Generator Idle Boost (LD9 Only)

The generator idle boost function (4 cylinder applications) provides a boost of engine RPM when multiple loads on the electrical system are present during engine idle. This is done to minimize the battery discharge and is accomplished by raising the engine idle RPM. Thus higher generator output is produced when the vehicle is idling. This function's operation can be calibrated OFF if needed.
