Lexus Gs400 VSC lights on/off - no response from throttle - getting the dreaded "limp mode" - any definitive fix?
JA: Do you happen to know the code? Have you tried to reset the computer?
Customer: Turned off car, wait 5 minutes, turn it back on - check engine goes away.
JA: What year is your GS300?

Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.

Have you hooked up a scan tool to see which codes are stored?

Hello again Chris here,

  • Sorry you were not pleased with my help.
  • What would you like to do regarding your question now.
  • This post is coming up on the 7 day mark where it times out. When a post times out, that means it's no longer on my active list (you reply and I may never know it.)

Thanks Chris

Instead of trying to resolve on our own, we had to bring it in to Lexus due to the danger of this recurrence. I'll close the question.
