Airbag Warning Message And Light

[fieldinsb]

Latest on the T180 is that I have got all the final bits, and have just fitted the new airbag computer module (the box that controls the airbag system). However, I cannot get the warning message and airbag light to switch off on the dash. I wondered if someone (anchorman, partsking?) might be able to shed some light. I have tried taking the Battery off for half an hour and then reconnecting it but that does not seem to have worked. Can anyone help?

Why was the light on in the first place? What happened to it? are there any codes stored? sorry for so many questions but I dont know the original problem

Hi Kingo,

Thanks for getting back to me. The light was on because the car was involved in an accident where the airbags were deployed. The affected parts (drivers airbag, passenger airbag, driver knee airbag, driver seatbelt pretensioner, passenger seatbelt pretensioner and airbag module control unit) have all been replaced. However the dash still comes up saying to check the airbag system.

I dont know if there are any codes stored. Is the a possibility? If so, how can they be erased?

Cheers, Simon

Sorry for delay I have been on lates this week (no bothy not running late trains, working late shifts [although some trains on the late shift did run late])

Anyroad up! I believe you will indeed have to cancel the fault codes to take the lights off. You can see Mr T or some garages will have a suitable OBD11 reader which will also cancel them. You can buy your own for future use for less than £30 delivered and they are very easy to use;

The codes are shown/stored in three ways, a light which shows momentary is indicating a low risk fault, alight that shows permanently to show a fault that needs attention and a light that flashes to show a fault indicating the car should not be moved or has defaulted to limp home or completely shut down.

Replacing all the components as you have done will not erase the codes from the ECU.

I hope this helps.

Thanks Anchorman, One other thing not on your list, but could be tested for, is the air bag, spiral cable, located behind the steering wheel. I have known these go faulty after air bag deployment

fantastic, thanks anchorman and partsking!! I will make my endevours to have the faults cleared out and see what happens.

Partsking - could you give me a quote for the airbag spiral cable and also what the part number is please? I think I know the bit that you mean; the bit having a cable that connects onto the airbag itself...

Cheers, Simon

Simon,

You should be able to read out the DTCs (fault codes) yourself, with a bit of wire attached to the vehicles diagnostic connector (see attachment).

If you try it and are successful, let me know what the codes displayed are and I can tell you what they mean.

Some people call the "spiral cable" a rotary coupler. I don't know about Toyota, but certainly Nedflander's rotary coupler connectors used to have a shorting bar built into them. It was to help make the airbag squib "safer" when the connector was disconnected. Unfortunately if the connector wasn't quite home by a tiny amount the shorting bar would still short out the connector pins, causing the airbag light to come on. If (big if) the Toyota connectors are similar, this may be all that the problem is and the cable may be fine. You should be able to check the continuity of the old cable with a ohmmeter (DVM on ohms).

........are you trying to say the RAV has the same bits as a LRFL?

........are you trying to say the RAV has the same bits as a LRFL?

If it's true we're all in trouble!

........are you trying to say the RAV has the same bits as a LRFL?

Nah, only in the sense that they both have airbags. If the connector arrangement is similar, I would expect the RAV one to work properly :D

fieldinsb: Simon, I cant PM you, your inbox is full

Can you PM the chassis number of your beast please, I need it to price your spiral cable, believe it or not, there are a few different types

Hi Kingo,

Inbox has been cleared out and I have PM'd you...

Look forward to hearing from you!!

Hi...

I tried to open the attached pdf file on the diagnostic socket... when I double click it to open thr pdf it tells me I am not logged in (I was/am)? I tried logging out and in again, but still no joy! I have a Rav 4.1 (no OBD-II) so was trying to obtain info on the diagnostic socket procedures.... mine is a 3dr Rav, so Bothy may have some inf. here? :)

Regards... Dave

Works for me Dave - but then I posted it - perhaps it is some odd file permission thing.

Anyway, this is 4.3 specific - sorry! :)
