Two days ago, I was out running some errands after work, and after one stop, I started up my 04 xB, and the Trac Off, VSC, ABS and Brake lights are on. They certainly were not before that stop.

Now, I have a Rostra cruise control that I installed this past May, and no LED brake lights. My brake lights and cruise control work, and the car drives normally (no loss of power or anything). However, the idle is a little bit rough. I am not exaggerating when I said that the car was ok when I turned it off, and throwing these lights when I turned it back on 45 minutes later.

I searched several times, and I couldn't find the exact set of circumstances that I am in (several folks have had things like accident damage and shoddy LED brake lights cause weird things, for example).

Any insights? I am going to run down to Autozone at some point today to see if I'm throwing any codes, but I don't have a CEL, so I'm not sure if that will tell me anything. Naturally, I'll update once I have that done.

Thanks!

 

Ok, so Autozone's scanner got an error, and confirmed that it's just my car (the scanner didn't want to work for me and me alone). wtf.

 

buy a scan gauge II... that way you get see what kind of error you have when it happens...

 

I had that happen to me in my 04 xB as well. Out of nowhere, all three of those lights came on. Lucky for me I was near a fairly new Scion dealership. They were able to take a look at it and noticed my catalytic converter went and the dealer replaced it free of charge. :D

 

check your vac lines

 

Im fairly certain something related to your Brake/Suspension is at fault. I haven't had anything like that happen to me, so I am at a loss of suggestions other than have the code read through a dealership or a reputable repair shop. Once you find out that code (if any) report back here and I'll try my best to help you find it. Keep us posted.

 

sounds like maybe one of the ABS sensor plugs has come loose or lost connection at one of the wheel hubs. Might wanna check that first.

 

bump this UP!!!!!!!!!
so did you find any info???? have you fix it yet???

i just had the very same 4 warning lights come off since yesterday. but it happen after i took off the battery ground(-) wire. after 4 hours, i hook back the ground cable to the bat, start the car, and all 4 warning indicator lights up and stayed.
