Who can identify the Thermal Fuel in the Air Bag Blue Box

& how can you test it when the module is out of the car

The thermal fuse is in the narrow white bit, along with a resistor. As for testing, like you would any other fuse.
I have a write up on it
I got some from EBay, keep meaning to get round to changing mine, but keep forgetting.
I will have to look for the ones I got!

I gave Simon my spare ‘Air Bag Blue box’, today
To try in his car.
The lamp on the dashboard, was flashing code 53
But if you could prove the Thermal fuse out of the car.
It would save a lot of messing around.

The problem with code 53, is that it generalised the fault at the SRS module, which doesn’t help much!

All this is above my pay grade . So what you are saying is change the blue box ?

If you have a known good one, then yes.

But any that get repaired need to be tested somehow

I’ll find a man (or woman) who can do it… my soldering skills aren’t up to that delicate work

I’ll bring a Blue Box & tester with me on Sunday
& May be, do a practical demonstration of testing the Thermal fuel

I will see if I can find my replacement fuses and bring my boxes too.
