Hello..

I'm certainly not the first to have this problem from this forum, I found you all by accident and have enjoyed reading and digesting your thoughts, views and advice.
I'll bring you all up to speed, short version, but you may want to get a coffee now...

Junior buys Stilo 1.6 16v on a 53 plate......car has done 136.000 miles is clean and tidy and has beenwell looked after. usual issues with this for its age shocks all round knackered, front tracking n/s well off, rear bushes probably non existant from sound and feel, front skuttle drains blocked, thermostat knackered, rear dampers knackered, stop laughing i'm not finished yet, drivers door panel buttons not working, drivers seatbelt torn, gear stick knob broken, and yes that dreaded airbag light. Not bad for 500 quid.

I have as i type only the bushes and wishbones to replace all else has been repaired to MOT standard by yours truly, except the light. Now this is were wee get to it. I have an Autel MD 802 does the job on telling me what i need to know on hundreds of cars including juniors. so far we have done 4 complete scans, tests, updated the unit as i've only just bought it and re done the tests again. heres what we got.

photo 1 shows some issue with onboard computer and airbag system to be all ok.....

photo 2 shoe=ws the code in more detail and a description of the code.

photo 3 again a fault found with instrumnet panel

photo 4 shows the live data stream showing clearly the airbag light is on yet system is ok....

I have also added the live data printout for the techies to look at nothing i can see stands out hopefully i'm wrong.

So far i have removed both seats checked wiring on both looms under each seat and all connectors, i did disconnect the battery as per guidelines. i have traced as best as possible the under carpet looms from the front to ecu for airbags no breaks or cracks. Steering wheel hauled off and contacts examined no issues there.

so simple questions why the light and what have i missed???? i'm guessing this is not the usual fault having trawled the forum. I am now in your hands.......

kind regards and thanks

Steve

Your previous post on the other thread suggested that you were checking rear seat airbag wiring. The code shown on your scanner (2F-2P-2L-2T-I-C) suggests you dont have rear seat airbags. Have you connected to the correct version of the airbag ECU?

Which airbag light(s) is showing?

If you add your location to your profile, someone close to you with MES may offer to scan the codes for you.

Hello again. in the previous post i/we had and still are concentrating on the front wiring looms under the seat, and front areas, the majority of issues seem to stem from the connectors under the passenger sest for one reason or another. we have not begun to look at rears as yet, I was beginning to run out of clues and rather stumble on any further i thought i would ask for assistance. I had no idea that the pass/no fault code 2F-2P-2L-2T-I-C refers to non existant bags, or not connected bags. We tried the local garage, they seemed more keen on the it hasnt been in to us before for a service or such like than to offer any advice or guidance, the mighty dollar rules our world.

The Ecu point. The Autel is OBD II this connects to the same port near the fuse box as the MES adapter, i'm looking at the Vagcom 409 or kkl. The Autel whilst not specific like the MES uses pre loaded data to run scans on all EMU and ECU devices fitted to the car, i'm a little shaky here having looked and downloaded the MES software i'd have to compare the two to determine the difference in reported info, looking at the screenshots of the MES i'd have to say its more in depth.

The photo below shows airbag light on dashboard with key at MAR position.


thanks for reply

Steve

i'll up date profile etc i'm in sunny Aldershot Hampshire gu12 4bh

2F-2P-2L-2T-I-C is not a fault code, it indicates which, and how many, airbag/pyrotechinc devices/exclusion switches/OCS are fitted to the car. There are 6 different permutations of these devices fitted to the Stlo and 6 different versions of the airbag ECU. MES has a menu that allows you to select the correct ECU according which devices are fitted to the car.

2F = 2 Front airbags
2P = Seat Belt Pretensioners (driver + passenger)
2L = 2 Side airbags
2T = 2 Curtain airbags
I = Switch to disable passenger Airbag
S = Front Seat Passenger detection system (OCS)
C = Switch to disable rear seat airbags

It's going to be very difficult to diagnose the problem without a fault code. It could even be a fault with the instrument cluster that's keeping the warning light on.

Just a thought.....do you know, or is there any evidence, that the car's been involved in a crash? Perhaps the light stays on if crash data hasn't been deleted from the ECU even though a device that was activated during a crash has been replaced.

Thank you for explaining the codes that the autel spat out. in answer to your questions. i the autel screen, I have seen no fault codes, these show up as red in te autel screen diagnostics, it was my confussion that led me to say what has already been shown on the autel was a fault code, it also demonstrates to me and all newbies how easy it is to get confused without the correct information. it never crossed my mind that these numbers and letters may refer to the components actually installed.

as for the codes it has spat out non, as far as the autel is concerened all is tickerty boo. it knows the warning light is on, i noticed this from the live data i collected i believe it shows this on the text file i uploaded, but what is causing this is the mystery.

has the car been pranged, no it hasnt, i thoroughly checked the front, boot and mid sections there is no tell tale sign of respray, welding or old on new parts, having been to a few RTC's in my time i know some of the things to look at as far as body work goes. it has however been scraped down both sides, not sufficiently to fire the bags i would say but i cant swear to this, certainly no codes have been left if indeed bags have been replaced all codes have been cleared, there is nothing stored or pending in memory

I agree this may be instrumentation, i have also been told about a D4 connection?? under the fuses does this make any sense? it had been jet washed before we drove it away the fault happened on the way home and has been there ever since.

Steve

None of the airbag wiring goes via the D4 connector.

I read your faults.txt file. It's very strange that your Autel says there is an airbag fault but doesn't give a fault code for it. According to the MES website, you can read airbag fault codes with the free version. I would be inclined to get a modified KKL cable (or modify an ordinary one yourself) and try that to see if it gives a code.

You may be able to test if the instrument cluster is keeping the light on by disconnecting the signal wire from pin 8 of connector A on the airbag ECU. It's difficult to remove individual terminals from the plastic housing without damaging them so I would disconnect the complete connector. There are 2 connectors on the ECU, 24 pins and 32 pins, each are held in with lever type engagement/locking clips. Connector A is the smaller 24 pin one.

Disconnect the battery, wait 20 minutes then disconnect the connector. Reconnect the battery and switch the ignition on. If the warning light is still on, then it must be the instrument cluster. Switch the ignition off, disconnect the battery, wait 20 minutes then reconnect the connector. When you switch the ignition back on, there may be lots of stored fault codes because the connector was disconnected. They can be erased.

The ECU (M60) is below the heater. The connectors are accessible from the driver's footwell behind the center console side panel.
.

I am glad you agree. I was puzzled why the autel recognises the light is on but gives no fault code as we've discussed. The only way now is too pop the connector as suggested.

Just been out to have a look under foot well and it is exactly as in your picture. i've decided to get one of those cables, Vagcom49 as soon as it arrives i'll run the MES software and compare notes so too speak.
as fro the autel i'll give it run and do a review, quite honestly it looks like the MES beats it hands down, certainly for fiat specific, current updates allow the autel to scan nearly all models Asian, european and american 46 manufactures and all vehicles in each manufacturers range.

ill keep you posted

Thanks

Steve

My dash light was on not long ago after sorting the errors on mes I found out the it was a loose connection on the harness itself under the passanger seat if you trace the wires under your seat and give the part of the harness that goes under the catpets a quick waggle your light might turn off like mine just curious has yours been fitted with a ocs emulator at all

Well here we go. Disconnected battery and wiated 30 mins. Removed 24 pin connector from ECU. Re attached battery and turnd ignition on. The gremlins remain......Ran a scan of te entire system and safety system on its own this is what we got.
picuters 1 through 4 show varying faults found. picture 5 the Red gremlin. Seem we may have a fault with in the dsh insruments, i will dtrip out at some point over next few days and investigate further,whilst i'm at that i will also check the looms under the front seats.

Thanks Al80 i will give that ago as well as i am fiddling around with the dash panel and instruments..

Steve

Shame you live abit far away buddy I have a set of standard clocks out of my car when I fitted the abarth ones. Fully working no faults

Whre r u then Aj??

Stoke-on-trent mate

know it well run the marathon..........
