There is no standard OBD-II diagnostic trouble code (DTC) as "35". OBD-II codes are generally three or four digits. A code "35" might exist in a manufacturer-specific system (not the standardized OBD-II system), and its meaning would depend entirely on the specific vehicle make and model.
If you have a check engine light and a code "35" displayed, you must consult your vehicle's repair manual or a professional mechanic. They will be able to interpret the code within the context of your car's system.
