Christmas tree?
Hello I have a 2007 IS250 the dash has decided to light up like a Christmas 🎄! I have a red ∆ with ! In the middle,trac light, vcs, and break light. I've tried rest computer by ground removel for 10mins tested fuses- all good. Car runs fine though! I seen where it was a relay in blog few minutes ago. I will check them tomorrow, but does anyone have any other ideas,? I also checked voltage output from alternator which was at 14.67 or there about. Thank you for your time and ideas.

Search this forum and pray you don't have to pay 2K for an accumulator like I did for my LS.

My 2008 with 160K set off all of the lights you mentioned simply because of gunk build up . A local shop simply "cleaned it" and sent me on my merry way.
I will say the vehicle was suffering a less than smooth as usual idle AND a bit of irregular/ jerky response to the throttle. I did not drive it far, maybe 12 miles before the shop was able to take a look at her.
My guess is 14 years of sucking gas fumes builds up deposits that can cause your car to throw all those lights.
Good luck & let us know how your situation resolves.

Get a scan tool to read the codes. Preferably one with ABS capability. Sound like it's ABS related.
Reading codes is probably the best thing you can do. Rather then quessing the million reasons something could be wrong.
At what time did you check voltage? On a cold start? That typically is normal for a cold start then dwindle down to about 13.5V at idle.

I second this ^^ stop at a shop and get the codes read. There is no other sensible way to move forward.
Likely just low on blinker fluid! lol
