    Hi Alan, funny thing, I have the exact same light popping up on mine!
    If you have diagnostic equipment, often that will point you in the right direction.
    It's a very easy fix, I've done this on mine several times over the last 10 years.
    Disconnecting and reconnecting the SRS yellow connectors has worked every time for me.
    1st thing is disconnect the battery whenever you are doing anything SRS related, I've heard you should wait a few mins to let the charge dissipate.
    I have a 2001 model, so your connectors may be slightly different locations.
    Under the seats you will see yellow wires and a connector, they are easy to get at, I would start there, disconnect and reconnect, I also spray some contact cleaner as well to give the contacts a clean, let them dry properly and then reconnect.
    The one that always fixes it on mine is the connector under the steering wheel behind the footwell cover.
    I take off the cover and it's easy to spot the yellow cables and connectors.
    Once you clean the one causing the problem, the fault will go away.
    It's probably just one connector, but I would do a diagnostic check and read the fault codes to see what is causing the SRS light to come on.
    Hope that helps, I'm about to go and do this on mine!
    Cheers, Pete.

    On mine it was the “clock spring” on the steering column that had gone intermittently open circuit. I could clear the fault but the next time I went around a corner, the light would come back.

    Replacing it fixed the problem.

    SRS airbag light

    Hi Pete and Ron,
    Thanks for the information, that gives me a place to start looking. I am going into work tomorrow and I will have a look on the Snap On and Carman scan tools and see what I can find. Hopefully not the clock spring but you never know with these old cars.
    Regards,
    Alan

    I did this on mine today, disconnected the battery, removed the cover under the steering wheel, the plug is easy to get at, a yellow cable with a red connector.
    I disconnected the plug, sprayed some electical contact cleaner on both sides and unplugged, re plugged a few times to make sure the contacts were clean.
    Allowed the spray to dry, reconnected the plug, reconnected the battery and the fault was gone, no need to clear the fault code, the SRS fault message was gone from the message centre.
    Took about 10 mins all up, all good!
    It could be another connector on yours, but that's all there is to it.
    Hope that helps.

    : SRS airbag light

    Hi Peter,
    I was going to give it a go today, but I thought I would re calibrate the EAS. So I took it to work, put it on the 4 post hoist, put it up, put 1st set of blocks in, let it down and enter values into the scan tool, etc. times 3, almost finished and the scan tool loses communication. So after going through the process 4 times and still not getting to finish the calibration I gave up and came home. I will tackle the SRS light first thing in the morning, then I have to go see the Doctor to see about getting some more cancer removed. So that could slow progress a little.

    Oh how annoyiong, it just wasn't your day!
    It's the small annoying things that can try your patience sometimes.
    Good luck with the docs, that doesn't sound like much fun, hope it all goes well for you.

    SRS airbag light

    Hi Folks,
    well it has been an interesting week to say the least. I had 6 biopsy's done for skin cancer on Wednesday. Doc said to call Monday to see how they go. I head off home in the P38, before I get home the engine light comes on. So Thursday when I am not too sore I plug in the scan tool and it says the LHS knock sensor is out of range and the air flow meter is also at max negative setting. So I replaced the knock sensor and cleaned the air flow meter and all was good. So today I thought I would try to reset the suspension heights. So I go to work and put it on the hoist and neither of the scan tools will talk to the P38. So I gave up and came home, and I thought I would do something constructive and replace the LHF window mechanism. So I am half way through this job and my doctor rings ( doctors don't ring with good news ) one of the biopsy's is a melanoma. He wants me in for surgery first thing Monday morning, F***. So there goes my next few weeks.
    So my question is, are there any common reasons for no communications with the scan tool. I have sprayed the OBD port and the scan tool plug with contact cleaner. And I am still chasing the air bag fault.
    I also have also a EAS fault. The vehicle is a 1995 P38 4.6, and it had EAS problems when I purchased it. So while I was working on the motor etc. I replaced the 4 air bags, as they were getting cracks in them. I also rebuilt the compressor and valve block, and made up and fitted a set of manual inflation valves. And when I got the motor going the EAS would go up and down sitting in the yard. The first time I took it for a drive it dropped down to the bump stops. I messed around with things and it seemed be working and I took it for another drive and this time it dropped the DS to the bump stops and the PS to max height. So I let it down and took it home and fitted an isolation switch and pumped it up with the manual valves. Any Ideas? I am trying to stay busy over the weekend so I don't dwell on the up coming surgery.
    I also have another fault code, speed sensor out of range and the speedo is not working, so I am not sure if all these things are connected.
    Thanks,
    Alan

    Geez Alan, it's really not your week! Sorry to hear about the diagnosis, it must be a bit of a shock for you, at least it has been caught and they can do something quickly for you.
    Wow that's a lot of faults all popping up at once, I've never had them come that thick and fast.
    What diagnostic tools are you using?
    I have a faultmate that I could not get it to talk to my PC laptop, after persisting with it, I updated the drivers on the laptop, and finally it started working.
    Not sure if that is your problem though.

    So you have had:
    Knock sensor
    Air flow meter
    Window regulator
    Airbag fault
    EAS fault
    Speed sensor
    No speedo

    Thats a lot going on at once!
    I'm wondering if it's something causing the errors, I once had dirty battery terminals that caused all sorts of weird errors i would be checking that, also the condition of the battery.
    The speed sensor and speedo failure would be related i think.
    Don't let it overwhelm you, just tackle one thing at a time.
    I'd get the diagnostic tools working as a first step, that will at least point you in the right direction.
    It's part of owning a P38, you have to keep at them sometimes.
    I usually do all the jobs during the warmer months, it's no fun underneath the car on freezing cold days.
    All the best with the docs, I hope it all goes well and is over with quickly for you.
    Cheers, Pete.

    SRS airbag light

    Hi Pete,
    yes it has been a big day today, two and a half hours on the operating table to remove a malignant melanoma and a skin graph. But I did have some success on Sunday. I pulled glove box out and cleaned the OBD port and I regained communication with the scan tool ( I have a VDO and have a Snap On one at work). I also replaced the Wabco computer behind the glove box, Just because I had one. I also cleaned the P/S air bag connector and the Fresh/ Recirc door connector while I was in there. I got it all back together just before dark and went for a drive, and I now have a speedo. And the ABS, TC and Brake lights have gone out. The car drives a lot better with a speed signal to the gearbox and Motor. So I am pretty happy with progress considering I was trying to work with bandages on both hands, right leg and foot and on my back, from previous surgery to remove skin cancers. So now I only have the SRS light and the fault with the EAS, and I also have the book symbol on the climate control computer which is no circuit to the fresh/recirc motors. But it will be a few days before I tackle any more jobs.
    Regards,
    Alan
