Car won't start please help - No READY light.

Yes when the airbags deploy the System Main Bus is disconnected. The dealer should know that! You took it to a Toyota dealer and they replaced airbags keys immobilizer, key fob and did not activate the System Main Bus? Sounds like something rotten in Denmark. Anyone care to comment?

 

i would strongly advise against replacing your own airbags.

even mechanics are leery about replacing airbags, much less having someone do the job who's never done it before. if you don't know why your car isn't starting i'm leaning toward you being "someone who's never done it before."

the situational difference is, if you get hurt while doing this you're on your own. your mechanic gets hurt, his medical bills are paid for as a work-related injury and you still only pay the going labor and parts rate regardless.

i know it's expensive but i wouldn't take the risk of doing it myself if i were you.

 

ok. lemme see what i can find out.

you can never assume people on an internet board know what they're up to- i hope i didn't come off as too offensive then. always best to err on the side of caution and not send someone in to bite off more than they can chew.

 

dugi:

I'm reasonably certain there were major changes made in the Prius between 2003 and 2004. For your safety, check out the procedures for installing the air bags on the 2003. They may well differ from those of the 2002.

Galaxee will be a good source of info for you. Wait for her advice.

cheers,

This makes no sense. The INFO/lights diags screen trick doesn't
reset "the computer", it can clear a couple of codes related to
the stereo and nav but that's completely unrelated to the hybrid
system. And CAN is a data bus, not something you reset. If you
were still getting no-start condition I was going to ask, do you
get *anything*, i.e. does it at least power up to ACC mode? What
you probably saw was the effect of the fourth startup you tried,
which is when most error conditions self-clear if the cause has
been removed in the meantime.

Well I am not sure about 03 but you can down load all or part of the service manual here; http://techinfo.toyota.com/. I got some of the 04 information there but I was not paying any attention to other years and did want to pay up to check but you can sign up by the day find the info and download it.

 

edit:

the HV battery relays are open, so that's why you're not getting any current. he's done some digging and hasn't seen anything in the repair manual about resetting it. they've actually never had to do that at his shop, their body shop does all the body and airbag work, and they fix anything mechanical that's messed up.

still digging... :mellow:

 

have you checked the 15a AM2 (located in the engine room junction block) 10a SRS ACC and 10a ACC fuses (both in instrument panel j/b)?

any DTCs?

DTC 3125 converter and inverter assy malfunction- info code 308: the inverter will recognize the signal from the srs sensor and shut itself down- there's no inspection procedure listed in the repair manual or steps to take written down there.

could you tow it home, replace the airbags and all those sensors and then try to start it back up? if the above DTC is causing the problem, restoring the system should set things back to normal. after searching over 2000 pages of repair manual and EWD... sounds like replacing the airbags and sensors and etc is what it will take to start your baby back up. (yes, he even went over the options tree for the scantool and saw nothing about a main relay reset or anything accident-related)

Congrats on getting your car going. Very industrious of you.

I will admit that I haven't followed this thread that closely, however if there is anything I completely and fully understand about the car business now, its that dealerships are always looking to cover their behind, and if our society weren't so litigious, they probably wouldn't be compelled to do that so much. But instead of leveling with their customers when they are covering themselves from potential legal repercussions, they feed you a lie and don’t complete the work.

It would have been smarter for the dealer to activate your immobilizer and then have you sign a waver or release form for taking away a vehicle that didn't have full safety equipment. I don't believe that a dealership or body shop can legally send away a vehicle in which its factory included safety equipment is known to be non-functional. If a body shop or dealer has been given a car to put back on the road, it has to have its safety stuff repaired and operating.

That is what the dealer should have told you, instead of the other line they gave you.

 

well done dugi!

apparently the inverter doesn't require the airbags to be replaced as long as the car has been restarted to assure it there is no danger of electrocuting emergency response peronnel or passengers or anything.

initially we figured it should be able to run, but after searching the repair manuals and not seeing ANYTHING we started to wonder if the shop was indeed right. we couldn't find anything to prove one way or the other.

we should have moved on to the immobilizer and key, to see if that was done correctly.

glad to hear everything turned out okay and you didn't have to get screwed by the dealer. yes it's a shame that stuff happens, and that's why we try to offer what we can. and thanks for sharing some valuable information with us.

 

Not sure what the liability or safety issue is with not having the airbags work, I would think more than 50% of the cars on the road don't have airbags to start with. It was not that many years ago that only high end cars had them as an option, let alone standard equipment. Sure it is safer to have them, but it is not like driving around with bald tires a bad steering gear.
