I have 2001 Sienna with 153k on it ... My air bag light has been on for months. Per my local mechanic, trouble code 1177 comes up.
How do i find out what this code means? He has already said he has replaced a front sensor (not sure which one) and a relay that is under the hood (not sure which one).
Any suggestions on where to go from here?
I am also having issues with the service engine light as well ... replaced front o2 sensor ... but may not have fixed it ... after driving about 10 miles today ... we cleared trouble code PO420 from computer.

I can't find a listing for 1177. If he was using a scanner, he would have gotten a code starting with a B. For example, there is a B0117, indicating a short in the left hand squib circuit. You need to figure out what code you have before you can do anything, and here's a way for you to do it yourself:
Pop the hood, look for the square diagnostic connector. It's about 1"x3", and has a little flip-open lid. When you open it, there will be a map on the underside of the lid showing you the layout of the terminals. Locate terminals E1 and Tc, get a paper clip or a little piece of wire and jump them. Now, go back in the car and turn the ignition to the 'on' position. You'll get a bunch of flashing lights on the dashboard, but your SRS light should be blinking out a two-code pattern (blink blink <pause> blink blink blink would be code 23, for example). Make a note of this code and report back here, we'll see what you have and get you pointed in the right direction.
I did this on my 97 honda, ie, jumped with a paper clip to get code (read it in my chilton manual) but toyota's didn't sniff at it in manual.
So was very high on honda's easy of getting code.
While we are on subject ... how do i get Service Engine light codes ... easy.
OK ... 1 problem at a time ... what does code 61 point to.
61 is code B0132, indicating a short to ground in the passenger side seatbelt pretensioner. It's a fairly simple circuit if you know where to go, but as a matter of course airbag problems should be solved by professional mechanics, for obvious reasons. Basically, two wires go from the airbag computer to the tensioner, and for whatever reason the computer is reading low resistance to ground. The troubleshooting procedure would be checking those two wires for ground continuity, and if found replace the faulty component. If none is found, the airbag sensor is bad. My experience with these problems usually has the sensor/airbag computer at fault. Wiring faults in toyotas are virtually non-existent, so I would put my money either on the seatbelt assembly (where the pretensioner is) or the airbag sensor.
As far as the MIL, I don't think your car supports this function for engine codes. Toyota started phasing this out in the early 00's. If it does, the same strategy will work for the check engine light, though my support here only lists engine codes by the SAE standard. Most chain parts stores will use a scanner to pull a P code for you though, so it shouldn't be a big deal. Hope this helps.
Getting closer ... I see what you are talking about regarding the Seatbelt Pretensioner ... not sure how all this fits together so going to ask some novice questions.
Wiring is fine ... tested continuity.
Which airbag sensor are you referring to ... i know there are several sensors in front of vehicle ...
Is there a particular sensor that runs ... from computer (main) thru sensor to pretensioner ... or are you talking about the sensor that is in the pretensioner ...
I assume i can get parts from junk yard ... if for example, the vehicle had rear collision ...
I also assume i will need special equipment to clear the codes from SRS System ...
I am having the same problems, checked like you instructed and got
61 and 64. Any suggestions??

Thanks
61 is the code described above, and 64 is an open circuit in that same system. Since you probably don't have a short and an open in the same circuit, I would put my money on the center airbag sensor.
Update ... WOW!! Qslim ... you saved me a whole bunch of $$$$. I found a center airbag sensor at a junk yard for $50 ... and replaced last night. I couldn't have done it without you.
Couple things for rcbrowning ... center airbag sensor is located under airduct in middle console. So have to take bottom part of dash off to get to it. Also, I unhooked the negative ground wire to the battery before i started working on the Van ... and this actually reset my SRS codes ... so i didn't have to take it anywhere to get codes reset (like you have to on the Service Engine Light).
WoW ... what a positive experience! Super glad I found this website and someone to guide me. Thanks again.
Great! I'm glad we solved your problem. And just for reinforcement, don't mess with the airbag system unless you are confident in you're abilities, and always ALWAYS disconnect the battery before you go to work unplugging those airbag system harnesses.. I've seen a couple of people accidentally deploy a bag or two taking shortcuts, and it's not pretty.
