A Symptom Diagnosis

IMPORTANT:
1. Perform A Diagnostic System Check - Instrument Cluster before using the symptom tables in order to verify that all of the following are true:
^ There are no DTCs set.
^ The control module(s) can communicate via the class 2 serial data link.
2. Review the system operation in order to familiarize yourself with the system functions. Refer to Instrument Cluster Circuit Description.

Visual/physical Inspection
^ Inspect for aftermarket devices which could affect the operation of the instrument cluster or audible warnings system. Refer to Checking Aftermarket Accessories in Diagrams.
^ Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom.
^ For any indicators relating to fluid level, perform a visual inspection of the fluid level before beginning diagnosis.
^ Verify that the indicators work properly during the bulb check.

Intermittent
Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent and Poor Connections in Diagrams.
