i am working on 200D LC. the throttle is not working. it slid off into a creek. was in about 5ft of water. if you could show me a schematic of throttle. and what wires go where. that would really help me out. i have checked most of the connections i couldn't find anything. pulled them apart to check for water or corrosion but haven't found anything i havent took apart anything in the cab yet. serial number is 1FF200DXHA0512364.
The engine control unit is probably toasted. It is located behind the seat. That is where I would start, power to the ECU and any indicators that it may have.
Welcome to HEF blythe ! Not much to show. Turn throttle, varying voltage to the main controller, main controller sends throttle requirements to the ECU via the "CAN" network, ECU changes engine speed. Do you know how to access the Service Menu in the monitor? Throttle dial voltages can be read there. You can also access codes from there as well.
