Someone hooked jumpers cables up backwards now the unit (8fgu25) Will crank and idle but has no gas pedal and no hydraulic function at all no horn and will go into foward and reverse but only at idle speed. No codes are showing just check engine light wrench light and seat sensor.
I've tried bypassing the seat sensor with same result checked all fuses that I could see everything looked good. Tried switching sas controller but did not fix the problem. Please help if you can thank you.
