B1811: Clockspring was the culprit. Replaced it with a new one.

1. I've noted that Amazon has several listings for these clocksprings for under $20 now but with no reviews. Can you give us more details on where you got your replacement clockspring and any information (brand or model name / number) that might make it easy for others to find if they wish to try a similar one? (They probably are all coming from the same factory in China anyway?)

2. Also, did you have to use a steering wheel puller to remove the wheel or were you able to get it to lift off after loosening the center 19mm nut ?

3. Was your horn and cruise control still working normal after you got the B1811 code showing for the clockspring ? Some have mentioned that there are a number of wires in the clockspring "wire tape", some which may also powers the horn or cruise.

Thanks for updating this thread with your findings.

1. I got a cheap one off eBay. Not sure if I can post links here, but this is the one. Clock Spring For Toyota Corolla Matrix 8430602110 New Spiral Cable Clock Spring | eBay

2. I didn´t need to use a wheel puller. I loosened it and hit it side to side until it knocked off. A lot of force was needed though, so if you have access to a puller, just use it. Don´t remove the nut all the way or you may Jackie Chan yourself in the face.

3. Yes, my horn and cruise control were both working fine when the B1811 code showed. So probably only one of the cables inside were broken. After installing this cheap clockspring, the code went away, and the horn and cruise control still work, so it has all the necessary connections.

Update: Problem solved!
A mechanic checked out the problem and found that the passenger seat belt retractor was causing the short (code B1905). What else he did to solve it, I don't know. I'm glad I didn't need to order a costly new replacement part.
I now have all 6 airbags ready and loaded, hopefully they will never have to be used.

So for future references, here's a quick reference:

B1811: Clockspring was the culprit. Replaced it with a new one.
B1905: Passenger seat belt retractor (pretensioner) was giving this short code. I'm not sure what was done with it, but it wasn't replaced. At least this is a reference point.

Reviving this thread. I'm still fighting with the B1905 code. Can't get in contact with the Diag Guy that was helping me out.
I tried testing the resistance of the old and new buckle, also the drivers one. I can't get a reading from any of them. Anyone have an idea what I could be doing wrong? I did verify continuity on the old one, didn't test it on the 2 installed ones, didn't wanna mess anything up.

 

[Roscoe Thiessen]

OK I'll have to get some help with that, I'll try it some day when I have more time.
I got it from toyotapartsdeal.com, it came in an OEM toyota plastic bag.

 

[Roscoe Thiessen]

Not at home, but I can get one.

 

[Roscoe Thiessen]

So the buckle arrived today, installed it, erased the codes and the B1905 is still there . Ideas?

 

[Roscoe Thiessen]

Yes it´s cheap, but taking the OEM one apart, I don´t see the reason that they should cost +$200. Its just plastic with a ribbon cable and some connectors, from what I can see. Should one try to solder the original cables bridges for when the cheap one breaks?

Wow, so that´s not just over here then. They once started doing smog tests and all that here, but leaving $10 on the seat helped every car pass inspections lol. They eventually stopped the tests. Some vehicles look like they calculate their mileage based on km/L of oil.

Yup. Many of the larger Honda´s sold at the dealership here are imported new from the US. Not sure about other brands. Toyotas come from Argentina and Thailand, I think. This 14 year old Corolla is considered pretty well equipped here, since cars made for the market barely need to have wheels and a steering wheel, lol. Only about a year ago I started seeing new sedans having ISOFIX here, for example. Drivers and passengers airbags have only been standard for a couple of years. You could only get Cruise Control on the high end vehicles like SUV´s and trucks (only the most equipped versions).
Then you see a 14 year old Corolla having all that, and more, and you kind of forget it was crashed.

This probably all doesn´t belong here anymore, I just find it interesting how different the markets are. I´ll update in a few weeks on the buckle.

Update

After 4 long weeks of waiting, my $8.49 clockspring arrived. Installed it yesterday night, and the B1811 is now gone.
Now that 1 out of 2 problems are fixed, it's time to order the buckle and that should fix everything.

@TheDiagGuy A guy in New Mexico, in 2010, crashed this Corolla (from damage reports, he must have hit someone with the front left bumper, skid out of control and rolled over). It was declared salvage and shipped to Paraguay. Most of the American Corolla here are wrecked, flooded, or otherwise damaged.
When fixing the car here, they just taped over the bulb to hide it. Sells better without an airbag bulb on. They must have thought it was from the crash, but these codes most likely aren't from the crash, just normal wear and tear.

 

[Roscoe Thiessen]

So not really an update, as the parts haven't arrived yet, but I found out why the airbag bulb wouldn't turn on. The picture says it all ?

I continued a conversation with TheDiagGuy so that the forum wouldn´t constantly get bumped because of small questions. So that the information is available for everyone that has a similar problem in the future, here´s the conversation (with his permission).

Me: Hello. Can you confirm this being the right part?
73230-0W051-B1 - Toyota Parts Deal
:,
Him: It looks right to me.
Me: OK. Is clearing the codes with an obd2 scanner the same as resetting the SRS light?
Him: The scanner that you sent the screenshot of your codes with should be able to clear the codes which will in turn - turn off the SRS light if the repairs were successful.
Me: Ok, I was able to remove the open code, so that works.
Another question that came to mind: if it´s the buckle switch that´s broken, then why does the computer still recognize if the male part is inserted or not? Are those not linked together?
Him: Because the resistor in the female section is shorted, hence why it throws a "squib shorted" code.
[...] You were lucky it threw the open code when you disconnected the receiver, because if it hadn't done that, I would not have been able to help you much more unless you had a DVOM and were willing to tear into your car a bit.

 

[Roscoe Thiessen]

Considering it's a low fail item (I think) , I'll take my chances with a used one at first.

 

[Roscoe Thiessen]

Okay I understand. Would an aftermarket Chinese one work? Shipping to Paraguay is very expensive, so aftermarket is always a good option for me. I found this on ebay : https://www.ebay.com/p/1pcs-Auto-Ca...et-Plug-Connector-With-Warning-Cable/5031115433?iid=312293728736&rt=nc&thm=1000.

Or should I buy a used one from a crashed Corolla? Probably a better buy than a new Chinese right?
Thanks for the explanation, also.

Thanks a lot for all the information. It will probably take a few weeks for everything to arrive and install, so I'll update if these fixes work or not.

 

[Roscoe Thiessen]

Yes, that is the open code for the "squib". Replace your seat belt receiver on the passenger side seat.

OK. Is the receiver the buckle assembly? So that I know which part to order.
What does squib mean? Not even Google knows

 

[Roscoe Thiessen]

What is your specific year, model, and trim level? I have access to a lot of different information systems.

Edit: Nevermind I found it on another one of your posts.. Stand by.

B1811 is gonna be the clockspring/spiral cable - whatever you want to call it.
B1905 as you said is a rarer code, the code is essentially saying that the squib (Which is a word that I refuse to define) for the front passenger seat belt receiver is shorted. So what I have done when I get this code is unplug the receiver and see if I can get the module to set an "open" code. If the open code sets, then your issue is the seat belt receiver. If it still sets a short code, then your issue is either in the wiring or the module. Try this and get back to us.

After running BlueDriver with the yellow connector under the passenger seat disconnected, I got a new code: B1826. Is that good?

 

[Roscoe Thiessen]

I'm outside the USA, so I'm basically on my own. But the clock spring isn't under recall anyways, as far as I know.
