Hey guys,

long story short, I was off roading in my 2011 CM Tundra, went through a steep dune side ways and BAM, all curtain airbags came out. :eek:

I know I forgot to disable them :(

Anyways, the stealership wants almost 8K$ :laugh::laugh: and the bad news there's only one toyota stealership in my country, besides that airbags can't be shipped.

Right now i'm looking for used airbags but my concern is the trigger.
Should I replace the computer or it can be reprogrammed? TBH i'm not sure how it works and i'd like to here your advice.

Thanks :D

I think that's not possible with this stealership.

Where is this ecu located? I look for new or used one.

Thx

I'm pretty sure the dealership is going to require you to go new. I thought you were doing the work yourself.

The air bag ECU is located under the middle of the dash. Its bolted to the transmission hump on the floor. It is hard to get to. I hope you have small hands.
well the dealership doesn't sell tundras in the first place but they do sell the sequoia. I'm sure they'll say it's not compatible with the tundra. I'll see if I can reprogram it first or i'll get a new one from abroad.

Thanks for the help guys.

I am not sure about the way things are now. I work for Toyota till 2007. When I worked for Toyota all sensors were a one time use. If the air bags were deployed the sensors had to be replaces as well as the squib cable/clock spring. I was under the impression these were a g force sensor and could not be repaired or reset. There were many set ups, but the typical set up was two front sensors by the head lights, one below the center console, called the main air bag sensor. This would be for a frontal collision.

If the car had side curtain there would be one or two sensors per side at the A,B,C pillars. Another thing to look at is your seat belts. Make sure they pull out and go back all the way. There is an explosive charge at the base of the seat belts to pull them tight against the body, to prevent someone from hitting the wheel or sliding under the belt if the belt is loose or the person is wearing a bulky jacket.

It may have change to air bag ECUs and are able to be reprogrammed but this I am not sure. If they are able to be reprogrammed and calibrated ok. If not, I am not sure I would have someone tell me it can be done other than a very very reputable body shop, the dealership or Toyota saying it is ok to do. You are having SOMEONE ELSE PACK YOUR PARACHUTE!!! Or your wife and kids!! Make sure they are correct.

Thanks for the info. The seat belt is stuck and cannot be pulled now. It wasn't on me during offroading but I'll see tomorrow what can be done.

All good points.


The SRS is not that complicated. It needs to do a continuity check every time you start the truck. After that, the only thing that tells the bags to go off is the ECU after it receives data from the sensors. If a sensor is bad, you will have an air bag light on.

The SRS system is built to be simple and reliable. The ECU has the hard job in telling what bag(s) to blow.
So if I replaced the ECU and the airbag lights is gone, i'd assume that the system is working again?

regarding the seat belts, is there anything I should also replace?

Thanks

If your seat belt is stuck, then the retractor needs rebuilt. The only way to make them work again properly is to remove them and send them to the same place that I listed above.

As Shasta Said. It sounds like you have a reasonable reason to have the insurance fix your truck.
That's not an option because I have partial insurance. anyways, this thing looks like it would be a pain to fix. I'll take it to a garage tomorrow and we'll dismantle the whole roof and we'll see what can we do.

Thanks all for the feedback
