Electro/Mechanical Instrument Cluster (EMIC)

SMART CLUSTER FEATURES
The Electro/Mechanical Instrument Cluster (EMIC) houses the Fuel, Voltmeter, Engine Coolant Temp, and Oil Pressure gauges, the Speedometer and the Tachometer. The cluster positions the analog gauges using PCI Bus messages received from the PCM. The cluster also contains warning indicators as well as indicators for the Right and Left turn signals and the High Beam headlamps. Some of the indicators are hardwired to the cluster and some indicators are controlled by messages received on the PCI Bus. The vehicle Chime function, Courtesy Lamp Output, the Battery Saver function, and the Rear Window Defogger timer are contained internally within the cluster. The cluster contains a vacuum fluorescent (VF) display for the Odometer/ Trip function. The cluster VF will also display P-codes and vehicle status messages. The cluster has the ability to store DTCs, communicate on the PCI Bus, display engine information, and display certain inputs using the DRBIII(R). The cluster is also able to perform a manual self-test.

INSTRUMENT CLUSTER SELF TEST
The Instrument Cluster is capable of performing a diagnostic self test. The self test is actuated by depressing and holding the trip reset button while turning the ignition from the off to the on position. The self test can also be initiated using the DRBIII(R). The self test will terminate if the tachometer is greater than 300 RPM, the ignition is turned off, or the test is complete.
