Ok so it could be either 1-4-12 although after looking at the back of my plug 12 has no wire going to it. I will have to try all the pins I guess
Just to clarify, if it's no.1 all I do is set multi meter to 12v-put red wire from MM to pin and black wire from MM to earth?  


Hoping to have a easier time flashing up the faults.

Hi,

I am also experiencing the same problem as bucketlover, I must be doing something wrong I have tried all the pins in the socket earthed and they either return nothing or a constant output! I have tried it with ignition off then to on, or ignition off then start the car all to the same results.

Could it be because my analogue multimeter only has dc setting of 10v or 50v (etc)?

The ABS light is always on, I do know one of the faults being the drivers side hub is from a non abs car! However I want to see what other faults there could be just in case its more than just the hub.

My port looks just like the picture of emax except its black and without the numbers but looking at the actual pins it looks very similar. It has 2 earths in the middle of the left bank.

Any help would be appreciated

The car is a 96 Shogun SWB

Ok fault codes are = 15 21 22 23 24 27  
ECU failier?
And the pin that I used to get the codes was no.8

Hello  

Drx
I would have thought that if your multi meter setting was 50v it would read ok, just at the lower end of the scale but i am not certain about that, as my electric knowledge is poor. perhaps someone with a better understanding would advise you on that. You mention fuses in your earlier posts. I think the yellow 60 Amp one powers at least some of the ABS system.  I remember another member found that this fuse was blown, however he did not find that out until he removed it as it was not apparent looking at it in situ, maybe worth checking that more thoroughly  You also mention that your abs unit maybe different this is a pic of the unit that is fitted to  a 94 pajero.

Blimey! you got the jackpot there as you can see by DPRUK's list   21, 22, 23,  24 are wheel sensor faults and 15 is more or less the same (faulty wheel speed sensor output).
27 appears as a problem on the rear differental lock circuit on the list that i have. if you don't have rear diff locking, the check fuse number 18 in the main fuse block.

I think it is unlikely that all your wheels speed sensors have gone down at the same time so i suspect you have a wiring problem or as you say an ECU problem. I would check all the wiring first, this post that covers most of that,

If that does not work, if you can lay your hands on a working ECU it may be best to replace that.   The ABS ECU lives over the O/S rear wheel inside the car.  You have to remove the trim to get to it.

See you when the headache has gone

Hi Emax,

My abs unit is indeed very different its made by "Nippon ABS LTD" a cube with all the pipes not the cylinder affair in the picture you posted. I have been doing some reading and it appears I may need to remove the valve relay before they will display, If so I havent removed it and I guess I will have to find it (I think it maybe next to my abs unit as theres like a little black fuse box)

I will have a look at the yellow 60amp fuse aswell, Could be whats preventing the errors coming through.

Thank you for helping having to debug a debugger is rather amusing

Excellent string !!!
Followed all your instructions and got a code 32 (G-sensor) I tried re-seating the connector on that and reset the system by disconnecting the battery . Code went away but on a test drive the ABS light came back on and the same code returned.

So what next ? A replacement G-sensor seems to cost about £100 and I don't want to buy one if thats not the problem !

I want to check where that plugs into the control unit but I can't find it. Does anyone have any pictures or helpful advice ?

Hello lM
Welcome to the club

I got my g sensor from mitzybitz, from memory it was £35.00. Or you could put ad in  wanted section of the club or try Fee bay for someone who is breaking a vehicle. Shop around and you will get one cheap.  I put an ad on one of those online parts finders   , one fool wanted £200  


http://www.pocuk.com/forums/viewtopic.php?t=96157

I would imagine that the g sensor is connected to the ABS ECU which is located on top of the offside rear wing (inside the car under the trim).  

See you  for more testing times

Well - I only had digital multimeter available, no use at all!

Asked at work, same story, digital throughout..

So..

Here is the all new, patent, Pajero Diagnostics Computer:



and here it is in use:  (note that I needed to use pin 1 in the top left of the port) (94 2.8 LWB)



It works perfectly!   Long pulses for the tens, short pulses for the units, just as described.

So anyway, Codes I got were 15, 21 and 32.

21 seems obvious, replace the front right wheel sensor.

however, the other two, G sensor output voltage etc, does that mean I'm looking at a new G sensor too?

Please could I have some guidance on a good source for both?  (I'm not far from fils Pajeros in totton, so may try there, but theyre not cheap..)

Thanks all

Hello basc

Well done on the new diagnostics kit I like it. Looks more reliable than microsoft.

The front wheel sensors are very difficult to remove in one piece, but if you are very patient it can be done.  The wheel sensors are also very expensive to buy new. If you can find one in a scrappers it is worth taking the time to remove them. I would try cleaning them first, may just be some dirt stuck on the end. Also check the wires and plugs.

Try fee bay for the g sensor there is always someone breaking a paj on there or put a wanted in the club classifieds

good luck on the quest

see you at the re-test

Hello mister emax and everyone on the coolest forum, same problem with me lighting ABS and so Japanese Drifting on snow , my mechanic says it is the G-sensor , and he remove it and told me to find a replacement , my question to emax , did you mean to connect the voltmeter one end to the diagnostic plug and the other to ground to read codes ?? if so the plug has many teeth , to which one ?? please explain a little if you dont mind about this voltmeter method , also for the removed sensor , it looks shiny , i took the top screws and inspect the board it looks well , when i tried to took the side screws of it , an oily fluid spilled a little and found out that it was filled with this fluid which surprised me really....so is there a way to fix it maybe or something in order not to be "screwed" by spare parts monsters ?? my truck is 93 sport pajero .
thanks a lot friends .

[Raed]

Oh sorry for that my last question looks dump because before i post i didnt look into the above pictures of the brand new Mitsubishi Motors Sophisticated computer diagnostic system , its clear to me now i should give it a try....but still want to read a comment from emax and others about my problem....my diagnostic plug is different from this, it has only 3 teeth, also the codes taken from this method do apply to other problems or just ABS issues? ...thanks again.

Hi everyone and greetings from the land of fire and ice
im new here because i have lots of fault codes showing when i connect the pin 1 to pin 4 on the abs light.
just wondered if anyone can point me to a list of abs fault codes for this car ??

also i have lots of knowledge of cars from being a mech for 20 years and have been recently getting into obd and obd 2 p.c sowfware.
can anybody recomend good software to use with mitsubishi ? ive searched for an mut iso but cant seem to find 1 ??
is there anything else that works well ?

thank you very much
