I have a 2007 GS350 and all of the lights (Check 4WD, Check VSC, Brake, Engine Warning, etc.) are on.
I bought a scanner, hooked it up and it came back with no codes. I know the scanner is working because it came back with the correct VIN, but no codes at all. From reading this thread and elsewhere, I'm thinking it is either a fuse (how to tell which fuse) or something with the battery? Can't figure out what else it could be since the reader is coming back with no codes. Also want to make sure it is safe to drive since there are no actual codes flipped. The fact that the Brake (emer brake) light is on too makes me believe it's something electrical. Battery is less than a year old from Autozone.
Any other ideas or something I'm missing?

So my GS350 mentioned above with all the lights (brake, VSC, 4WD, CEL, etc.) - the battery tested out ok but alternator tested bad.
We had the alternator replaced but all the lights are still coming on. Taking it to the dealer tomorrow, but anything else I should check before taking it in? It's still coming back with no codes reported on the scanner.
The following post can go in multiple threads but I'll post it here and post a link in other threads if needed.
Ok, so my alternator died and I got it replaced. A few days after that, my car would jerk when shifting from 5th to 6th gear. I thought it was transmission but after researching here I decided do a ECU reset. I know I pulled and put the fuse back in correctly. However, after this, I had several issues.
1. VSC light is on with CHECK VSC message.
2. Remote won't unlock the door.
3. The unlock button on the door won't work.
4. Door lights won't come on.
5. cabin lights won't come on.
6. AFS light blinks constantly.
# 2 - #5 works fine once I start the car though.
My question...what may have I inadvertently done wrong while trying to reset ECU? How come so many things stopped working all of a sudden?
By the way, the issue with my transmission stuttering between 5th and 6th gear is still there. If this turns out to be transmission issue, I would dump the car and get a new one, however, I want the lights gone otherwise dealer won't pay anything for it. I just got new tires, batteries and alternater so I have quite a bit invested in the car already but I am willing to cut my losses if it is transmission.
I have been dealing with the check engine and vsc light for about 1 year on my 2006 gs awd.
Here's my story about how I eventually got it fixed. The first thing was the gas cap which is usually never the problem just a quick fix and a reset. After doing this the light came back on so I took it to another mechanic. He told me after inspecting the car their where no leaks in the exhaust and the O2 sensors seemed ok as well. The mechanic then suggested a $2200 cat convertor replacement. I was not happy to hear this. I did not go through with the repair and continued to drive for 6 months.
Eventually I started hearing a leak in the exhaust so I took to a professional muffler and exhaust place. They notices the leak in 2 minutes and swapped the pipe that was leaking. Finally the vsc light turned off after 2 weeks and has not returned in a week. Before it would turn off once I a while but return within a day. Would suggest that talking your gs to a professional muffler and exhaust place. He even gave me a way better qoute to change the cats if iI had too around 1000 bucks which seems reasonable thank god it looks good for now
