Swift SOHC
ECM is located under left side of dash. ECM distributes power to all sensors except oxygen and speed sensor, which generate their own voltage signal. ECM power is sent from EFI main relay to ECM terminal B1. ECM back-up power is received from 15-amp taillight fuse at ECM terminal A26.
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 the control unit.
