| Diagnosis and Testing Refer to Wiring Diagrams Section 413-01, for schematic and connector information. Principles of Operation The instrument cluster is a mix of intelligent and hardwired electrical signals and has a built-in self-test feature. The instrument cluster is connected to the powertrain control module (PCM), anti-lock brake system (ABS) and traction control (TC) (if equipped) by a control area network (CAN) bus. This link allows the instrument cluster and the PCM to communicate with each other. The instrument cluster consists of gauges, indicators and warning indicators. On the high series instrument cluster an information and message center is fitted. When the ignition switch is turned to position II from either position 0 or position I the instrument cluster carries out a display test to verify that the warning indicator or indicator bulbs and monitored systems are functioning correctly. The warning indicator or indicator bulbs which illuminate during this test are: - ABS
- Air bag system
- Charging system
- Brake system
- Low fuel
- Low oil pressure
- Malfunction indicator lamp (MIL)
- TC (if equipped)
- Glow plugs - vehicles with diesel engine
Configuration of Instrument Cluster The instrument cluster is a programmable module, which must be configured by selecting the Programmable Module Installation Routine on WDS. Inspection and Verification - Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage.

| - Verify the following systems are working correctly:
- Charging.
- Fuel delivery.
- Cooling.
- Turn signals.
- Headlamps.
If a particular system(s) is not working correctly, refer to the appropriate section of the workshop manual. - If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the concern is not visually evident, verify the symptom and enter Self-Diagnostic Mode.
Self-Diagnostic Mode - To select the instrument cluster self-diagnostic mode depress and hold the tripmeter reset button then turn the ignition switch to position II or III.
- Release the tripmeter reset button when TEST is displayed on the odometer Liquid Crystal Display (LCD). This will take between five and eight seconds.
- The instrument cluster will enter the gauge sweep test.
- To navigate to the following tests while in self diagnostic mode depress the RESET button to move to the next test.
- The self-diagnostic mode is deactivated when the ignition is turned to the position 0.
- If the self-diagnostic mode cannot be accessed, REFER to WDS.
