Toyota dealer/ VCS- Maintenance required

They do that for legal reasons. Toyota doesn't want to get sued for NOT checking if a floor mat is "safely installed".

Same thing as McDonald's putting a warning label on a coffee that says "CONTENTS MAY BE HOT!"

It's silly but that is where you end up when you are a huge corporation that gets sued (or attempted) every 30 seconds

 

Burnish front and rear diffs?

 

I get it. I know that whole
toyota floor mat fiasco.

Just sounds funny to me.

 

alraedy tried that. no dice

 

Then your going to need the trouble codes to go further

 

u0126 is the only code

 

That's a no-comm code with the SAS; start by verifying power and ground to the module. Could be something as simple as corrosion on the connector.
