I bought an OBD2 scanner and it told me nothing. No codes present. I then read somewhere about a reset procedure. I figured if the problem is real the light will reappear. Thus I reset the warning light and it has been a week with no reoccurance. With all the electronics in these vehicles these days there are bound to be small glitches and the computers will always latch on and hold them even though they are not problems with the vehicle.
 
Just saved myself $100+ and who knows how much more potentially and most of all, all the hassle and aggravation to/from and at the dealer.

Good for you. The scanner already paid for itself.

Robs sienna, would you tell me which OBD2 scanner you bought? Thanks.
 
I have the similarly problem. After I reset the tire pressure light, the SRS warning went on, intermittently. Too bad, my warranty expired last month.
 
Based on manual, it is the problem of side/curtain airbag. But I really feel it is a computer glitch. I am thinking of reset the light and go to the dealer if the SRS warning comes back.

I got thesame problem as yours my friend. Engine light / VSC / Trac off lights suddenly came on on my toyota sienna 07 LE. So if your dealership figure out whats wrong, Can you email it to me so i can do the fixing myself. cause I think my dealership don't have any idea whats wrong with the van, i might as well follow your lead.

What did you end up doing with the SRS warning light? Mine flashes as well and I am just not convinced that their is an issue. I am out of warranty due to mileage, but I take great care of the car and I find it hard to beleive that the airbag would malfunction after only three years (no accidents and no use). Any suggestions on this would be greatly appreciated.

This reply is a little late, but my 2004 has the same problem-no speedo ,no odo, and check engne lite-they say it's the abs actuator assembly-something like 2 thousand ++ for the part. My sienna only has 26,000 miles. Needless to say, I'm pretty disappointed and will write a letter to Toyota. Maybe it's not such a rare problem?

I just got a 09 sienna LE. Within 800 miles the 3 lights turned on. They said it was the oxegyn sensor. 2500 miles later same thing happened again. This time they say its the other oxegyn sensor. Has anyone had these types of problems on a brand new Seinna?

Yes, but it turned out to be some rodents that had chewed up my wiring harness!
 
I hope you don't have the same problem.
 
Come to think of it, my problem was with a knock sensors, but that was just a strange symptom, the actual problem was a chip munk.

Blinking red light with key? by ateixeira

Anyone know what that warning light is for?
 
My van is working fine, but when I lock my doors I get an occasional blink from that red light in the dash (shaped like the van, but with a key in the middle of it).
 
Any clue what that is? Has it always been there, only I never noticed it until now?
 
This is a 2007 LE with package 3. I made sure all doors were closed properly. Reinserting the key made no change.

Hi been following this discussion closely. Our Sienna has just started having these three light solidly on all the time. Check engine, VSC, Trac off as wellI it has 39k on it for mileage. All fluid levels are fine, must be a gas cap or similar sensor reading gone whacky. So what is the brand of scanners people have purchased to do the ox sensor reset. Little freaked out at the suggestions of the 3000. bills to repair/replace items that are really a false code. What do you all suggest as the starting point.
