Resetting service warning lights

Airbags are (were developed for) Yanks who refuse(d) to use seat belts.

I'm not the one claiming the residual electrical energy will set them off, why don' t you explain how much and from where?

There is a difference between a faulty system and one being used as intended. Suppose the fault caused the airbag to go off while there was a child and seat there?

Design covers faults that they can predict, not ones they can't. So a safety critical system may identify that there is a fault but may not be able to safely "fix" it. Maybe that's why the law requires you to get it checked and fixed? Maybe its the law being an ass?

Its clear that you don't have a clue! But lets not let that stop you from content free posts. Are you huge's alter ego?

a quick google says that 3-4 volts can set one off.

How many joules? Where from?

and a code will tell you which item needs "servicing".

Sshh, don't tell dennis.

Who gives a s*it?

apologies, that was meant for the question above.

Who gives a s*it?

Recently it was as simple as the reader telling me to change a specific sensor. 10 minutes to put out a light. It took longer to source the component.

Your point?

No problem, it did seem out of character. Apologies for an abrupt reply below.

That's a bit rich, how about telling us the legislation that makes it illegal to drive a car with the ABS light disabled.

It's a safety critical system, clearing a fault code by plugging in a diagnostic tool (either the official one or an aftermarket one) does not stop the constant checking of system integrity. That unchanged functionality is by specific design.

By clearing a fault code you do not make the system unstable and non compliant with any type approval or Construction and Use legislation.

If the vehicle undergoes another ignition off followed by an ignition on event it will initiate an airbag check at which point the airbag fault light and a fault code will be set again.

I know for certain some airbag ECU's plus some ABS ECU's are hard coded with separate PROM's or if integrated with the processor they used an on chip OTP or masked PROM area of memory. In the case of the former nothing you do short of aggressively removing some very thick conformal coating, desoldering the PROM, reverse engineering and substituting new firmware with the correct checksum can ever alter the configuration of that ECU. In the case of the latter it will be effectively impossible.

Every airbag related connector in my experience is colour coded, with two means of pin backout prevention, with a means of ensuring positive engagement and a means of preventing connector separation by tugging on the wiring or the two halves of the connector. The manufacturers take this subject very seriously.

But despite that it's extremely easy to set an airbag fault code if you perform work on any part of the airbag system without suitable upfront actions, those might just be battery disconnection but could also include the separation of specific electrical connectors. Removing a steering wheel or a seat without those precautions can very easily set an airbag fault light and a fault code, clearing that code by recognised means DOES NOT make the vehicle unsafe.

You claim 3-4 volts will detonate an airbag but its not the volts that does it but, you don't give a s*it as long as you can give an answer however wrong it is.

The specific details have alrteady been given in this thread even if I got the wrong section it was corrected by the following poster. Don't you read stuff that proves you wrong? must be a brexiteer, they do that all the time.
