*3: If the Electrical Load Signal display changes from OFF to ON, or the "Electric Load Feedback Val"
increases, it probably is a malfunction due to a change in electrical load. Check the generator and the
continuity and connections between the generator and ECM.
The normal value for the ISC learned value is engine displacement (liters) x 0.9.
