Control Unit
Electronic Control Unit (ECU) is located under center of dash, behind center console. See Fig 1 . ECU receives input voltage signals from a variety of input devices. The ECU compares each of the voltage input signals to a preset parameter which is programmed into the ECU. The ECU instantly analyzes each of the input voltage signals and adjusts output voltage signals accordingly. This allows for lower emissions while maintaining fuel economy and driveability.
NOTE:
Components are grouped into 2 categories. The first category covers INPUT DEVICES, which control or produce voltage signals monitored by the ECU. The second category covers OUTPUT SIGNALS, which are components controlled by the ECU.
