Has anyone successfully pulled codes from a AIRBAG light?

There are no OBD codes for the airbag light. The fault can only be seen with SD-1.

I had mine cleared using an SD-1

Hi Eric

the most common thing is the resistance of the airbag itself goes out of spec

I cant remember off the top of my head but if you measure across the terminals it should be 10-ohms resistance. If it is not there the light comes on.

Disconnect batter before checking

 

Oh sorry I misunderstood Try to pull the codes I have done it many times on other cars pretty simple if it works. I use a SRS reader on most newer cars. Never did my 355

 

Eric,

If you look at the image I posted above, that is a screen shot of the sd2 air bag fault unit from my cars diagnosis.

You'll note that the codes at the top line up with the code descriptions you posted from the WSM. The WSM is talking about seeing the codes in the SD2 and working with that screen to clear them.

I would take the car to a facility with an sd2 and see if they will check the codes and clear them for you. I had it done for free and the light has not come back on in over a year.

 

It is a Ferrari proprietary system but indi shops can buy it also. Check your local shops to see if they have it.

 

You can even ground an OBD2 and erase codes its just a ground to said terminal

Give it a go just make sure it's the correct terminal

 

FYI, other off brand tools are out there that do work for Ferrari other than SDx...

It's possible an independant shop would have something.

 

I was told this company was developing one for personal use for $5k

A constantly ON light can also mean a fried airbag module. Mid 90's Ferrari's and some other vehicles are prone to airbag ECU failure if the voltage drops too low during cranking, as the airbag ECU is in the process of charging up a large internal capacitor to fire the airbags if you lose the battery in a crash. A good habit to adopt when starting the car (355s, 456s, 550s, 575s) is turn the key to ON, but not yet to start. Wait a good 20 seconds or so for the airbag and any other lamps to turn off before cranking the engine. If you suspect your battery is low, then don't even try cranking without either charging it or applying a jumper battery. Replacing the airbag ECU is not cheap. I know!

 

We actially have a scanner that we use in the shop for quick jobs and clearing codes when more sophisticated disgnostics aren't needed, it gets into ALL MODULES on ALL CARS , best part , we only paid $299.00 for it. I have never been let down by it, there have been times when my best scanners will not communicate and this particular scanner will. Too bad eric c told me my comments are not welcome, i'd share the name of it otherwise.

John, do you think it's possible for you to post some merit and purpose for being here? If you have nothing to contribute, please go away.

Thank you.

 

Geez, dude just cough up the name already.

 

Sd1/2 or the Leonardo are the only tools as far as I know that will pull codes from a Ferrari for the aigbag ecu.

Generic scan tools may give you an engine code from 1 ecu, but not the other. You could have a fault stored in the slave ecu that trips the light, but you will not be able to read or clear the code.

Some generic scan tools also interpret the information incorrectly, which can send you on a wild goose chase, costing you money and time.

Airbag systems are almost all manufacturer specific. In order to correctly read, repair and clear the faults, you need to have the correct scan tool and soft wear, and that in no way shape or form costs $299.00 for something that is even remotely reliable.

Yes I have a cheapo scan tool that will get into almost anything. Would I trust what it tells me? Not on your life. That scan tool is used only to reset oil service indicators, and I think I paid $299 bucks just for that.

 

These are good bang for the buck for air bag and srs stuff in that price range that has been good to me, nothing is perfect

No where in the forum rules does it say you can only , or need , post useful info.And i did post useful info , i stated threre is a simple unidirectional scan tool out there that will accees the airbag module for cheap ( i judt didnt day which one, condider it a trade secret)

A trade secret for a generic scan tool? Really John...

Whats with the "tude"?

 

Bob , "the tude" has to do with eric c having no sense of humor , telling me my comments about something , i dont rember what, were unwelcome , what he didnt consider was the fact that i now hold the answer to his question .
Daverocks says i never post snything useful, bob , i remember i gave you some useful info about that nifty little infrared temp tool when you were dealing with your header problem.

Bob when they cleared your airbag code where were they plugged in. To the standard obd2 port or the airbag cable under the pass footrest. Thanks
