Hi.
Try this.
Please report.
Pass PM.

Unfortunately both of them don't work.

I have trouble code B1801.

Any ideas?

[rrador]

B1801 - open in driver's side squib circuit

problem is with your driver airbag, dumps are good if this is the only code you are getting.
Check connectors for the airbag....on most toyotas i need to replace those connectors.

[meteor80]

But when i disconnect driver's airbag (in steering wheel) I have another one code.
But now I don't remember the number.

[rrador]

what are you suing to read the code? does it give you a sub code?

[rrador]

That airbag has 2 steb squib circui and it has to connectors.

So the second code is probably B1811 - open in driver side squib 2nd step circuit ?

Check and let me know.

If thats the case you just need to replace one connector, i can***8217;t remember which one is which now but unplug one by one and check codes to see which one you need to replace

[meteor80]

To read codes I have maxidiag JP701.

Autel (http://www.auteltech.com/jp701.htm)

It works preety good and codes was always correct- i was checked that with VCDS or LEXIA.

About airbag.
Old and new airbag has only one connector.

[rrador]

ok my bad then, what year is the yaris?

can you check what code you get when you unplug airbag.

[meteor80]

Year 2008.
Tommorow morning i will read codes.

[meteor80]

When I unplug airbag in steering wheel i have two codes:
B1801 and B1802.

[AMLGAR]

u have a problem with one squid (a plug)in the clock spring,:bebored:or is not plugged ok, to open the pins in the bag, but read this toyota always reads and clear DTC codes even if the crash code is there, if u light stay on, with no codes the crash still there.

[meteor80]

I have only one squib in drivers airbag. It's the same code when I connect resistor in place of airbag.
When i disconnect clock spring under wheel i have two codes like I said before.
When I connect resistor in place of clock spring i have code B1801, so I think that problem is in the dump.

[weltune]

try this n post result

[meteor80]

I will try in the evening and post results.

[meteor80]

Hello again.
Today I haven't got time to check last dump. I will try tomorrow morning and post result, but I have an idea.
That Yaris was weird since start. There was activated onnly driver airbag - without passenger airbag and belt tensioners.
Passenger airbag wasn't disabled. I have never met Yaris with an one activated arbag. Maybe problem is in airbag module?
If i would like to buy other (used) module, do that mast have the same numbers? or only quantity of airbags must be the same.
I'm asking before i don't have tool to code a new module.

[meteor80]

Hello

Unless "weltune" it doesn't work.
I thin that I will try with other module.
In my opinion that one is broken.

I will post results when I change module.

[raddi]

Module number has to be the same..

[meteor80]

Hello.
Today i received other module and everything works ok.
But when I program old module using dump from new one still B1801.
So i think that old module is broken.
Here is dump from new module.
