Electronic Control Module for an ADEM II engine
(1) ECM connector ("P2")
(2) Electronic Control Module (ECM)
(3) ECM connector ("P1") The engine uses an Electronic Control Module (ECM) that is based on a microprocessor. The ECM is mounted on the left rear side of the cylinder block.The inputs and the outputs to the control module are designed to withstand the short circuits to the battery voltage without damage to the control. The electronic engine control system has the following features that are designed into the system.
Resistance to radio frequency
Resistance to electromagnetic interferenceThe ECM power supply provides electrical power to all engine mounted sensors and actuators. Reverse voltage polarity protection and resistance to vehicle power system voltage swings or surges have been designed into the ECM. The ECM also monitors all input from the sensors. The ECM also provides the correct outputs in order to ensure desired engine operation.The wiring harness provides communication or signal paths to the various sensors. The ECM performs many functions. The ECM contains all of the engine performance information. The ECM contains all of the information for the emission certification. Several examples are listed: engine timing, air/fuel ratio and rated fuel position control maps.The ECM is programmed to run diagnostic tests in order to separate a fault to a specific circuit. Once a fault is detected, the fault can be displayed on a diagnostic lamp. A multimeter can be used to check most problems. The ECM will log most of the diagnostic codes that are generated during engine operation. The logged codes or the active codes can be read by an electronic service tool. Refer to the Troubleshooting manual for your engine.
