The EMCP 3 GSC has the ability to reset all events for electronic engines with no J1939 support by means of a relay output. A number of conditions must be satisfied in order for this to work. FIRST:
SECOND: THIRD:
One of the Digital Selectors must be configured for ECU FAULT RESET. Refer to Digital Selector Options, in Chapter 10.1 for a list of options for Digital Selectors. The corresponding relay output must be wired to a corresponding Fault Reset I/O pin on the engine ECM or it must be setup to power cycle the ECM. The EMCP 3 GSC setpoints given in the table above must be set properly. Engine Type Configuration must be set to ELECTRONIC and Engine Control J1939 Data Link Support must be set to NO J1939 SUPPORT. In that case, the Engine Control will not be listed in the EMCP 3 GSC display event log. However, there will be an option to RESET ALL ENGINE EVENTS. with this option selected will activate the ECU Pressing the ENTER KEY FAULT RESET, which will activate the corresponding relay output and trigger the engine ECU to reset its faults or will power cycle the ECU.

TROUBLESHOOTING RESETTING EVENTS
There are common reasons for the EMCP 3 GSC not allowing events to be reset. First of all, in order to reset any event, the EMCP 3 GSC must be in STOP mode. In order to reset engine ECM events, the engine speed must also be zero. One common confusion about events is the SERVICE MAINTENANCE INTERVAL WARNING. This event is explained in the following Chapter. NOT IN AUTO Another event that can cause confusion is NOT IN AUTO. This event is Present whenever the control is in either RUN or STOP. As a result, it can not be reset in STOP (as the event is present). The event will reset when the control is returned to AUTO
.
If Event Warning Condition Response Auto Reset Enable Status is set to Disabled (so that warning events do not auto-reset) and the event response configuration for NOT IN AUTO is set to a Warning then it will not be possible to reset the NOT IN AUTO event. It will be Active when the control is in Auto and Present when the control is in STOP. If it is a requirement for Event Warning Condition Response Auto Reset Enable Status to be Disabled then it is strongly recommended to make the event response configuration of Not in Auto ACTIVE ONLY rather than Warning.
