Anyone pulled their power steering fuse?

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:


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.

I just mean based on the overall number of components and the little bit of math required for configuring the comparator, etc.

The P/S light id turned on by the combination meter when the EPS reports an issue. If the EPS isn't alive it can't complain.

Understood. For an entry level EE student like me, the more cost effective solution would be using components and a breadboard instead of a PLD. Most of us DIY-ers don't have access to a programmer. The only microcontroller I've been exposed to so far comes on a $150 dev board, and that's a bit too expensive to cloister in a box under the dash. =)
