Warning lights PCS, VSC, 4-LO

[HighMile200]

Has anyone seen this on startup?

I am getting this combination of warnings intermittently on start. If I stop and restart the ignition, it goes away. Toyota service stated they were unable to replicate and their flowcharts indicated need to replace the transfer case switch, but they could not produce a failure therefore didn't think there's a problem with the switch. They suspect a wiring issue since these are all associated with the ABS circuit, but could not trace down an issue there either.

Any similar experiences or recommendations?

I had the same issue but it was a pinched line. If I did this quote correctly you'll see a unit and the print out. Trace that unit down in your engine bay - and passenger front quarter panel. it's an air pump unit. find where it plugs into the car and unplug it - see if that makes the codes go away. Not going to hurt anything to try - I don't think. post up your findings
thank you

Here is the print out in full - do with it as you wish. May help may not - I'd like to know either way.
thanks

Ok here is a tip: Got those flashing lights???

Check your reverse light fuse.

Crazy I know. But true.
