Onan EC-AGS+ generator does not start in Auto Mode
The EC-AGS+ owner manual routes Auto Mode no-start checks through generator-set faults, accelerometer-fault alerts, temperature setting, quiet-time settings, and mobile-device clock settings before service-only diagnosis.
Owner-safe checklist
- Do not enable AGS indoors or in a confined space, and disable AGS before fueling, storage, servicing, or any CO/exhaust concern.
- Record whether Auto Mode is enabled, whether an Accelerometer Fault alert is active, the quiet-time window, and the mobile-device time zone.
- Check only normal app settings for temperature, quiet time, and clock/time-zone accuracy.
- If the app shows generator-set fault codes, treat them as generator faults and use Cummins Onan or qualified generator service.
