    With your cruise switch off, hold the resume switch down I think for a few seconds and let go and it will flash your engine light. For instance if it flashes five times and then a pause and flashes another five times that means all systems are normal. That is for a cat engine anyways not sure if other engines makes. Hope that helps.
