Instrument Cluster - LHD: Notes

The Instrument Cluster is used to inform the driver of important vehicle operating conditions, and to warn the driver of potentially critical operating conditions. For this, the Instrument Cluster utilizes indicator lamps, display gauges and audible tones. The Instrument Cluster indicator lamps are displayed by text overlays that show the lamps function. The inputs to the Instrument Cluster are transmitted via hard wired sensors, or through the Controller Area Network (CAN) data bus.

The Instrument Cluster is equipped with a microprocessor designed to analyze 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 (hard wired or CAN Bus).
