Engine Control Module
Engine Control Module (ECM) provides precise control of fuel, ignition and turbo operation (if equipped). Each system has self-diagnostic capabilities. ECM is located in box, on right side of engine compartment.
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.
