COMPONENTS FOR SYSTEM CONTROL

ENGINE CONTROL MODULE (ECM)

The ECM sends signals to control the actuators based on the information inputs from each sensor / switch. Major controls are as follows:

NAME AND CONTROL DESCRIPTION

1. Fuel injection control • Controls fuel injection amount and timing.

2. Ignition control • Controls ignition timing.

3. Idle air control • Controls idling/trolling speed by adjusting intake air amount through IAC valve.

4. Fuel pump control • Controls high pressure fuel pump drive.

5. Caution system control • Informs operator of abnormal engine condition. • Controls engine speed.

6. Self-diagnostic system control • Informs operator of sensor / switch malfunction.

7. Fail-safe system control • Allows operation during sensor/ switch malfunction.

8. Operating hour indication system control • Informs operator of total operating time in units of 50 hours.

9. Start-in-gear protection system control • Prevents engine start when shift is positioned in forward or reverse.

10. O2 feedback system control • Controls and performs O2 feedback operation using optional O2 sensor.

NOTE: The information related to the Caution system, Self-Diagnostic System, Operating hour indication system and O2 feedback system are retained in ECM memory.
