Cummins-Onan QG i error code 6 (QG 2800i/2500i)
Low Oil Level. Low oil level has been detected by the oil level switch. The generator set will shut down. QG 2800i / 2500i LP (HGLAA) code table - NOT the HGJAA (0983-0501) or KY table; the same number carries a different meaning on those families and on the QG i DF family (see the '(QG i DF)' entries). All HGLAA fault codes shut the generator set down; the status indicator light in the control switch flashes the code.
What to check, and in what order, is in the app. A step-by-step flow walks this code with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
