Is this the cause of my airbag warning light? (2 Viewers)

[MarkOgden]

The first time I did one....I did just that, I bought a pack of mixed resistors and started off with small values and just kept increasing the values.

I had the ignition off in between fitting each resistor and power cycled the ignition a few times after each resistor was fitted till it went out.

You could if you wanted, try the next resistor back down in size after the light has gone off, just to make sure it was the right value or the power cycling that removed the light.

Thank you

Or simply measure the resistance of the pre-tensioner?

NEVER EVER play with airbag or pretensioner wiring with the ignition on. And wait a minute after full shutdown too as any voltage spike can trigger the system. Expensive and potentially very painful if you get it wrong

MOT light bypass AIRBAG RESISTOR 100 x Mixed Ohm Trade Pack SRS tool all makes | eBay

100 Airbag bypass resistors, resistor ohm size's are 10x 1.0 ohms. 10 x 1.5 ohms. 10 x1.8 omhs. 10 x 2.2 ohms.

They are from the company I bought my resistor simulator from......that are very helpful if you contact them

Sent you a PM with images and the instructions I followed. The resistor is a 2.2ohm. The images sent and the resistor are correct for a 2010 model, so should be the same on a 2013.

Hi Wissel, after spending literally days online trying to sort the wheat from the chaff on this subject I'm hoping your images/instructions might be helpful for me. I'm swapping the bench seat and the driver's seat in my 2016 Ducato for reupholstered Ford Galaxy swivel seats. The bench seat has no seat belt warning, airbags or pretensioners fitted so that's straightforward. The drivers seat has no airbags but does have a pretensioner and seat belt warning. I've got my resistor (2.2ohms) but not clear about which of the 4 wires in the plug need to be connected to cater for no pretensioner and also what I do about the other 2 wires which I assume are the seat belt warning circuit? I'm hoping that these wires will be the same colour as the passenger seat wires you have instructions for? Any help would be greatly appreciated!

Hi Wissel and Glazier

We have the exact same issue too. Would it be possible to send us the pics/diagram too please?

Sent you a message. Welcome to the forum

I tried the resistors in this video but the light hasn't gone off. Is there a way to reset the light?

If you’ve got the right sized resistors installed on the correct wires......then after several power cycles of the ignition it should realise the fault has gone and go out.

You could try increasing the resistors or decreasing them, I have a resistor simulator that I use to determine what resistance make the light go out and then fit that size resistor. You could measure the resistance across the old pre-tensioner and fit resistors to that value too.

Make sure your battery is fully charged....sometimes a low battery doesn’t give enough power to achieve enough resistance, sounds odd I know, but I had a mates van where it would come back on when his van had been stood and the battery was low.

 

[CamperJack]

Thanks XxAnthxX. Not sure how I missed your post.

I have still got the same issue!

I have even bought a replacement seatbelt and wiring etc. Light is still on with that plugged in.

I drove 100 miles yesterday so I assume the battery is full.

Can anyone suggest anything else to try before I fail my MOT?

Possibly caused by a faulty airbag ecu then…….sounds like you might need to speak to crash data.

Can you get the codes read? Maybe a funster who lives close has the capability? Im too far away although will be at shrewsbury from friday.......
When I gave my codes to crash data they said couldnt fix, new ecu required.

 

[PG’s trips]

Try crashdata …if they can’t fix then it’s probably a new ecu. Depending on the part number late August is the first date they are giving for replacements being available.

Forgive my ignorance. What is crash data?

Sounds expensive. How much is a new ECU?

Can I remove the bulb?

No you can't remove the bulb, it needs to illuminate then go off to pass the MOT.

A few people have given the opinion that a panel van doesn't come with a seatbelt pretensioner on the passenger side and the photographed plug under the seat is always there but not connected as standard. So perhaps the fault is elsewhere??

 

[XxAnthxX]

So perhaps the fault is elsewhere??

Airbag ecu…..a known fault, especially on vans that have experienced limited use and flat batteries.

 

[PG’s trips]

Airbag ecu is about £400 fitted by Fiat dealer. Obviously less if local mechanic/diy. Not that big a job, even YouTube videos to help. Just make sure you disconnect the battery.

Thanks. This van is turning into a money pit!

Stick with it you’ll get to the bottom of it….till then find a friendly test station

It's not just this. The old p2100 fault code has come back. Occasionally the van suffers a lack of power and no amount of extra pressure on the throttle will make the ******* van get moving again. Have to wack it into massiy too low gear, rev the nuts off it and change up again.

As a result I've not really been using it or building it. It's going to have to go to the garage again. But that will have to wait for pay day.

Should have bought an old banger. No computer !

I wonder if my AA mate will have a scanning gadget capable of reading it.

Probably only get the std OBD codes, but it’s a starting point.

 

[Raul]

There is a bluetooth obd on ebay that works with obd doctor app. I have used the paid version app £5 for a month and cancelled the auto renew subscription. It has detailed info and life data. Much more than generic obd readers. The obd dongle was about 12 quid delivered.

 

[CamperJack]

Took it into a garage. They scanned it. Claim the light went out all on its own. Test drove it and no problem occured. But it's not likely if they didn't go far or fast.

Going to take it on a run and see. Not confident.

Still stuck with the airbag light. I was going to get them to fix that but as they have been unable to sort the power issue Im not confident will be able to do it.

Can anyone recommend a good garage capable of this sort of work in Cheshire?
