100% completely disable AWD/ECS/TCS removing fuse

[OmaHahn]

So..... I was adding the courtesy light feature to my LED DRLs and accidentally removed the wrong fuse. When I started the car a warning light and message popped up saying something to the affect the entire AWD system is disabled, etc. But the car started and drove just fine! I wonder if what I did is the same thing as shutting off ECS / TCS with the button on my center console? I have the PP option. OR...... I wonder if it does "more," than just using the button to disable ECS/TCS....?? Anyone know?

I remember watching a video where someone removed a fuse on a Tesla and it completely turned off AWD and became a REAR-WHEEL drive and he was doing major burn-outs in a parking lot! It's on YouTube! I wonder if removing this fuse does the same thing??!!

If the AWD system was disabled I would venture to guess the rear drive clutch packs wouldn't engage and you would be FWD only. Not really what you want!

What are your thoughts on the Tesla? That's AWD and the guy removed the fuse and became RWD. I'm guessing since it's a completely different type of vehicle with ALL 4 wheels being independently driven by electric motors, somehow this fuse turned off the front wheels....??

I don't think that's meant to be a long-term solution. Maybe for impressing people with burnouts at the track, but not good for much else. In fact, we don't know if having the AWD disengaged (SHO or Tesla) can end up damaging the drivetrain. Depends on the logic & design, I guess. Def not good for the SHO/PTU.

Depends which model tesla but the AWD version has separate AC motors driving the front and rear wheels with no mechanical linkage. They are all electronically controlled. So in theory pulling a fuse could disable the front motor and let the car be rear wheel drive but you would be running on "half power" so to speak so I don't see the point I'm not sure how crazy the electronics would be about it either so it may not even let you but if that guy did it then I suppose there is a scenario under which it is allowed.

I would think the fuse would just control the rear differential. Shouldn't really have any effect on the ptu. The drive shaft is spinning all the time regardless if the rear diff is engaged or not. Trust me, the car goes nowhere in fwd... The Awd is a blessing

This actually interesting for people that want to run drag radials. I've heard a few people say you only need them on the front but there is no way to really get them heated up. If you could put it on a switch you could do a fwd burn out to get them warm.
