Airbag light panel is ON

[Josepe-sv]

This 2008 model just start the light ON, when the mileage was in 35,000 miles

Is a maintenance issue?
There is no any hit recent.
Can be a sensor?

Can be delete the alert message by reset (like MAINT REQ alert)?

[CTScott]

You can get the SRS ECU to tell you what the code is for the problem by following this procedure:

http://www.yarisworld.com/forums/attachment.php?attachmentid=24313&d=1243385373


1. Turn the ignition off. With a jumper, connect the TC and CG terminals on the OBD port.

2. Turn the ignition on. The SRS (airbag) light will flash in a pattern to indicate the stored DTCs (diagnostic trouble codes). Each code will be short flashes, separated by pauses (for example 32 would be flash, flash, flash, pause, flash, flash). Each 2 digit code will be separated by a longer pause, and then the codes will repeat until you turn off the ignition.



To clear the stored codes and reset the light do the following:

1. Turn the ignition off. With a jumper, connect the TC and CG terminals on the OBD port.

2. Turn the ignition on. When the SRS light starts flashing the codes, within 3 to 10 seconds remove the jumper frm TC. After 3 seconds the SRS light will come on solid.

3. Within 2 to 4 seconds after the SRS lights, reconnect the jumper to TC.

4. Within 2 to 4 seconds the SRS light will go off. Once it does, within 2 to 4 seconds disconnect TC.

5. Within 2 to 4 seconds the SRS light will come one solid again. Within 2 to 4 seconds after the SRS lights, reconnect the jumper to TC.

6. Within 2 to 4 seconds the SRS light will go off. One second later, if all DTCs are cleared the SRS light will flash steadily on and off. If codes are still registered it will flash in the pattern to indicate the stored codes.

wow, thats a fair bit of instructions just to clear DTC's, is it just a jumper wire, straight short? or should you use a resistor?

Actually it's a nice thing that you can clear them at all without needing a TechStream tool.

Literally just a jumper wire is all that is required (i.e. you are shorting the two pins together).

[bert66]

G'day CT. Went through the process several times. Problem still not solved. The light would not go out at step 4. Do you have an idea of what that would indicate. Regards Bert

I have just done the diagnostic and the airbag light keep on flashing steadily. I'm not sure what is the codes as it wont pause in between, when i disconnect the pin, the airbag light solid. What could be the possible problem?

Thanks

That procedure is only for 06+ Yaris.

[nseries]

Thanks for the reply. I'm planning to send to service center if there is no other manual ways to get the codes and reset.

[nseries]

I managed to get to scan the codes from my friend. However,I just contacted the authorized service center and i made an appointment for next week diagnostic.

As using my friend diagnostic tools, i got an error code of U2100 DTC. I've scanned through at internet and it reported CAN communication off or dysfunction. Can someone elaborate more on this? I'm just curios as the CAN bus off will light up the airbag symbol in my car dash.

Thanks all...:)

That CAN bus error is a generic one, which probably indicates that the scan tool does not support the protocol for talking to your car's SRS ECU.

[nseries]

Hi CTScott,

Thanks for your prompt reply. I was worried and look around at the web regarding this error code U2100. It seems so serious if that is really the problem of CAN BUS dysfunction. I shall be able to get back to here whats the possible cause after i send my car to service center next week.

I hope nothing serious will happen to my SRS airbag system or the computer inside the vehicle.

Thanks so much,
Cheers,

From all the way Malaysia! =)

One of the air bags losing its activation pressure could make the light stay on. I'll guess that they have low air pressure sensors similar to the valve stems on the wheels.

I don't know if you intended this as a bit of humor, but this could not be more incorrect as to how air bags function.

[tooter]

I'm glad to amuse you CT... but even more humorous, I was serious. :laugh:

Air+ bag = a bag full of air.

What activates airbags?

[CTScott]

What activates airbags?

They are basically little bombs. There is an explosive charge in the squib that is electrically detonated to rapidly fill the bag (with hot, stinky gas, as opposed to air). The SRS system makes sure that they are ready to fire at all times, by running a low voltage through the squib and looking for the voltage drop across it. That allows the system to detect that the squib circuit is open (broken wire) or shorted.

[tooter]

Wow... stinkbombs. Thanks so much for the information CT, I understand now. I had just guessed that they were powered by little CO2 cartridges.

[nseries]

Its just too complicated for me. :( I just hope the SRS airbag wont deploy out of sudden. I need to drive to work everyday until next week for service appointment.

[cybrjoe]

My srs light is on after a big rain. I checked the code and it's " 14 ". What can i do to resolve this problem. Thanks

That's a new one - "Front Airbag Sensor LH"

That would be the sensor mounted to the left side of the radiator frame that detects the impact. You will have to pull the front bumper to get at it. It has a connector that plugs into it, so the first thing I would check is if moisture got into the connector.

[cybrjoe]

to unplug the connector on the senso i will have to pull the front bumper ????? It is a big job??? And how can i do that. They dont have an other option to unplug it from the top. I know where is the sensor, i see it from the top but i cant see the connector.

You don't have to completely remove the bumper, but you have to pop the top of the bumper to get to them. That just means releasing the 5 clips along the hood edge and two in the front edge of the wheel wells (which you do by pressing in the center and then pulling the whole plastic clip out) and releasing the bumper clip, where the bumper meets the fender.

This is what the sensor looks like. You will have to remove the two bolts and pull it out of its channel to unplug the connector.'

thank you, your the king. I will check the connector and i will come back after.

i try to reset the srs ecu but i cant. That's, what i did: short the 2 pins, srs light began give me code, open the short 3 sec, short 3 sec, open 3 sec, short 3 sec, open 3 sec and short. After that, the light gave me again the code 14. Why ?????. Is that a good procedure for yaris 2007??

The procedure is good, so if it won't reset, chances are that the sensor is bad. To verify, you can swap the right and left (as they are identical parts) and the code should change.

[cybrjoe]

Is it dangerous to change sensor. I dont want the airbag blow out.

[CTScott]

Just disconnect the battery before doing so. Other than that there are no issues with swapping them.

[cybrjoe]

i switch the 2 sensors and the problem now is in the right side, so it's the sensor the problem. So now, where i can buy the sensor on internet.

They run about $70 plus shipping from the online parts places. I have a spare that I picked up a while ago that I could do for $40 shipped.

[cybrjoe]

it is a new one or a used??? And you are shure that it work. And can can i pay you. Come online to chat with you.

[CTScott]

It's a new one that I picked up because I thought I would need to replace the one that I posted the picture of above. It actually turned out to be fine, even though I had to bend the radiator frame away from it to get it off of the damaged frame.

I can take paypal for payment. I'll PM you.

[frambach]

Well, I've been jammed up on the DS Airbag light too. Mine is a 2008 Liftback with just a shade over 90k miles.

I'll try reading the codes but can just about assure you its the clock spring/spiral cable as it only comes on intermittently and usually when going around a turn.

Has anyone found a cheap OEM one anywhere? Seems like as much trouble as everyone's having maybe a new OEM has been revised to last longer.

[frambach]

Just checked the two closest 'yards' for Yaris bones and neither have one.

BTW, CTScott, you are very knowledgable and a great help. I don't post here much but that doesn't mean I don't lurk here quite a bit and glean out information for my car maintenance. Thumbs up to you.

[CTScott]

It doesn't have to be a Yaris one.

2007-2009 Highlander and 2006-2008 RAV4 used the same one. (Part number: 84306-22010)

[cybrjoe]

Thank you CTScott, i installed your sensor and it work perfectly. Thanks again !!!!!!

[jobob]

I am nervous about trying this. Is there a chance to short the wrong terminals and set off the air bag ? Do I have to connect the airbags before resetting this module using this procedure ?

[CTScott]

You can't set off the airbags using this procedure. The worst that you could do by connecting the wrong pins is to pop the ODB fuse, which only provides power to the OBD II connector.

You do want to have everything hooked up before doing the procedure, otherwise anything that is not connected will cause an error to be reported, and you will not be able to clear all of the errors (and turn off the light).

[jobob]

Ok, I reset the module and got the steady blinking. But it didn't reset. Found that the driver belt had fired in the normal position (Must not have been worn when crashed). Bought used (Undeployed) belts off ebay. Just got them but they are stuck in a retracted position and won't pull out. I am afraid they are deployed and the seller just thought they were ok. Do you have to apply power/plug the belts in to allow them to release or are the deployed if they won't pull out when the belts aren't installed ?

thanks

If the car was in a crash you can't completely reset the SRS without either replacing the SRS ECU or clearing the "black box" info, which is stored in a EEPROM on within the SRS ECU. I have successfully reverse engineered the SRS ECU reset process and can do the clearing process.

As for the seat belts, try holding them in the orientation that they would be mounted in. There is a little metal ball that locks the seatbelt when the car is in a position other than full upright (this is separate of the pull it fast locking mechanism and the explosive pretensioner). This is the correct position:

[jobob]

Ok, that did it for one and the other I am sure is fine too..

so using the procedure above, I can't reset the module ? I got it to the point the airbag light flashed consistantly but then it gave me an error which pointed to the seatbelt. I figgured I could put the new belt in and reset the module again using the above technique ?

thanks for all you help

You can try the procedure and once the bad seatbelt(s) are replaced, you will no longer get the code(s), but if the SRS light remains on after that, then a reset or replace of the SRS module will be required.

I have a couple of different part number ones on my test bench (there are 4 or so different ones, relative to the year of the car, how many airbags, etc.) If you want to PM me your VIN I can verify which part number yours has, and if it matches one of the ones I have I can ship a clear one to you and have you ship yours back to me. The online places that offer the service charge $50 to do so. I would be willing to do it for $30.

:cry::cry::cry:Hello.

Some time ago I had problems with the code 14 in the end the problem was the wiring.

A couple of weeks ago, the srs light was returning to be turned on, but only when he turned the wheel, was paid in the next engine start.

Yesterday, I remain fixed, I thought it was past connections, so I went back to splice the wires.

Now I have the code 14 and 51, my question is, if I change the front sensor wires with the battery connected, the code 14 again, or should automatically eliminate, or scanner is required to remove it.

The 51 is the spiral cable, even should I check.

I appreciate your valuable help, I'm desperate for that light.

The 14 and 51 codes are both ones which will not clear on their own or by disconnecting the battery. Look at the first page of this thread for instructions on how to clear the codes, using the same jumper that you used to read them.

[edelgados27]

Thanks for the reply.

Again turn off the light, but determined that only turns on when I move the steering wheel fully to the left, for example in reverse.

As one of the codes is 51, is likely to be the coiled cable, for the symptoms.

With the lights out, if I use the cable actually tells me that the error codes are 14 and 51, the 14 and this resulted for months but 51 is new.

It's interesting, because when I turn on the light, to turn off and on the engine shuts down, the initial check.

Yes - 51 is the spiral cable. With it coming back when you turn the wheel fully to one side the ribbon cable inside of it has a damaged spot.

Son of a gun. I forgot that the recall does not apply to "all" yet. I would call Toyota corporate to complain, and hopefully get them to expand the limits of the recall.

They said my model only have 2 recalls.

But doesn't have the Bad clock spring recall.
Can I fix it by myself first, then apply an imbursement when my model have recall?

You replace it yourself, but I don't believe you will ever get reimbursed. You can pickup an aftermarket one off ebay for $35. Swapping it out is not all that bad. Here's a video of what is involved:

So my airbag light is on in the instrument panel, this is most likely to be a code 51 and this is what the spiral cable recall was talking about?

I already received the interim recall letter, but I haven't received the remedy letter, anyone know when it will arrive?

You can read the code using the procedure to verify, but if it is the spiral cable, (and you have the recall notice) I would get it replaced ASAP. I have not seen anything regarding how quickly the new ones will be out, but they will install a replacement of the current type for now (and that will likely be fine for a few years).

[jra]

Wonder how many people have been injured or killed by air bags and air bags that failed to deploy verses the number of people saved by them?

[GeoffreyVB]

Was able to reset the codes and now I'm only getting code 32... sounds like this may be the passenger seat sensor needing to be zeroed or replaced. Unfortunately I don't have a way to zero it...

Super appreciate Scott and his seemingly endless knowledge on this stuff though. Could not have gotten this far without clearing the other two codes.
