Hi,

I have a 2006 GS430. Occasionally, most of the light in the front panel would lighted up ( VSC, SKID, !, Check Engine, ect...). This is the second times it happened. The car run normal without any issue or problem. This is the second time it happened. The first time, I brought it to the dealer and fix it without providing much info on how. I don't think the dealer know how to fix this issue.

Any comment or suggestion will be much appreciated! Thanks!

Honestly, I would bring it to the dealer to have them check on any fault codes. Never happened to me.

Check the OBDII codes from AutoZone. I had the same problem after I installed my full intake system. Never figured it out so I sent the whole system back. Back to new.

You can always reset back disconnecting the negative battery terminal.
