Engine Control Module (ECM)

The service reset push-button is also used to obtain information about

active alarms. The Major and Minor alarm LEDs are very general and a

technician will need more detailed information upon arrival to the site of an

alarming ECM. To retrieve details about an active alarm, the user presses and

releases the service-reset switch. An active alarm (Major or Minor) will be

indicated by the LEDs as indicated in Figure 3-1. Note that depressing the

service-reset switch for 5 seconds will cause the service timer to clear

possibly disrupting the preventive maintenance schedule. When the service-

reset button is pressed again, the LEDs will represent the next active alarm.

Pressing the button when there are no more active alarms will reset the LEDs

to their normal usage. Several quick flashes of all five LEDs will indicate end of

the alarm list before the LEDs return to normal operation. If the service reset

button is not depressed again when an alarm is indicated, the LEDs will return

to normal operation after 30 seconds have elapsed. Resetting alarms via

status monitoring or via the manual stop switch will also clear the alarm

pattern indicated by the LEDs.
