Indicators are located in various locations within the Instrument Panel Cluster (IPC) and are all connected to the electronic circuit board. All of the indicators are completely controlled by the IPC. The various indicators are controlled by different strategies; some receive fused ignition output from the IPC circuitry and have a switched ground, while others are grounded through the IPC circuitry and have a switched battery feed. However, most are controlled by Control Area Network (CAN) or Local Interface Network (LIN) data bus messages from other electronic modules in the vehicle while others are controlled by a combination of hardwired inputs, electronic messaging and IPC programming. If the IPC loses CAN data bus communication, the IPC circuitry will automatically turn ON the Malfunction Indicator Lamp (MIL) until CAN data bus communication is restored.

In addition, certain indicators in this IPC are automatically or self-configured. This feature allows the configurable indicators to be enabled by the IPC circuitry for compatibility with certain optional equipment. These indicators are enabled or disabled by an electronic configuration message sent to the IPC by the Body Control Module (BCM). The BCM default for the Anti-lock Brake System (ABS) and the airbag indicators is enabled. The automatically or self-configured indicators remain latent in the IPC at all times and will be active only when the IPC receives the appropriate CAN or LIN bus message inputs for that optional system or equipment.

The hardwired indicator inputs may be diagnosed using conventional diagnostic tools and procedures. However, the IPC circuitry and electronic CAN or LIN data bus message controlled indicators are diagnosed using a diagnostic scan tool. Proper testing of the CAN or LIN data bus and the electronic data bus message inputs to the IPC that control each indicator requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information. Refer to DIAGNOSTIC CODE INDEX .
