Electronic Control Module (ECM)
ECM is located under left side of dash. ECM power is received from the EFI main relay at ECM terminals A1 and A2. ECM back-up power is received from main fuse at ECM terminal A16.
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 control unit. The second category is OUTPUT SIGNALS, which are components controlled by ECM.
