Engine Control Module
The Engine Control Module (ECM) consists of a microcomputer, connectors and wiring for voltage signal input/output and power supply. The unit is not serviceable and should not be opened. The ECM contains memory and logic circuits, enabling it to interpret sensor inputs and control various engine systems. To locate ECM, see ECM LOCATIONS table.

NOTE:
Components are grouped into 2 categories. The first category is INPUT DEVICES , which are components that control or produce voltage signals monitored by the ECM. The second category is OUTPUT SIGNALS , which are components controlled by the ECM.
