When this same problem occurred for me, I cleaned and tightened the gas cap, then disconnected the battery cables for about 15 minutes, and then presto, no more idiot lights. I assume that by resetting the computer by disconnecting the battery cables, if something was wrong, after reconnecting the cables the idiot lights would come back on, right?

 

cleaning the gas cap...what have ECUS come too?

 

The "trac off" and "vsc" lights (and obviously the airbag) both came on when i changed steering wheels also. Im going to take to the dealer sometime soon hopefully it can be taken care of. Will these lights being on hurt performance in any way?? A reply here said the gas mileage would suffer. Does anyone know any FACTS?

 

Jones, just try disconnecting the battery for a few minutes, then connecting it again.

 

Tried that man, didnt work, thanx though

 

damn... this many people with the lights on. well, mine is also on and it idles like crap and once reached 3000 rpm, it boggs.

did anyone experience this? I took my batt terminal off to clean the corrosion and after I was done, termonal cables back on and this all started to happen. The car will run, I had to drive it to work and back today but I like said, it bogs after 3000 rpm.

 

My car ran great... just had the lights on.

any words? :-/

 

My car rand good with the lights on, only a little slower off the line. Turns out my timing chain was off 4 teeth.

 

MEE TOO!!!
I was told it's just the sensor and they are replacing it, I hope it isn't anything more!

I hate those lights! They've reset the sensor several times,,,
Check Engine, VSC, Trac Off GO AWAY!

 

You know, my problem was the MAF sensor. I bought one off ebay for like 46 bucks shipped, slapped it in and all problems solved. how is your car running?

what did you do that caused the lights to appear?

 

My car needed a new cam shaft?...
They replaced it and the lights haven't come back on. Yippy!!!
It's weird that o many people have had that exact same problem. All around the same mileage too! Well, the dealership told me that all of the lights come on whenever anything is wrong so we could all have a different problem. I'm not sure what caused it but I'm very happy those pesky lgihts are no longer lit!

 

 

i would like to know where the EFI fuse is located on the xb

 

So do we have a definitive answer as to what these warning lights mean? My '05 with just under 72K lit up tonight with the VSC/TRAC OFF/CHECK ENGINE light combo. Seems to be driving okay, I can't tell a difference in anything. I've been using a shop for service that's not my original dealer... do I have to go to the dealer for a warranty thing like this might be?

 

Update from my post last night... I filled up this morning, and the lights went off! They had come on when the gas gauge was between halfway and a quarter tank left. Very strange, I guess I'll need to keep my eye on it.

 

My '06 xB had this same group of lights come on. Once in awhile they are not on, but are mostly all the time. My dealer said it was the cam timing gear, and that he has seen it on a couple other xB's. They are replacing it under warranty (my lights came on around 25,000 miles, and I now have close to 29,000 in my first year. I'll update to let you know if it worked.

UPDATE: I got it fixed under warranty last week, the tsc works again, and the lights are now off. They said they replaced the cam timing gear.

 

Last night @ 38,??? miles the VSC, TRAC OFF, and CEL all came on but the car ran normal and didnt notice anything out of the ordinary...I have had my intake on for about a year with no problems...The lights stayed on for about 35 miles, then I shut the car off and let it sit for a few minutes...Started it back up and the lights were now off...Drove it home another 35 miles and the lights did not come back on...Not sure what the problem was...I did nothing to reset the lights, they just went off on there own...

 

Well, my RS2 with 54k miles on it has the issue now.

I was driving back to the office from lunch and the CEL/VSC/TRAC OFF lights all came on. I stopped by my dealer (it was on the way), and they said they were swamped and for me not to worry and bring it back in the morning...so....

(and yes, it has the yellow powdercoated Scion/AEM CAI)
