Thanks for the quick reply.... between the time I posted and now I have already fixed it lol, Found a link on how to take the instrument cluster out took it to peices and found several corroded connections, cleaned them up with a nail file and put it back together and now its fixed :S pretty random but im happy it was a cheap fix.... and only used a pen knife! lol Thanks again! Gaz

Hi Again.... Using my Dads car for a few days while im getting settled in Uni down in Oxford went to a lecture in it came back had lunch went to go to another lecture and tried to start the car dash lights came on then all went dead. Openend the bonnet and fiddle with the battery cable which was loose so tightened it and had juice again, had to wait the 6mins for the immobiliser then started the car and off I went only to notice that non of the dials where illuminated and werent moving. The car had a problem when it was bought 3 years ago where the dash wasnt working but this was fixed by an electrician for £40 and was some solder or wiring on the circuit board that had shorted.... something along thoes lines anyway. First thing first, Is there any fuses specifically for the dash lights and dials? My problem is that im 220miles from home with non of my tools and have no idea where to begin with removing this dash, Ive had alot of experiance with more basic cars and am trained mechanic but where do you start with such a complex looking dash, every clip/screw is hidden and my lack of tools is gonna hinder me some what. Any one with any information? Any Ideas? or Local that could assist with the fix, or know a good place local to take it!? I cant afford to take this to a garage and have them charge me £200 labour for a job I could normally do with the right tools :( Thanks Guys! Gaz

Thanks for your reply... the detials had to be from Lexus themselves which I obtained by e-mailing lexus and suprisingly they gave me the exact information of the originally equipped battery which was nice of them. Thanks Again Gaz p.s. please see my new thread as I have another problem!

Anyone got any info or know where it would be? Its not in the owners manual.

Hi guys, Im doing a project for uni about batterys and need to know the manufactures recommended specs on a GS300 Sport 1999 battery... Info needed includes the CCA/ CC (which is the cold cranking amps), Ah (amp hours) and the overall dimensions. Any copies of official lexus documents which have this info on would be awsome, I was hoping I could find this information in my owners manual and was going to scan it but I cant seem to find it. Cheers Guys Gaz P.S. Need this by friday :(

Im abit confused why I should touch the other sensor when the error code is for the one that I have removed. This sensor was removed so I could take the up-right off to change the wheel bearing. It was removed once and refitted fine without touching the wheel bearing then removed a second time, wheel bearing fitted then after putting back together the ABS, VSC off and VSC lights were all on. Error 31 on ABS and 43 on VSC... will remove these codes as suggested and see if I still have issues, which I think I will. Will be scoping the sensor tomorrow anyway to see if its still working. Gaz

Thats with the ignition on I do the brake peddal thing yea? I shall try this when it stops raining and then see if the error comes back. Will let you know how i get on later, Cheers.

Again thats gonna come in very handy, thank you. I did the diagnostics as you suggested and am still getting 31 from the ABS light - front right ABS sensor Malfunction 43 from the VSC light - ? dont know what that is ? After reading the ABS fault finding PDF you sent it might be that the sensor is not fully in all the way as i struggled to get it in due to the seal that didnt seem to squash in easily. However if this were the case i would have though that the error would not be found untill the vehicle was moving but the light came on instantly. Worst case the sensor is knackered so, where does it connect to the loom and how much would a new one set me back :( Gaz

cheers for that, they should come in very handy. I have used a Bosch KTS diagnostic system on it but this could not read the ABS control unit for some rerason but did manage to read and remove a past fault in the engine managment. However when it was connected via the OBDII the ABS light started flashing and gave a code 31 which i found out from a previous thread is Front Right ABS sensor malfunction... the one I removed :S I cant believe I damaged it though as was extreamly careful but it was left overnight not connected to the hub. I am going to a place to try some more diagnostic equipment on it and to scope the sensor to see if it is working or to find out why it isnt. Thoes wiring digrams will deffinatly help with that too. :) Cheers again guys

cheers guys. I did disconnect the battery but that didnt work and the lights for ABS and stability/traction control are still on after several ingnition tests so im guessing somethings gone wrong some where. I cant believe i damaged the sensor when removing it as i was very careful. cant find a fuse blown or anything either? can someone confirm which fuses I should check and what else could cause my problem. thanks again guys Gaz

take the what out the battery? lol you mean just disconnect the battery yea, does it matter how long for? cheers

Hi guys I have an ABS fault code after removing my front off side ABS sensor, its been refitted properly but now I need to know how to clear the fault code to see if its gonna come back or if it was a one off due to the removal of the sensor, Any help greatly appreciated. Cheers, Gaz

Hi... im gonna be taking my dads GS300 of him soon its a sport model and is on a V plate. It needs abit of work on it and I am hoping you guys could give me some info and advice about this car. Basic question, what "Mk" GS300 is it being on a V plate... Im guessing its the Mk2? Need parts such as cam belt kit, plugs and possible an exhaust so was wondering if you guys know of any specialist shops/ websites where I can get these parts cheaper than dealers etc. I also need some random parts such as a replacment stero cos the screens gone on mine, need undertray and inner wings as there hanging off. Could also do with the washer bottle and motor for the light sprayers. Im sure im giving the impression this cars abit of a dog but I just want to get it back to its former glory and tidy up and im sure you guys can appreciate that :) Cheers for any help Gaz

As per title, but am also looking out for any other GS300 parts like bonnet, wheels and a replacement sport front bumper. cheers Gaz

Thanks for that... will come in hand, pitty I dont have the KTS available to me now to check the actual values. Wonder if it can be done by monitoring the volts. I still cant see why it wouldnt give a fault code if its the TPS or Throttle motor... if the motors not keeping up with the pedal position sensor the TPS would pick that up and should give me a code. Will clean it all out tmoz and watch whats happening with the opening and closing of the throttle butterfly. Gaz

ahh right yea, the aircon thing makes sense. Ok I will try cleaning the throttle body as soon as I get chance. To adjust the throttle position sensor should I just look at the Volts that its giving at fully open and adjust it until it actually gives its maximum voltage, would this be 4.5volts? what should it be at when closed? 0.6v. Or is this not a very effective way of adjusting, I no longer have the bosch KTS available to me as well btw. Cheers again, hopefully were getting somewhere. Gaz

Did think dirty injector so will try abit of injector cleaner and some V-Power, dont think this is going to solve the problem but might as well give it a try. Colin : I have notice, since you said about it, that after driving then coming to a stop like at a junction the car sometimes stalls but everytime it has done this the aircon has been off! It has not stalled when coming to a stop with the aircon on!... not to sure what that would mean to you but you did ask about the aircon? I will be getting the gearbox flushed professionally and will make sure the right fluid is used, weather this is the fault or not I still think it needs doing. You saying about the throttle motor has also made me think because when I was using the Bosch KTS to read the ECU I noticed that with the ingnition on reading the actual values, when I put my foot flat on the throttle so it could go no further it was only saying it was 79% open??? could this indicate a throttle position sensor fault? faulty throttle motor? I suppose this would cause hesitation due to the motor not reacting as quickly, but like I said no fault codes? and why would either of the above cause it to stall... maybe the motor not being able to open the throttle enough for idling? I'm puzzled ... so many possible things and no definate indication on whats at fault, a long and potentially expensive process of elimination. cheers again guys, Gaz

yea idle is fine... drives fine most of the time but the hesitation from stand still can be abit sevre at times, must add that the gear oil does look abit brownish. I was going to change it my self but not much point as you can only replace 2.4litres and the box holds 8ish litres so will most probably have it proffesionally flushed. I have read the ECU and all is good no error codes on any of the systems and all the actual values from the sensors seem good. Was wondering is the throttle butterfly operated by cable or does the cable just provide information for a throttle butterfly motor? cheers, Gaz

Hi all, My dad has recently bought a GS300 Sport that seems to have abit of hesitation when pulling away. I also noticed that under very light throttle with abit of load the car stutters and revs go up and down as if it doesnt know weather to go or not. It has also stalled on me once when stopping at a junction. Hoping someone on here may be able to help as it seems to be one of thoes problems that comes and goes and could be caused by a number of things :( I have checked fault codes on the ECU and none were found Pulled a plug and they are quite clean NGKs Done oil change Done air filter change ...thinking maybe MAF sensor? Fuel pump/fuel filter? coils...are they coil packs on these? maybe needs a gearbox flush too? cheers, Gaz

Cheers for the links, I will get there eventually...the box I have isnt like that, the one i have fits in with the rest of the dash and panels well as it has the same style lights and graphics and actually says celsior in the TM name style on it, It has two knobs one to sort the front and one for the rear. I usually have it lower as it stops it feeling like a boat and isnt really any harsher than the normal ride hight, maybe a little bouncier though. If you find any more info on the screen filter let me know, cheers Gaz

Cheers for your replys. re-the amp, dont think its speaker related as they have all gone down? head unit comes on and it searches and everything but no sound at all? damp boot caused it i think as the car stood for a year because of suspension issues. re- the steering, dont think mines leaking too bad just some slight seepage. I am a mechanic in training and my dad used to be a mechanic so I dont go to garages :) you mentioned the ball joints and I had forgot that I think mine are knackered and this could be the problem its just strange how its intermittent and doesnt effect the whole of the turning just certain spots when turning the wheel. to be fair this car isnt very well, air suspension is still going down over night due to a leaking air bag, the display monitors have gone black, the ball joints are on the way out, theres a knocking from the rear and the steerings on the *****. The other issues arnt as major as the steering though...well the ball joints are. I need to look into this filter thing though... also any of you celsior guys got a special little box that can lower the front and rear suspension seperatly and can lower it to the max? mine has one looks like an add on but it is a genuine toyota celsior control box? also in some of the documentation that came with the car it was once owned by a toyota race team so it seems? thanks, Gaz

Hi, cool 3 celsiors...you got air suspension? any idea where the amplifier is in these things mines gone pop. pm me Anyway thanks for the reply re-the steering, I dont think this is an air lock and pretty sure the system was bled. Is there a filter somewhere on the powersteering system? I thought I read that there is. has anyone else had any problems with the steering? thanks again, Gaz

Hi Guys, My first post on here hoping some of you can help me out. I have a 1992 LS400 import (celsior) that has developed an intermittant steering problem. The sysmptons of the problem are that the steering goes stiff then slack then stiff then slack when turning large corners i.e. when you have to turn the wheel through a great angle/degree. I did suspect the UJ might be the problem but this seems ok and as the problem is intermittant I'm guessing it could be a problem in the power steering system, Is there any known faults on this model/year vehicle? It did lose alot of fluid and it has been fully topped up since and the level monitored all the time and I would say it has gone down a very slight amount, I did read on here that there might be a filter to clean or somthing as it does seem like lack of pressure or something? Any help and advise would be greatly apreciated, Thanks. Gaz
