Airbag light with Scuderia seats in standard F430

The software in the ECU is set to recognise the switch, so to keep it functional order the correct module.

My car is a 2008 F430 Spider but the modules are the same type for Berlinetta, Spider, 16M, and Scuderia - it's the airbag options fitted that determine the part number.

 

Good Day gents, hoping someone can help out here (@mwstewart or @Doug2D ?)

@LorenzoR and I both put in sport seats, they have no CPOD in them.

We ordered 216005 based on Doug's testimonial above where he says his light went out.

Lorenzo just installed it (mine's on the way) and he's got a fast blinking airbag light.

These are the only 3 ECU options.

216005 is 'without airbag disable system'.

Not exactly sure what is meant by 'airbag disable system', is that the switch in the door jamb? should we have ordered 192789? Just confused since Doug put in 216005 and he said his light went out?

Any help is greatly appreciated!!!

Thank you

The manuals refer to the switch as the "deactivation" switch, but it does sound the same. Does your car have this? If so, you may have to disconnect the switch completely. Even in the off position, the switch presents a fixed resistance to the ECU (not an open or short circuit).

Did Lorenzo power up the car without any part of the system hooked up after the installation of the new ECU (apart from the deactivation switch)? If so, this would probably latch a fault in the ECU and would require a reset (with an SD2 tool).

 

Ian, heres what i did.....To recap, i took out daytona seats and installed sport seats which dont have the seat sensor in the passenger side. In this thread someone mentioned to buy the 216005 airbag ecu which will keep airbag activated but no light so thats what i did. So i got the ecu today and with Power off to the car, switched out ecu,s plugging in 2 plugs to the new ecu. Power back on to the car. Turned key on and the airbag light came on then started flashing .....Obviously the lead under the oem seat going to the airbag is not connected to anything

 

Lorenzo, does your car have the deactivation system near the passenger door? This may be what is causing the flashing light if it is still connected? The 216005 is for cars without this switch.

Just speculation of course. Maybe the "216005" ignores any input on that pin?

Maybe Doug can tell us how his car is configured what he did?

 

Yes I do have that key switch on the door jamb. i tried it in both settings. I messaged Doug but he hasnt been around since july

 

There are only 3 airbag ecu,s. 231704 is what i took out of the car...192789 says its for comfort seats so that leaves one left,, 216005 which is what i put in

 

Sorry, I didn't realise how old @Doug2D 's post was.

Maybe try disconnecting it completely? You may still need the SD tool to reset the system though.

So what else could be different? Is the 216005 designed for cars with/without seatbelt pretensioners? Do sport seats come with harnesses rather than 3 point seatbelts?

 

Im not sure

 

does anyone know what a fast flash vs a steady on means? on my car, I have nothing connected to the COPD connector, I am running with a 231704 ECU and I have a solid light.

Lorenzo has nothing connected to the COPD and is running with 216005 and he has a fast flashing AIRBAG light


very little info here on this....so, I don't know if this applies at all, but does this make sense?

231704 - what our cars came with. has airbag disable (door jamb switch?) and COPD support (pad in the daytona seat)

192789 - has airbag disable, doesn't say anything about COPD, so am assuming it does not support it? - do we need this one? - ie has the switch, does not have a COPD

216005 - (says 'optional' for our cars, does not say optional for the SCUD), no airbag disable, doesn't say anything about COPD, so am assuming it does not support it.

not sure why it is not optional on the SCUD as it also has the switch and airbag

192789 its not clear if its copd or not

 

Part nunmber for the seat sensor is 80936700. Is there a way to cross reference it?

 

Passenger airbag disable system is the switch on the end of the dashboard.

My car has 192789. I have the disable switch and no seat occupancy sensor(US market specific). No issues for me with a seat swap.

 

It is non COPD.

 

I guess I'm stuck with the wrong ecu? Why did Doug have good luck with 216005. I'm not sure what to do now. I'm ready to rip my old seat apart for the sensor

 

Mark, did your car come with 192789 or did you put it in. You have a scud correct? Im trying to figure out what to do next Thanks

 

Another approach that I can think of is on your existing seats measure the resistance between the CPOD pins which correspond to the 1) yellow, and 2) brown and red wires on the car loom. This should provide the resistance of the CPOD sensor with an unoccupied seat.

Purchase a resistor of this value and insert it between the 1) yellow and 2) brown and red wires on your car loom. This in effect tricks your original sensor that the sensor is present and the seat is unoccupied.

 

Hi Mark, we experimented with this , however, believe it would essentially leave.the airbag permanently disabled as it would be waiting for a response from the CPOD that there is an occupant and would not receive one.

 

These are the wires coming from the seat copd and theres the meter im using. I shaved the wires to make sure im getting a good connection but Im not getting any measurement

 

For the record heres the measurement of the resistor that i have so im pretty sure my meter is ok. But i dont get a reading from the seat copd.

So I pulled the description from the ISO website, according to the description, the CPOD will turn off the passenger airbag if a child is in the seat. What I don't know is what the CPOD does if no one is in the seat which is what the resistor imitates.

Does it require the weight of an adult to activate the airbag?

This is why I prefer an ECU option, because then I know what the airbag will do. It is on unless you turn it off at the end of the dashboard.

/Meaning/Referent :
Child seat presence and orientation detection system (CPOD)
Function/description :
To indicate that the child seat or vehicle is equipped with a child seat presence and orientation detection (CPOD) system, which automatically senses the presence and orientation of a child seat placed on a passenger seat, and disables or depowers airbag deployment for that passenger seat.

 

Could it be that your ohmmeter is on the wrong scale?

Here is John's measurement:

He says 1.5 ohms in the above link, but looking at his photo, it's 1.511 Megohms (seat unoccupied).

Try measuring the resistance on the 20,000Kohm scale.

 

here's the meter I'm using and the setting at 200.. ..Also a pic of me checking a resistor

Try putting your meter on the 2,000K ohm scale. I don't know if your meter is auto-ranging.

 

OK so I put it on each setting and took pictures
