VSC Off light comes and off under acceleration
I have spent the last few hours searching and can't find any answers related to my problem. Everything I find is related to check engine, VSC Trac, and VSC off light.
I purchased a used 2004 GX470 with 129k that is in great condition. Just recently I get the VSC Off light coming on and off when I accelerate. It usually happens when I accelerate going up a hill or accelerate harder. The light will come on for a few seconds and then turn off. No other lights or codes. I am not sure what direction to take with this problem. It seems like it wouldn't be related to the common gas cap problem? Maybe wheel sensors? Crawling under they look ok with no obvious problems. Any ideas?

I haven't seen this. Maybe get the codes read?

IMO this is supposed to be like that. If you are accelerating hard on gravel or any loose dirt mud or SNOW, ATRAC will kick in . You didn't mentioned but i assume that Traction Control Light also comes on and OFF with VSC. If it doesn't happen during normal driving i.e. Normal acceleration and doesn't stay ON all the time then you don't have nothing to worry about.

Can you explain a little what led up to this problem or it just started happening.
I would suggest try resetting the ECU and see if you get the same problem again.
Disconnect the negative terminal on the battery for 10 minutes and then re-connect. You'll have to initialize the power windows afterwards.
Hope it helps.

This problem is definitely unique.

I will try and reset the ECU. Could this also be something related to Zero Point calibration?

Do you still have the battery hold-down? Is it snug?

What condition are all of your tires in, tread depthness wise? I learned as this being my first 4 wheel drive, the tread needs to be matching or very close because everything turns in sync. Another thing you may want to do is, as someone already stated, check for soft codes. Another thought, ABS sensor? Picked up/was interfered with something to make it inermittently not communicate signal right. I seen cars that the sensors are in and working properly, took a plastic mallet and tap them very lightly and no more issue. Please ler us know what you find
