I have a Cummins ISC engine, and I am getting an Engine Warning light. When I look at my diagnostics on the Silverleaf, it says ID 100 FMI 1 N1, Description "Low Oil Pressure". Yet when I monitor the oil pressure on the dash and on the Silverleaf, it shows between 32 and 36 punds, as it always has been. I keep getting the warning light, yet the oil pressure is good. Do you have any idea wht this means? Al Colby
