Hi all,

Grateful for your help, as I am quite illiterate when it comes to these kinds of things!

Was driving Tuesday night last week and - not unusual in my area - had to honk at yet another driver of the imminent danger he/she was causing. Soon after, the SRS warning light turned on and has stayed on since, whenever the ignition is on.

Was thinking it might just be a worn clock spring/spiral connector, but the stereo controls still work (haven't tried the horn since - I fear that the horn may be stuck on if I try it, as is the case for some other vehicles on other forums I've Googled), so I am suspecting something more expensive?

Was also trying to buckle something up on the front passenger seat (to stop it from rolling around on the front passenger footwell) a few minutes earlier, but if I happen to have stuffed up its pre-tensioner, you'd think the SRS light would have been on then, and not later (a few seconds after pressing the horn)?

The only other "unusual" thing I did prior to the light coming on, was scraping and blowing off white deposits on the battery terminals (should've just used baking soda and warm water) two days before that. But again, I doubt that would have caused the light to come on?

My horn pad by now is mildly folded horizontally, just below the Mitsubishi badge. Could it be the horn pad? Should be fun looking for a LS/LX horn pad these days...

Taking it to a trusty mechanic tomorrow - just wondering if any of you have a similar experience, and whether I should tell the mechanic to start focusing around the steering wheel area (given what I have described above).

P.S.: @Administrator John...may have to ask you about that 30% off discount if it starts to get expensive, especially if you still have it!

My sons 380 just did exactly that..

It turns out its the airbag connector came loose under the drivers seat...

You need a MUT3 to clear the fault....

Never start the car with an airbag disconnected...it needs a MUT3 to clear it.


So if you have a dodgey connection on your steering wheel airbag even after fixing it it needs dealer interbention.

I would always take it to a dealer if i didn't have a MUT3...its a primary safety item.

On my GT the guys who did the turbo install stuffed the bumper bar airbag sensor...I had to replace the airbag controller unit.

This unit is at the very front of the center console near the firewall.

Most of the car interior had to come out to get to it...it has to be replaced...a fuseable link blows in it.

Ouch. Being not so handy myself, I'd imagine it would cost me a fair bit in labour if that is indeed also the case for me!

Anyway, my mechanic first cleared the light and it did stay off for a while...but as of a few weeks ago, the light has come back on again and is staying on. I recalled him saying that it was a historical code that was cleared (by someone else) previously, but the pre-purchase inspection report did say all panels had original paint from the factory of the same age, so it could not have been a dodgy smash repair job before I started owning the car (as it would've never been in an accident beforehand)...and it has certainly not been crashed since I own it!

At the same time, I also only found out recently that the back lower cover of my steering wheel has gone completely missing! Can definitely recall feeling a cover around there when I bought the car in 2013, and nothing have broken/fall off during my ownership, except for the headlight switch recall in Sep 2014...see photos. I usually park with the front wheels in the "straight ahead" position, so it was not until the other day when I did not park this way, that I noticed the missing cover.

Thus, putting the two things together, IMHO it would not be completely unreasonable to surmise that:
- the dealer stuffed up something in my car's SRS system while they were replacing the headlight switch, triggering the SRS warning light
- the dealer simply did the minimum to address the issue (e.g. clearing the light), and did not tell me about this. Lucky for them, the light has stayed off long enough until recently.

Suppose this is indeed the case. Do you think it is too late now to report this to MMAL and request for a free fix at a (more reputable and competent) dealer?

Had a quick email exchange with that Autoexpert guy.

Hate to say this, but I reckon he is right in that it is highly unlikely that MMAL will come to the party regarding a pro-rated/free fix for something that may or may not have been caused by the dealer years ago.

Just hoping that it won't be expensive in my case...

Will keep you all posted on this.

if it clears and stays cleared then it is not a controller fault.

you really need a mechanic with a MUT3 test unit to clear it....only myself and a mitsubishi dealer have them.

it might be a genuine fault in the steering wheel assembly.

take it to a dealer mate...unless you can get to Hobart and i would be happy to help for....free....


It could be the clock spring in the steering wheel assembly making dodgey contact as you spin the wheel....simple fix if you have the parts.


just re-read your first post....its a problem in the steering wheel.....wreckers...50 bucks and you'll get the whole lot...bag...clockspring etc


disconnect battery first...wait an hour.....


DID I MENTION DISCONNECT THE BATTERY FIRST ?????????????!!!!!!!!!!!!!

Thank you John for your input and support.

The LX has been back to the mechanic since. He took it to an auto elec and the report came up with B1411 - front passenger airbag squib open? So they checked a few things around there and cleared the code, and all seemed OK. I include a pic of the report they gave me - does this mean they have a MUT3? Or just a generic scanner?

Anyway - a few weeks of all clear later, and the light is back on and is staying on again as of a few days ago. Probably the controller then?

At this point, I can take the car back to the mechanic for them to take out the dash and replace the controller etc., or I could take it to a dealer. Not sure about the former option again, because I'd hate for this issue to drag on (I am charged labour every single time, not to mention the logistical inconvenience etc. which is becoming annoying). I am also hesitant with the latter option considering what they did to my car for the recall, and the likely $$$ they will charge.

So I really hope you are not joking re: coming to Hobart. I would rather entrust my LX to someone who is likely more familiar with 380s than anyone else, and is more likely to fix it once properly at a reasonable cost...!

I just noticed something...is it overstating the obvious that that code B1411 resolves into identifying that the passengers' front air bag is disconnected?


(well it does on the galant and the pajero...)


Maybe save yourself some time....disconnect the battery
.disconnect the battery
.disconnect the battery
.disconnect the battery
.disconnect the battery
.disconnect the battery


then wait 20 minutes...

pull the glovebox insert out..it's not hard...just fiddle..

behind it is the airbag....have a sniff around ...see if everything is plugged in nice and tight.

I find after market stereo installers are the culprits if stuff has come loose.


Try the above...it certainly points to that area...

Oh...U1120 is what you get when battery is almost stuffed or the crank angle sensor is on the way out...

John - I can't say I'm much of a DIY guy to date, but a quick Youtube search suggests I should be able to mix concrete. My wife can probably help out with other lighter tasks - she wants to come along as we both love Tassie very much. We are happy to help out with any and everything really - as long as it's legal and won't break our marriage!

In terms of timing - are you OK with any day(s) between, say, July 27 and August 11? Hopefully it won't take that many days to fix. I will definitely take extreme care on certain parts of our trip to you - I don't think the half-worn RE002s fancy black ice that much! Surely I don't need snow chains?

Do you want us to pick up and/or bring you anything from the mainland? As long as it can fit a LPG 380 2-up with winter gear. Might save you postage on something not too bulky, but perhaps relatively heavy for its/their size(s). With some weeks to go, you might as well see if you can organise something, and make the most of the opportunity

Happy for us to PM/email each other in private so we can nut out the details. Probably better/easier that way too.

P.S.: FYI, the wording in the invoice suggests the mechanic and his auto electrician friend simply tested the LHF air bag circuit resistance (apparently it was OK). Definitely no aftermarket stereo (and no sign of the removal of a previous install) as far as I can tell, but I do notice an inconsistent gap in the LHF air bag dashboard cutout that was been so for some time, possibly due to heat...I'll show you what I mean in person. Then you can show me all the other things you've mentioned as well.
