Diagnostic System Check - Driver Information Systems . The Diagnostic System Check will provide the following information:

• The identification of the control modules which command the system.
• The ability of the control modules to communicate through the serial data circuit.
• The identification of any stored diagnostic trouble codes (DTCs) and their status.

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.

Begin the audible warning, DIC, and HUD system diagnosis by reviewing the system operation. Reviewing the operation information will help you determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the operation information will also help you determine if the condition described by the customer is normal operation. Refer to Symptoms - Instrument Panel, Gages and Console  in order to identify the correct procedure for diagnosing the audible warning, DIC, and HUD systems and where the procedure is located.
