the 200 A fuse is one of the main fuses... there is also an E-box in the engine compartment, on the right side next to firewall, behind the windshield washer canister - that one mostly has relays but i think it also has a couple of fuses... they relate to the engine management...

one of the ways to "reset" the car is to disconnect the battery for at least half an hour, as there numerous countdown timers, the main shuts off the modules after 16 minutes but some also have additional a minute or two after the main sleep signal... when the battery is disconnected, you may touch the DISCONNECTED (+) lead to GROUND, it will ensure that there is same potential on both ends of the main leads... This procedure by itself does NOT reset anything, it is just a old practice from the electronic bench repairs, to reassure that there is no floating voltage or potentials in the system...

when you reconnect the battery, see if the all the original problems are still there, if there any new problems or if the problems shifted - old ones are gone, some new appeared...
these cars are way too sensitive to the voltages...
