Hi Guys,
Ive been having some troubles with my ABS warning message at the bottom of the dash(where the time usually is). Recently, the ABS bong started, accompanied with the TRC OFF light and the (!) symbol, as well as the japanese writing stating brake system error. After searching, I discovered how to do the diagnostic test for the abs/trc systems, however the problem I have encountered is that the actual ABS warning light never appears - even when the car runs through its tests on startup. I cannot ever remember seeing the ABS light ever since buying the car approx 16 months ago. So I can't do the ABS diagnostics, as there is no abs light to actually flash.
The TRC diagnostic gives error code 43*1 (TRC OFF light is on). I am thinking this may be the nitrogen accumulator from what I have read, but want to be sure before forking out the $4-500 for a new accumulator. The accumulator pump runs for about 10 seconds on startup, then every second press of the brake pedal for about 2 seconds.
Is there a way to tell why the ABS light is absent? Is it likely to just be a blown bulb, or something else? Is there another way to do the ABS diagnostics?

Had this problem with my old soarer.
I got it fixed by sports and luxury in Melbourne. I think the relevant parts that got replaced was an ABS switch and the TRAC computer. I'll have to look at my bill to make sure. Hope this helps.

I knew mine was kaput when it would run every 10-20 seconds whilst just cruising; I could hear this squeak like a little bird. I'd be inclined to leave it for a while but be mindful that a $4-500 cost will more than likely be coming up - put $20/week away.

So I fitted a reconditioned nitrogen accumulator (thanks Steve) and my problems have not gone away. I have re-set the error codes but sure enough when restarting the engine the dreaded 'bong' and ABS error message is back. Any further ideas on how i can solve this annoying problem and get my TRC and ABS back?

Might need to get the wheel speed sensors checked out but I think they bring up a different code. As Dean mentioned earlier it could be the pressure swith or ABS computer or even a bad earth. You really need a good friendly expert (local ideally) who won't rip you off.

i have got a similar problem. often when i 1st start the car [cold] bing up comes abs , drive for 15 min turn off start again ....gone.? if i give it a 'flogging' then the abs warning sometimes comes up. the jumper pin diagnostics leads me to abs computer.....changed that ...no different. i reckon i have got a bad earth or a poor connection in the system....anyone got any suggestion please .

I would have thought if the ABS sees an open circuit (light blown) it would give warning messages as it can not light up to warn the ABS is working or not?

I still haven't sorted this out. I have replaced the accumulator and bled the brakes, but it is still occurring. The ABS light does not work/does not come on when the ignition is turned on, and does not come up when I do the abs diagnostics.
Can anyone verify would Dave has just said about the possibility of the abs light being blown and causing this?

stick your head in the foot well and look up to where the pedal pushes the shaft into the master cylinder if its leaking brake fluid. ( which alot are starting to do) then you will be up for another master cylinder unit (no way to fix it yet)...

Thanks Dave and James - your advice is much appreciated.
Its not leaking any fluid. Lexus of Brisbane And Toyota dont want to know about it as its an import. I'll try and get in touch with Tuff Toys again to see if they can have a look and help me out.

AArrgghhh! This is still driving me crazy. It has been looked at by Tuff Toys again, who extracted code 51 this time. They seem to think that the reconditioned accumulator I had installed is not working. The Pump runs every 10 seconds, even when the brake pedal is not touched. it also runs every time the brake pedal is depressed. It runs for less than 1 second each time. It is still displaying the ABS error as well as the (!) symbol and TRC OFF. I have read through heaps of other similar issues, but everyone seems to have a different idea as to the cause - the trac computer, the abs computer, the main ecu, the DVS switch, the accumulator, air - the list is huge.
I am looking to sell the car soon, and I know that it will be impossible to get a good price for it with this problem - which is a shame as its a 95 model in otherwise really good condition. Is there anyone else in Brisbane that would be capable of fixing this?

Finally fixed!
the accumulator turned out to have failed, which Peter Taplin replaced. Once I fitted the new unit (and bled the entrie system and replaced with new DOT3 fluid to ensure this wasn't the problem, the error was still there, although the car braked much better than with the failed accumulator.
I then ordered a new DVS switch/sensor thingy from castle hill toyota ($115 delivered). My husband installed it - 30 mins, 4 skinned knuckles and a burnt finger and the errors were gone!

Hi Narvey
the part number is 84220-24010 - call James sloane at CAstle Hill toyota and he will get it for you - when I called he only had 2 in stock on the computer system - so there should still be one left.
I have fixed the intermittant ABS / TRC error on my 4.0GT.
The car would be fine for a while then the ABS / TRC would trip, indicating TRC 43 and ABS 51 errors through the diagnostics port.
the problem was the Differential Valve Switch (DVS) or Pressor sensor, which can go out of calibration and cause a nuisance trip of the ABS / TRC circuit.
This part (Toyota part# SWITCH ASSY: 84220-24010) is located below and behind the brake fluid reservoir and the engine compartment (see photo). It was previously out of production, but some more have been manufactured by Toyota in Japan, so now should be available again worldwide at a unit cost of sub £40.
It is a dog to get to, there was just enough room to get a spanner to it from the side, though watch that the female connector doesn't disapear under the Reservoir, and some brake fluid will leak out of the hole if you don't replace it immediately!
I am unsure if the same error codes will appear on all cars with this type of intermittent error, but this problem is NOT LISTED in the repair or workshop manuals either for the LS400 or Soarer. Please don't hold me accountable if this part does not fix your problem, but I figure that at £40, it is a reasonable place to start if you have this type of error on your car.
