One more question - When you were getting this problem, did it only happen once in a while, or was it on full-time?

Thanks.

When I installed my HID, I disconnect the air filter box and when I reconnected it and started my car, the check VSC light was on. I disconnected the battery, press the brakes 10 times and reconnected the battery and the check VSC light was gone. I don't know if that was the normal procedure for that but my friend told me to do it and it worked.

It was very intermittent just like you describe with no ryhme or reason it would just turn on and if I shut the car off the lights would go off when restarted. I also did not notice any change in performance when the lights came on while driving. Let me know if you have other questions.

Well since you offered:

1.) I looked up that part number, it is a Stop Lamp Switch Assy. Do you know where the dealership did the work on your car? Was it somewhere along the steering column or near the brake pedal assembly?

2.) Your problem seems to be exactly the same as mine. Such a weird issue! Anyway, you said since the dealership replaced that part, you haven't had the problem again...so, how long ago did they do the fix for you?

Really appreciate the info. Some of these issues get ridiculously frustrating on such a nice car.

Thanks.

haha i know, it's such a weird thing to happen. Everything seems fine except the indicator lights come up and you don't have abs or trac if you were to need it.

For mine, all I have to do is pull over, turn the car off, turn it back on and thats it! Everything clears and I am back on my way.

My salvaged IS had all the same warning lights except for the BRAKE. One of the ABS sensors (aka wheel speed sensor) was ripped off, as soon as I replaced it, all the lights disappeared.

My warning lights were always on, and not intermittent like yours. The fact that your issue is intermittent, makes it very weird.

Sorry was out of town a couple days....
1. I am really not sure where they did the work, I did not ask too many questions when I heard the price I was expecting some crazy $500 plus estimate to fix.
2. I had it done about 4 months ago and no light has come on since....yeah it is really weird, it drove me nuts thats why I finally broke down and went to the dealership.
Good luck hope it is the same issue so you can get it fixed pretty cheap even at the stealership!!!

Guys, I need your thoughts on this. I have an 06' IS350 (Navi, 18" OEM Wheels, No ML, etc). Anyway, for a few months now and very intermittently (1 or maybe 2 times a month) I will get a set of warning lights as shown below. This includes Check VSC, ABS, TRAC, and BRAKE (CRUISE was already on in this pic).

Attachment 167106

I have had this happen in all sorts of configurations such as headlights on/off, cruise on/off, stereo on/off, A/C on/off, etc. The only thing common about these occurrences is that it always seems to happen either on the highway or right after getting off the highway. When it happens, I don't notice any degraded engine performance at all.

During the most recent episode, I pulled in to a parking lot to test if indeed I had no ABS or TRAC. I did a quick acceleration followed by a stomp on the brakes. I notice I was able to squeal the tires in the back easily and then during the very hard stop I noticed no ABS feedback whatsoever.

After every instance of this weird problem, everything goes away if I turn the car off and back on again. I am familiar with the gas cap issues (which do give a CEL), but I strongly feel this is something else.

I have no idea how to address this and would really appreciate some thoughts/advice if anyone knows anything at all.

Thanks!
I am having the same problem with my 06 GS430 did anyone ever find a resolution to this issue?????

Same here! I had all those lights up when I made a sudden brake or try to reverse my car against a downhill. Besides this issue, sometimes I have to press the brake hard to have the start button turn green. As I mentioned in the other thread, I totally think this is a sensor issue.

I think Javy answered the question for the OP.
I had the same issue after replacing my rotors. The ABS light is usually a sensor going bad. I had accidentally nudged the front driver speed sensor when i had replaced the rotors. During the course of a week i had the lights come up on the dash for ABS and the other mentioned. I tested the driver and passenger sensors by pressing them in and slightly pulling on them just to see if the light would come on or if the wire had been pulled from the plug. Checked out that the wires to the plug were pulled just enough that the connection was not 100%. i soldered the wire back on to the plug for the meantime and stopped experiencing the lights appearing while i placed the order for the part. Haven't had the issue come back.
Hopefully that helps a little
