Anyone pulled their power steering fuse?

Why would this be the case? There are a few additional passive components that need to be added around the F/V and comparator, but it seems to be fairly straightforward. Is it a matter of getting a comparator that has enough hysteresis to prevent noise around the switching point from making the output fluctuate? Sorry if those aren't the right terms, I just looked some of this up.

I looked at the EWD and the power steering is already throttled by the ECU based on speed and the torque sensor. According to p 176 of the EWD:

* In order to reduce driver’s steering force, the assist current is calculated from the torque sensor signal and vehicle speed
signal of the meter or CAN communication to output to the motor.

∗ When abnormality occurs in the system, the assist is prohibited by shutting off the power source relay and motor relay in
ECU, and the warning light (P/S) in the meter is lit up.

So if we were to ever crack the ECU, we could in theory change the control algorithm. It seems strange that removing the fuse doesn't turn on the (P/S) light.
