Input Devices: Notes
NOTE:
Components are grouped into 2 categories. The first category is INPUT DEVICES , which control or produce voltage signals monitored by ECM called input signals. The second category is OUTPUT SIGNALS , which are components controlled by ECM.
Vehicles are equipped with different combinations of input devices. Not all devices may be used. To determine input usage on a specific model, see WIRING DIAGRAMS article. Available input signals include:
