Hello all,

Me again,
One of my last things to sort before a mot is getting the airbag light to go off.

I am getting 2 codes, B0021-1B and B0029-1B left and right curtain deployment control 1.

When I look at live data, these two airbags are showing 10 ohms resistance which is too high.

Anybody know where to start looking at fault finding this please?

Many thanks

RCM faults can be difficult to trace, what the fault reads is not always the fault present.
You could try disconnecting the airbags, ignition off, and replacing with a 2 Ohm resistor, then repeating your test.
If the same fault remains and least you then know the airbag itself is ok.
