Instrument Cluster - Service Information: Description: Notes

The Instrument Cluster (IC) is used to inform the driver about important vehicle operating conditions and to warn the driver about potentially critical operating conditions. For this, the IC has indicator lamps, display gauges and audible tones. The IC's indicator lamps are displayed by text overlays that show the lamp's function. The information required for the indicator lamps and audible tones is transmitted from their sensors to the IC via direct lines or from their control modules to the IC via the Controller Area Network (CAN) data bus.

The IC has a microprocessor for analyzing the incoming data for the indicator lamps and audible tones. The program and the data required are stored in an electronic memory chip called the erasable electronic programmable read only memory (EEPROM).

The indicator lamps are listed below according to their type and actuation method (direct lines / CAN Bus).
