Help Please Cdl Still Not Working??

Having had fitted brand new central diff lock actuator by a mechanic. Thank you so much Dan. The mechanic told me my centre diff lock was now working! On return to my property were the environment is more than suitable to check out my new found traction I get stuck, I flick the CDL switch and sit back with smug confidence while I still remain stuck. I ask my wife as it is raining heavily to investigate which wheels were spinning. After a lot of bending and staring at the 4 corners of the 80 she came over to my window and declares that the rear left is spinning on its own. “No” I replied “go and look again” as it now needed 2 wheels, one on each axel to stop us, as the CDL “is working”. “One wheel spinning” she reported again. “s*** ****” I said. I confirm my suspicions by looking at the dash no CDL light no ABS light.

Question, I am now little frustrated what next needs to be investigated? On ringing the mechanic he tells me that he thought it was working but he only investigated this by putting his finger over the top to feel if it was operating???

I would very much appreciate some advice here as the ground is getting very slippery now and I am totally reliant on the lockers working especially when the weather gets worse or I will be having to get in and out by tractor.

I can't help you but I'll give you a free BUMP
Good luck
Dan

The position indicator switch may not be working. That would prevent the lights from coming on. I do not remember if the center will still lock if the switch is not working and just not show it's locked. Have you installed the CDL switch as well?

Hi Dan,

Good to here from you and I think good evening. Well it is along story, as I have no hard standing or cover so unfortunately I can not really do much my self over the winter months here, as its very muddy so I have to use a local garage. I was a little suspicious when I was told that the CDL switch was caput but just accepted their word for it I guess I could have tested it my self. When I presented them with the parts actuator and CDL switch nothing was said until I was told I could pick up the vehicle.

I was told CDL is now working, we did not mean that switch (CDL switch) we meant the switch on the transfer box that signals to the front and rear axles in order to allow them the axle locks to go on. This is because the front and rear lockers are not operating but when the switch is shorted out the axle lockers then work, and this is the switch they want.

Of cause as I have said the CDL is not working, which seems to confuse them but I think that they had not tested for this properly. I then trek to the nearest Toyota dealership in Carmarthen. I guessed correctly that I would come away more confused than before as I was told there are 3 switches on the transfer box and which one did I want. He was not impressed with my explanation of its use and could not help me and told me to come back when I did know. I felt quite stupid at this point and still do as I could have come armed with the millions of previous post from this forum. I was given a printed diagram of various electrical components on the transfer box which I will discuss with the mechanic tomorrow.

I would greatly appreciate your advice here as it is almost a case of the blind leading the blind. What is the correct name or part number it would hopefully get things going. The only thing I dread is that some other more serious mechanical problem exists, I gues I am just geting paranoid.

4 beers or is it 5, I had beter get in training as we could have a good eveving on 4 pints apiece. I would need a lif home from our frend from Moscow above.

The most likely candidate is 84222-12010

The switch I sent you was for the instrument panel and it will allow you to lock the center without shifting the transferbox into low range. I thought that was what you were in need of as oppsed to one of the indicator switches on the transfer box proper. As Mr Bernrd Shaw once observed the English and the Americans are two peoples separated by a common language....:whoops:

I would be most happy to be overthere with you and your palls Dan, seperated by our common language or not, it is what is in a mans heart that counts. That s by me.

There was no mistake I asked you for what I got I think things got mixed up here between verios mechanics and my self you know the sort of thing one guy tells one guy and so on, most probably the person giving me the origional order had not even put his head under the ramp, its no ones falt just one of those things at least I have 2 CDL one a nice shiny new switch to show off.

Here is a link to the center diff indicator, On post three Raven Tai has a pic of where the switch is located on the differential. I believe the thread tells how to test the switch.
In case not, I pulled the switch and tried pushing the ball at the end in while the truck was in four low. Wife sitting in front seat to watch dash and there was nothing. I used a paper clip to short across the electrical connector and the dash light lit, New switch on order.

You might be able to eliminate or zero in on this switch if you test it.
Good luch
Steven
I hope the link works, If not search under (Center diff indicator) look for Raven tai's post with pic and advise, its what I used

locuito thanks for that. The thing is if the switch is replaced, can it affect the CDL i.e. if the switch is naff does it stop the CDL from working or is it merely a communicator enabling the FF & RR locks to activate?

My center diff still engages even though the indicator switch is bad, I can hear the center diff engage and she drives differantly. I believe the center diff indicator switch is just for communication for the center diff. I'm lockerless so I do not know the FF&RR answer, just the center diff on my rig.

(cruiserdan The position indicator switch may not be working. That would prevent the lights from coming on. I do not remember if the center will still lock if the switch is not working and just not show it's locked. Have you installed the CDL switch as well? )

I am a total newb and I only posted a link on how to test the center diff indicator switch. I really don't know any more than what people here have written or what I have done so far myself. IIRC Raven Tai's posts were great in helping me narrow it down to the center diff indicator. I started looking into this as I had no indicator lights on my dash for 4 low.
Good luck, If you have a second center diff lock botton I am sure you could sell it, I read alot of interest in doing this mod with the 7 pin.

Thanks loquito,
I guess I have a number of problems with my centre diff lock, I think that the switch that I have know ordered will only work if the CDL operates and in its self has no effect on the CDL its self, we shall see. I do know that when I flick CDL switch I can here a clicking sound on the Right Kick panel, I also get the same clicking when going into low box. I have a strong feeling this will run and run until every thing is tried. I shall likely be replacing things bit by bit in a suck it and see sort of way.

I wish they had a spell check on this as I have continually to go back and forth to word as my spelling is crap I am a bit dyslexic.

Don't worry about the spelling, when i post I have usually been up for a long time and so far no one has called me on my spelling
I would have someone engage 4 low while I was under the side of the truck to see if you can hear the little electric motor engage the center diff. It can be done with the engine OFF, in nutral, when you drop the shifter into low you should here the motor whine. THOUGH I do not know now that the CDL switch is installed. (I don't have one yet)maybe the proceedure is differant.
IIRC there is a way to test the electric motor with a 9 volt battery, you may be able to eliminate the CDL indicator switch and the electric motor by doing a couple easy tests.

Keep in mind I have done very little to either of the two LC's that I have owned. Most everything I mention has been posted by experianced folks and I have just plagerized the info.

It's getting later in the morning now so you should be getting all sorts of expert advise here real soon.

Check the previous threads, you may at least be able to test the two areas addressed above, at least two less things to ponder in your search if you do the tests.
Good luck, I hope you fix it

(when I flick CDL switch I can here a clicking sound on the Right Kick panel,)

I believe there is a relay in the kick panel, you might be able to at least eliminate that as a problem. . Others will tell you one way or another.

Have you eliminated any of the parts yet, Are you using a factory service manual(care of C-Dan) ?They really help.
Good luck.

No unfortunatly I do not have a FSM as yet, I do not know as to wether Dan can get UK FSMS for
1994 HDJ 1HD - T I have not asked him I will tell you this though I have just driven the 20 miles into town for the switch and it cost £61.66 amiazing.

Dan I think I shall have to start an account with you. Looking at my Euro based Landcruiser chat site site you could set up busines with the UK because prices herre are fritening.

Hi,
well the CDL is still not working. I have flicked the CDL switch and can defiantly here the motor spinning also the same when engaging low ratio. I have installed a new switch, the rear most one on the transfer box I am not sure of its function. I believe there are 2 other switches that are similar not sure where or there function as I have no FSM.

I am a bit lost as to what to do next.

There are 3 switches on the case, the two towards the rear are the low range indicator, and the neutral indicator. The other switch is the one you want, it's towards the front of the t-case, on top of the forward extension housing (the front driveshaft bolts on there).

If a new center diff actuator was installed, you should still get one front and one rear tire moving... even if the center diff lock indicator switch is bad. I'm placing my bet on the actuator motor being off index. Remove the actuator, there will be a small output gear remaining in the t-case housing, turn the gear by hand one way or the other to engage the center diff (keep in mind you won't be able to see this)... the best way to tell is to watch for the center diff light on the dash.... so install a new switch while you are down there for good measure. Now place the t-case in low range, this should index the actuator to the diff lock position.... install, things should(?) now work properly.

bjowett thank you very much for the information, that gives me something to aim for I will have to ask Dan about a FSM as it is useless here with out one, its a case of the blind leading the blind, I had no idea until recently there were 3 switches I had initialy bought the correct one (Is the great man ever wrong) but when I tried fitting it of course it would not fit, so I returned and swoped it for the one I did fit which appears to be the nuetral indicator it was nackered (broken) so no loss only time and a bit of stress. Thanks again every one it may be a short while tilll I get back on this as my Mrs is going away in the 80 for a short while leaving me with the dog and a miss firing tractor.
