Seems like the flow chart is pointing to the accumulator. This would be the canister that holds the pressurized brake fluid until it is needed by the brake system. They can leak internally allowing the pressure to bleed down in a short time, in turn, causing the pump to run too often.

I'm having the exact same symptoms with my '95 GS300. Is it possible to just disconnect the TRAC system and still operate the car safely? I have no idea how to replace the accumulator.

I hope this helps out for you guys with the frist gen gs300! it hard to get help around here!!!

first of all im sorry if i ansulted anyone! the tranny was rebuilt in 2007 no need for the whole rebouilt think! thanks anyways for the advise! and the tranny drove super smouth no grinds miss shist down shifeted when i told it too! i replaced mouunts all the seals motor rear main seal the works car is driving fine so i finished and i wanted too tell everyone the out come! thanks everyone for your help and support and HAVE A HAPPY THANKSGIVING!!!

so you had your tranny rebuilt in 2007 and somehow you still spun a bearing.....sounds like they did a shotty job on the rebuild or your REALLY beating this car 2 death even more than some people i know who race theirs . tranny on the gs300 fairly stout till like 450+ hp......

bro whats ur fuc-ing issue with me! ever time i post something you have something smart too say whats up!!! GET OFF THE D-CK FUC- BOY! IF YOU GOT SHI- TO SAY GET TOO IT!

the tranny spunn the bearing on the oil pump and forsted the oil seal out! so i found all the parts for under 20 bucks bearing,oil seal,pump seal,filter, so i put the tranny togther and its going up in the morrning luckly the converter was fine it looks like someone changed it already and the bearing didnt hurt it! it looks funky its all white no name date or anything i also think my motor was swapped due to yellow paint on the flywheel! my brother says its a jap spec motor cause of all the funky stickers (chinese) sh-t i dont understand! i hit everyone on the comeback later on! wish me luck

you might wanna check your gears while your in there and see if your missing a synchro or ne teeth off ne off them, y wouldn't you just replace the oil pump instead of sorta "rebuilding" it like you seem to be doing? if its a "jap spec motor" as you say it wont have Chinese writing on it......it might have Japanese writing on it but highly unlikely for it to be Chinese writing. that's kinda insulting too, don't you think.......especially to ne Asian people on here

OK. Maybe only 2 of the items are related.

Does your cigarette lighter work? That same fuse powers the AC panel. You may have a coin or something in the lighter socket causing your fuses to blow.

As far as the brake lights and shifting, maybe the brake light switch is not working properly. I may be mistaken, but I thought the same switch controlled both the brake lights and the solenoid release for shifting out of park.

Tom

WELL I FIXED IT!!

to everyone going through it heres how!

it turned out to be the fuses the seemed fine when i checked them with a test light right ! but the had a film of muck on the and the really didnt make good contact with each other i got some new fuses and scrached them to make a good conection! make them go in kinda rough fit! for good connection!

i checked them with the test light and it fooled me so be aware take them out replace its a cheap and easy fixs and some where to start if your going through the same trouble i was ! thanks everyone and i hope it helps some one out!

Be aware - this is just a guess. I have not messed with the wiring to the antenna yet, just replaced the mast. But as there seems to be a control box with a multitude of wires that are cnnected to it and the antenna, my guess would be that the three wires are +, - and signal. The + & - being the hot and cold of your 12VDC and the signal being the wire from the radio that tells it when to go up (or down).

What are the colors on the wire insulation?

bro i have no idea i looked around and found out for the relay is (yellow and red) (white and blue) and( pink and green ) !?!?!?! i checked them ran power and ground to all of the and no luck! it cant be that hard ! i checked if it still worked by runnin its own + & - too the motor and its still works great! i need to send it a signal when i turn on the tunner it it goes up and when i turn it off or cd on it goes down! how many people have after marget radios and there antenna still works?

OK ...Obviously some folks change the stock head unit with something a little more "powerful"....which I managed ..... My problem is integrating the new head units single power antenna lead to run the 3 wire stock power antenna. Can anyone shed some light on this for me?

Thx Clyde

hay same here going through the same problem i dont know how to wire up my antenna to work for my new radio!!?!??!??!??!

can anyone help me out PLEASE AND THANK YOU!!!!!!!!!!!!!

well this dam sc is being a pain in the a--! my a.c cluster stoped working and i looked and i looked i found the troubled area! the driver side kick panel with the fuse boxs is acting up so im askin if anyone heres gone through it befor and what they did to fixs it?

plus my brake lights stoped workin too! i checked fuse blubs grounds what else can it be the car doesnt wanna shift out of park ether!

I may be wrong here (and someone correct me if I am) but I don't think the 92 or 93 models had "fog lights".

There were cornering lights that only lit up when you activated the turn signal.

At least that's how mine work.

you know my friend i think your right!!!!

i wired mines to turn on whe i turn on my lights! looks good i think so!!! but thanks again.

MINES DONT WORK I DONT KNOW HOW TO USE THEM CAN ANY ONE HELP?

WHAT ABOUT THE RPM GAUGE MINES IS OUT WHAT SHOULD I LOOK FOR??

THANKS VERY ONE AND SORRY FOR THE CAP LETTER I FORGET SOME TIMES

Took the car to the dealership & long story short, I need a new ECU. They said 8966124312 is the # for the replacement but I would like to know if 89661-24332 (the number of the one on ebay) is compatable. It is also for a 92 sc300 but not sure if that 2nd to last number matters... someone please help so I dont have to shell out a grand for a new ecu.

thanks,

Steve

SORRY TO HEAR THAT BRO!!!

i just whent on the same bad trip! ! ! got it sucks try ebay and craigslist in miami fl i think some one has one for you ill look for you and send you a link! heres the # to the guys that fixed mines 305-387-7759 solo cumputers he does great work call him up for price on repair!!!

code 27 is a bad o2 sensor. check along your exhaust system for week ones.

i have it saved to my favs!!! long time agoi hope all this info helps everyone else! i really can try anything else till i get a new ecu! i really wish i never got into this car!!!!!!!!! ive spent about 700 bucks on making it look good run good a.c tune up i mean so much cash right after i got it!!!! i havent even put 100miles on it! it drove home frome the guys house that was it! i said let me give it a tune up you know to welcome it too the new home and look how it wants to act! i lalso have a 3rd gen es300 pushing 250k on it and no trouble what so ever in the second owner i got it with 60k almost new i beat the brakes of it a real trooper 140mph on the highway at 3:30 am thats what i call a good lexus its my wifes daily drive it gets miles all in all i realy wish i never got this car as some as its up and running its sold for what ever i can get for it!

well i fixed it! its was the ecu that was burned!!!

then the idel air control valves gasket was bad fixed that too!

now i have code 13 - RPM signal no. 2 and the car sputters when i drive off and cel is on too! can anyone give any ideas on what to look for??? is rpm signal #2 the coil and if so witch one drives side next to the a.c compresor or not?

That would be the passenger side. If you remember when you changed that rotor; you had a 2 wire harness coming out the front of the lower rotor cover. That is it. Look for it's connector just above the thermestat housing. Check for broken wire(s).

!!!!!!!!!!!!!!!!!!!THANKS A MILLION YOU ARE THE BEST!!!!!!!!!!!!!!!!

I WHEN HUNTING AND BINGO THE WIRES ROTTED AND THE GROUND WIRE RAPPED AROUND IT WAS MAKIN A SHORT SO I FIXED IT THANK TO YOU! ! !

I wish you the best bro you made a friend here in MIAMI FL if your ever down here hit me up ill show you around and if you want i got some chickenhead around for you! thanks a million ROB
