Electronic Control Module (ECM)

The ECM is located under dash, behind passenger's side kick panel. ECM's main function is to ensure optimum engine performance. ECM uses signals received from driver's controls and various sensor inputs to control engine performance.

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