Resetting service warning lights

Between us we quoted the succinct section that makes it an offence to drive any car which fails in any way to meet the construction and use regulations. This is not even confined to explicit safety regs. I am surprised at the draconian nature of this law, but law it is. Section

What we don't have is the full text of the construction and use regs and how they apply to each and every model of car, and indeed to ad hoc registered cars. I doubt if this exists as a single document, which makes it even more outrageous that breaching it is now a crime. But the section 42 has been shown. And *if* there is a regulation that says fitted airbags have to be working in a given car then driving when they are not working is undoubtedly a crime under this section.

Just because you don't understand energy doesn't mean other people don't understand ohms law.

Try this..

suppose you have an igniter that is 10 ohms and it needs 8 amps for

Now AFAIK a lot of igniters in airbags have similar specifications unless you want to post links to ones that are 4 Ohm and need 1A or something similar so they will work off 4V and explain why they would use them in a 12V system?

They don't need a book, the computer should tell them the sequences.

I think they are just trolling and I am killing this thread.

They just don't bother checking. "Does it illuminate then extinguish" is the extent of their testing.

I have and there aren't any posts.

Non-existent posts, a figment of your imagination.

Then stop replying when I say these posts don't exist.

How does your example perform with 12V?

You do talk crap.

I don't think any voltage going through a 1 Megohm resistor would fire anything.

I haven't seen you post anything useful to this thread, or indeed any other.

After not providing anything of substance to this thread, we should be grateful for small mercies.

Me too. Very handy as the module can even be left plugged in permanently, so no wondering where you put it after you last used it.

Once I was parked in a shopping centre car park and noticed an open SSID that appeared to be a wifi OBD dongle, that struck me as a good way to get your car hacked or stolen ...

From the doc noted by Huge somewhere up this overlong thread:

The inflator consists of a metal case inside of which there is a combustion chamber surrounded by a metallic tissue filter packing. In pyrotechnic inflators, this chamber contains

? In the event of a power failure due to an accident the central unit has sufficient own energy reserves to trigger the airbag. These are ensured by one or more condensers which are charged to 30 V ? 40 V by means of a cascade connection. The capacity of the condensersStudy 2 - A Test Procedure for Airbags

dennis@home explained :

The airbag capacitors are cascade charged to 30 to 40 volts, so they can continue to be able to operate, if the 12v is lost during a crash.

That ought to only be active if the ignition if off?

Correction ^^

Pot, kettle etc.
