Airbag ECU removal.

[2Damnsly Andy]

Hi Guys,

So a quick question. I have read up no how to disable the airbag warning lights with the use of resistors etc but as I don't have the original seats in the car, the passenger airbag has been removed and only the drivers one left if I take the airbag ecu out will there be a risk of the drivers one deploying? I'm guessing that there wouldn't be as there is no electrical current to it so it would effectively be disconnected. The steering wheel is going to be changed in the next few months anyway.

Any thoughts,. suggestions, tips or ideas?

Thanks

No there is no chance it would deploy the airbag with the ecu disconnected. I removed all the airbags on mine along with the ecu and all the wiring too. Unless your 100% confident with wiring it's probably not what you want to be doing though as I didn't have any wiring diagrams available, it was all done on gut feeling. I do that sort of stuff day in, day out so felt comfortable enough to do it.

Not fussed about the wiring but I know where the airbag ecu is hence the fact I have seen someone else in their build thread remove it and as I am due an MOT next week I need the airbag lights off, just seems to be the sensible idea.

My race car passed its MoT this week with the air bag light on.

I don't think they have brought in the new rules anyway yet.

Mine passed 2 week ago with light on

The mot law is in force about warning lights, so you guys must've been lucky or have a friendly tester. Just take the clocks out and put some black tape over the light. That's easy enough to do.

Assuming it's a ph2? Can't quite make it out in your avatar.

Air bag warning light still isn't in force. The "second set" of new reasons for rejection are still not available on the system.

I had a friendly mot station decat ect ect

I didn't totally legit.

PH1 fella, think I'll just do the airbag ecu, I'll see how tricky it looks to get too.

 

[danh90]

Easy to get to just take centre console out the bit around gearstick and it's there mate

Does removing the ecu definitely put the light on in a phase 2?

 

[mark123]

I've removed mine and I still have the light.

Yes it does. You need to have the network reprogrammed via clip ideally. Mick does it very cheap if you did need it doing

and you need to keep the airbag ecu as the light will come on once it's removed (I think).

You might be right mate. Otherwise the network will see a break in the CAN circuit

 

[2Damnsly Andy]

Surely if there is no ecu it won't be looking for it? Otherwise pointless removing it.

It will assume there is a break in the network and flag up a problem

 

[Sean6545]

Air bag ecu is one of the 'main' computers in the network. It won't be able to be removed easily.

Ok so to clarify....remove clocks and take bulb out as everything else won't work. Does the service light need to be out as well?

 

[Cup_Phil]

It isn't a bulb - it's soldered LED's on the circuit board

You have to take clocks out - dismantle them (take front off, pull the needles off taking note of where they were so they aren't inaccurate when back together, then tape over the lights and re-assemble)

 

[2Damnsly Andy]

This is turning into a ballache.

 

[Cup_Phil]

Yup

 

[Sean6545]

Yep, you probably won't be able to remove the bulb though as its a smd. Abit of tape to cover the smd will be fine.

On a PH1, remove the airbag ecu, and associated wiring to the plug. airbag light then goes out. There is about half a dozen wires going up to main loom. i cut these back, and no more airbag light.

 

[Jonny1*2]

The level of CAN changed on the ph2 mate. I don't think you can do the same unfortunately
