There is some reference to ABS in the BGB. Take a look through here: mr2.ie/mr2/bgb/mk2/

Re: ABS LIGHT ON DASH 1 Year, 2 Months ago Karma: 14
i had tryed that link yesterday,my prob is when i connect the E1 to TC on code fault test as they advice for ABS,its giving me power steering readings,im wondering if there is a diff way to check code faults on mr2 mk2 Rev3 models,as so far can only find check lists for older mr2 models online,im 2 days at it now,would be easier if i could find out how to check what excactly is the fault through code readings,before tearing car apart,oooohhh the fun off cars lol.
Thank you for trying to help,any other help would be very gratefull.

Thanks JOCK

In the frunk beside abs unit there are clips connecting the unit to harness, There are 2 or 3 connectors disconnect the connector with 2 wires going into the abs unit and try shorting E1 and T1 again.

Thank you,found that link myself this morn,no luck after trying it,will give it one more go in morn,then just start taking wheels off to check each brake,abs sensor.
Thank you for replying and your help.

Re: ABS LIGHT ON DASH 1 Year, 2 Months ago Karma: 14
ok for some reason cant check abs error codes on my car,tryed everything,fallowed every link possible,all system is letting me do,is check ECU and P-S Fault codes,so started checking abs,brake sensors on each wheel,first front wheel no,probs,1st back wheel bolt holding sensor on axle broke,2nd back wheel bolt came out but sensor stuck solid onto axle,cant get it off without risk off damaging it,last front wheel no problems,cleaned sensor then 10 bolt holding on sensor snapped going on,after it was only half way in,must say the 2 sensors i did get to see where in perfect clean condition,

So at end off another frustrating day,ABS light still on full time,and now have 2 sheared bolts stuck in my axles,
Arent cars such fun.

Just thought I'd mention that the abs and the power steering share the same fuse. So I am wondering if you maybe have a power steering fault.

Check the fluid level on the power steering and anything else to do with the power steering, can't do any harm to check.

I have read that the abs wiring corrodes over the years. I think they can be tested with a multimeter.

Disconnect the clip with 2 wires, the one you see me holding in bottom left of pic its around the abs unit.
then try the e1 and t1 while its unplugged

Re: ABS LIGHT ON DASH 1 Year, 2 Months ago Karma: 14
that doesnt work on my 1997 jap import model,they changed the set -up only works on older models,i can check ECU and power steering,but not able to check ABS have tryed disconnecting the abs service connector,but still makes no difference,i even went to the 2BRUTAL english forums and the guys there are having same problems with 1997 ,1998 models,anyway started taking off break,abs sensors on each wheel today,omg the rear ones where welded on wth rust.,had to drop off complete disc,brakes,callipers to take out sensors without damaging them,even then took myself and my father an hour to do just 1 rear sensor,by the way a heads up the 10 bolts holding on sensors snap with the slightest bit off pressure,and whatever metal they are,refused to be drilled through,to be taking out and re-thread,we eventually just made a new steel bracket,and TAP and DIE in new 10 bolts on axle to stop sensor ever falling out,so much for me thinking this would be a handy job,o well guess its why i love cars,always a challenge LOL
Thanks everyone for the response,i will post up when i find out excactly how to check ABS fault codes and how to clear them on the 1997 up model mk2s.

ALL ABS sensors removed cleaned,still no luck,took out abs computer module last night part number 89541-17050 ,going to get multimeter out today to see if all sensors in good condition,put a brand new battery in car saturday,and have checked all fuses,i will get to the bottom off this ABS light stuck on,even if it kills me lol,
Found info on my car from japan,was made on the 12,1997,last model to go off production line,before the Beams engine was brought out,its strange jap sites are teln me my g-limited 2.0lt NA has 197bhp,find this wierd as i thought only the beams na had that bhp,this is my model number E-SW20-AJMQF(L),anyway will update when i find the source off this fault,as for some reason,this model can only diagnose the ECU,Power steering,but not ABS with the paper-clip method.

you sure its defo that sensor? One trick is too use a multimeter to measure resistance on each sensor to eliminate the dud one.

Did that work,as yes very expensive for a original,178 euro i got quoted,if your primera one worked have you a link,and i will buy that instead

Its a pattern part designed specifically for the primera but I'd imagine theres little differences in them, they are mostly Bosch systems so I'd imagine they are interchangeable somehow.

I'll drag out the link but what reading was your working ones getting? I think the primera was around the 1400ohms range

I got the readings from a Nissan manual so make sure they are correct

anyway this is the lads site and here are the toyota parts he carrys no MR2:

stores.ebay.ie/motoneo-eu/ABS-Components...ta&_sacat=174018


Are you certain the sensors gone, if I were you I'd make / but a resistor around that value and stick a pin in each end of the plug you disconnected the culprit from - the light should go out

sensor deff gone,wont even give a reading when off the car,cant find any breaks,even stripped back rubber covers to check,dont want to pay 178 euro for a new one,so will see if i can get a loan off a good working toyota sensor,to try that,if not,thanks for you link and help,luckily no nct for 4 months yet so have time to experiment,as for now just took bulb out off dash as hate looking at it on,lol,will update if i get a standard,cheaper cost toyota sensor to work.

Re: ABS LIGHT ON DASH 1 Year, 2 Months ago Karma: 106
have you done a continuity check with the multmeter from the main plug

You just need about 3 metres of wire and crimp one end with a spade or similar and wedge it in the plug of the ABS unit that corresponds with the ABS sensor - after that run your leads between the extended cable and the plug the sensor slots into

Hope that makes sense B

Before spending any money grab a resistor (they are pennies) and plug it in and see how you go if the lights out the sensors 100% the culprit - I'd be confident its the sensor alright but you never know - if your in Dublin I can make one up for you sure I've a few spare here.

awsome,thanks for help,im just doing my dash,interior at moment,will put up pictures when its done,just put in a blitz panel filter,straight swap for standard filter in airbox,its a hybred filter that doesnt need that nasty oil to be sprayed on it,so going to test,finish these projects today,then will get back to the ABS sensor,weather to awfull here to be checking electrics at moment,but if i cant sort it out,might take you up on your offer off taking a spin to dublin.
Thank you very much for all your help and advice.

I'll throw it in an envelope and post it down to you - I reckon a 1000ohm will probably do the job but I'll see if I've the bits to solder up one at 985 in series.

Re: ABS LIGHT ON DASH 1 Year, 2 Months ago Karma: 14
So turns out my car is a Rev4,guy who sold it to me gave wrong info,o well great to learn something new everyday lol.
Put blitz panel air filter in,i no more expensive than standard at 37 euro from japan,but after 25killometers,just need to be taking out and blown off with a air gun,will save in the end replacing the paper air filters,it doesnt give any noticable bhp,and sound not a grunty as a cold air system,but still hoping it was a good update,braided brake hoses next,trying to get products that will last longer than the standard,original parts.

Re: ABS LIGHT ON DASH 1 Year, 2 Months ago Karma: 106
right mate - I had a quick look and I can only find 48K and 68k resistors

On a plus note you'll get away with using a 1k I looked at the BGB and it states readings between 0.9 - 1.5k


_KUNENA_BBCODE_HIDEIMG

Ok so €3.50 will get you 100 of these bad boys delivered (or you could get one from Maplin for the same price :P) - I'd order the below and I've used them before and the 1k resistor is used a lot in house alarms, etc so you'll find use for the rest at some point. I've used that seller as well before so all good there also.

http://www.ebay.ie/itm/Pack-of-100-1-4W-carbon-film-resistors-pick-value-from-100-to-10k-Ohms-FREEPOST-/231068912869?var=&hash=item35ccc7cce5:m:mSkcL4US1LiQ8M4yhAGD6XQ

Just be aware the light will go out but if you price the car it'll register again on the dash as the ABS knows the ohms should be fluctuating with the wheel speed

I'm confident the sensor is gone but this should clarify it 100%

P.s resistance is the same across all wheels so ignore the screengrab being front sensor
