Engine Control Module

The Engine Control Module (ECM) provides precise control of fuel and ignition. Each system has self-diagnostic capabilities. ECM is located in a 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.
