Who knows? It might not suck.

The last time I "calibrated" a steering rack it involved a torch and a large ballpeen hammer.
I knew the steering was electric assist but damn I had no idea how much data it's control unit was dealing with.

That being said, I am at work now. I did see your thread and planned on digging a bit but it looks like @Tcoat beat me to delivering the bitter reality. Your dealer probably just fired up techstream against it and pulled those specific indicators. A compound failure is rare. If I was to believe the dealer's diagnosis, personally, I would dig further into the servo system looking for an intermittent open. Closed-loop servo systems can be notoriously difficult to troubleshoot but one might get lucky finding an intermittent loose connector.

Your choice is to either have the dealer do the work, or snag a copy of techstream and try swapping/calibrating a known good drive unit. This is one of those "if you have to ask..." situations.

edit: I don't think it's the motor. That's usually a hard failure.

@Tcoat @Ultramaroon so you both think the EPS motor replacement and return to the shop will ultimately not be the solution, correct?

Both of your understandings of these circuits are far beyond mine, so if this is self-evident then I'm embarrassed, but would the steering column replacement that they suggested negate all of the 30+ failure scenarios that you saw it could potential be, and be far enough into 'starting from scratch ' that the replacement of the entire column will likely resolve my issue completely? Or is it still somewhat likely to error after the steering column replacement?

Ok, I see this now. Like I said, I didn't have much time to read for full comprehension while working. If the dealer's diagnosis is to be believed AND the intermittent failure is with the encoder (motor position sensor), then, if that used EPS drive unit (not just the motor), is functional and you have the tools for calibration (techstream), you're on your way with the above hardware. Maybe not all that bad after all.

In auto parts stores, it's 3m molding tape.

In hardware stores, it's 3m extreme

Same stuff, main differences is the extreme comes in 1" width and up to 33' long, where the molding tape tends to be differing amounts under 1" wide, and never more than 5'-15' long per package.

Thinking of grabbing one for the balcony at my new apartment. I wouldn't be using it for camping.

That one looks like the old cabela's design, looks good. I got a cheaper version that likes to creap back until I'm inverted.

Get it. You'll like it.

As I said this is way beyond me as the cars I used to work on all the time only sensors were the driver.
From the looks of the manual there are at least 6 different sensors involved with the steering. Each of those sensors have between 2 and 6 possible failure modes. Add all the wiring, the control module and actual moving parts into the mix and an intermittent failure is almost impossible to identify through guess work.
To go back to what has been said I do not think you can diagnose this without capturing the failure codes with Techstream. There is just so much going on.

For example
"DESCRIPTION
The power steering ECU assembly receives vehicle speed signals from the skid control ECU via CAN communication. The power steering ECU assembly provides appropriate assisting force in accordance with the vehicle speed, based on the signals."
Your problem could be anyplace between a wheel speed sensor and the steering column. Even a loose or slightly corroded wire could be the issue. The only way to narrow it down would be to get the codes.

There was a big recall for the steering in Australia and all that was happening was that the position of some wires could cause small amounts of debris to create interference in the signal and the steering would cut out. No this does not apply to your car but that is how little it takes for the system to screw up. https://www.toyota.com.au/news/toyot...ted%20vehicles.

What I am confident in saying is that in all probability the motor is not the issue.

Now that you have everybody's attention we should probably take this discussion back to your failure tech thread so that if an answer is found it is not lost to posterity in the wastelands that are random thoughts.

Why would it go crazy now? Be moths away if at all.

Because, a lot of owner wanna change it back to stock to get the funds quickly before it comes out. When that happens, there will be a lot more ppl selling it.

At least that's how I see it. But I could be wrong

Oh and the flood of parts and cars will result in all the whining of "Why is my $5,000 turbo set up only worth $1,000 now. Damn lowballers" and "All of a sudden my car really dropped in value what a rip off"
