    thanks for this John - i can sense victory is close...

    I dismantled the connector half way today, but then I got stuck at the yellow locking clips... I couldn't figure out how to undo them without breaking something. My problem is that I break stuff all the time due to being alittle heavy handed, and so I stepped away. I can have another go though.

    I saw the 2 cables pinned down with some sort of a locking mechanism. Would you want me to tighten these or move the cabling upwards alittle more? Could you expand on that bit (paragraph 4) alittle more please?

    I'll go and un-twist the connector for now....

    cheers

    Is this the paragraph about cleaning or the next one about testing?

    okay un-twisted the black connector - lets have some fun!

    I was referring to the bit where you were explaining what I should do once I've dismantled the connector. I didn't fully understand. In all honesty, the clips look clean - i think somethings just moved about alittle somewhere along the lines

    once i've dismantled it - what should i do?

    also, can i use Mr Muscle on the connector? It says that it works on metals.....or how about a thin 3-in-1 multi-purpose oil?

    thanks

    I can't figure out how to get this yellow lock out without snapping the whole thing

    You could use Mr Muscle or Killit Bang but you would then need to dry and lubricate to stop further corrosion, but do not use 3in1 use WD40.

    If you dismantle the plug (bearing in mind I have not done this on one of these) I imagine you will find the two wires crimped onto to small right angle pieces of metal the end away from the wires being formed into a small tubes that when in use slides over the air bag connector pins. The idea is to close those tubes slightly so that when fitted they are a tighter fit on the air bag pins.

    If you fit the connector to the air bag away from the car if you check on the ends of the wires with your meter if the connector is working the readings will be as I explained if not you will get an open circuit reading (the same as you get with your meter turned on but the probes not connected to each other.

    I can't get that yellow clip lock, so I stuck a thin screw driver in there and pushed it in further but it didn't move.

    Anyway, I tested it as you stated above and the figures wouldn't settle but I did see them go between 02.8 to 05.0

    For the sake of a tenner, I think I'll just get the connectors tomorrow and see how I get on with them.

    Shall I snap this connector open just to see it open? Might aswell ey?

    If you can get replacements you have nothing to loose and knowledge to gain.

    When test with the meter on the low ohms range (200) you need to have good connections to get a steady reading, holding the wires and probes together with your fingers will help get a steady reading. This will not affect the validity of the reading.

    i started using my fingers just now....

    So I dismantled the whole connector and it looked really interesting. I didnt use Mr Sheen or anything else, I just stuck a toothpick in and out of it pretty aggressively and then I tested it. The measurements went alot lower. At one point, it seemed like it settled on around 01.8, but it was still too crazy, no matter how many fingers i used and how long i waited. It kept on fluctuating. Clearly there's a party going on in those connectors! :D

    I'll get the new ones tomorrow along with the scotch locks and hopefully, we should be good to go.

    I should have a replacement battery by Thursday aswell so it should all come together nicely :)

    I'll then have to look towards tackling the issue of rust on the underside of this car. The last guy must have tried to go swimming with it - who knows, wouldn't put anything past him! hehehe

    Good luck with the new connectors. If you hold the probes firmly together on your meter does the reading settle or does it still lump around.

    I just re-tested it with my fingers and i found that when the black connector was plugged in with both connectors locked into the airbag, the reading settled to 00.5 to 00.6 - which is what it was when i tested the nodes without any plastic tubing on them.

    Does this mean that connectors have now been cleaned and healed?

    With the scotch locks if you have not used them before you leave the insulation on the wires to fit them.

    just watched a youtube video on scotch locks...they look pretty user friendly but they look pretty bulky.... will there be enough space behind the airbag for them to fit in snug? Unsure if there is much space in that little compartment in which the airbag fits...

    This sounds like the connectors are now making contact but the little gold deactivating strips are not being pushed away from the pins, the reason for the reading being the same as without the plastic tube. (deactivated). I would expect the reading to be in the 02.0 to 03.0 range. Have you got the connector in the correct way round "turned 180 degrees" I do not Know if this is possible but is a possibility.

    They are quite small there should be a reasonable amount of room for them.

    mate you're a genius!

    okay - so i went back to the assembly and put the connector back together...it looked really messy as I sort of destroyed it earlier - but anyway - it all fitted back together. I then plugged it into the socket, took the reading with my fingers assisting and it came out with a whopping 02.8 flush - very steady - did move to 02.9 once or twice.

    I think this means it's sorted no?

    but the connector looks like it's in tatters :(

    I could always clean it up and stick it back together with some clips to hold it all together maybe? But its been weakened so may aswell just put this down to an experience/experiment and get the ones for £10 tomorrow?

    what ya reckon?

    I would get the £10 one for safety but at leased you know now how it works and that it works.

    Do the same test with the "new" connector before fitting to the car and all should be well.

    You will also have the satisfaction of knowing you can work on the Prius yourself even the complicated electronics but always work through one step at a time eliminating each section till what your left with is the fault. The art of fault finding. This will giving you confidence to carry out other jobs and get to know and enjoy your Prius.

    yes definitely John - thank you - you're a real star!

    Okay, so I went outside and fitted the airbag (loosely) and then the battery (with jumper leads), and the airbag red light was still on, but the red triangle light had gone.... could the other connector need cleaning aswell maybe?

    Or maybe it was because the airbag hadn't been fully fitted in with screws and it detected this?

    unsure - but so far, so good - atleast that red triangle has gone!

    I do definitely feel more confident now but I would always prefer to run things past you first :)

    This all reminds me of the days when I was about to become an electrician - but the exams sort of put me off, but I still learnt a fair bit about different types of circuits/cabling.

    I'll let you know how it goes with the new connectors

    thanks John :)

    You will need to clear the codes with Techstream then try again.

    okey dokey - will do this properly once I've connected both connectors with those scotch locks. Ours will look much neater than how it is currently.

    Hopefully that light is nothing to be concerned about

    thanks again John and have a good night :)
