It could be. My traction stopped working a while ago due to the fact that the traction ecu went bad and some other stuff so it was throwing codes. The dealership reset some stuff and fixed the abs and said i needed a new trac ecu.
More than likely you've popped a fuse(i think there are two) or one of your sensors are bad. I would check your fuses in the engine bay.
To answer your question, abs does still work with trac disabled. Lots of guys have gotten rid of there trac and still love good o abs.
Along the same lines, I noticed my ABS light was lit up today too, along with the Trac light. I now know that I don't even have the traction control pump and valves installed in my Supra anymore, but it looks like I might have a problem then with my ABS?
Also, does the master warning light in the tach come on when the ABS or Traction control is off or sensing a malfunction?
:lol: I have bled it motor off, motor on, and tried everything I can think of - it is ALWAYS spongy. Any other Supra I get in has a firm pedal - not mine. I'm 100% sure it started when I pulled my TRAC Pump I know some cars have to have special things done to open up the various parts of their ABS pump to bleed properly (Corvette for instance) but I don't know that this holds true for the Supra. Looking at the factory manual it says to jumper some wires - which then use the TRAC Pump to bleed the system - argh!
I know how to bleed brakes and have bled these various different ways - about 3 times now. My next step will be one of those vac bleeders but I'm pretty sure there's air in the ABS pump thaqt's trapped. As for replacing calipers or the master - nope. This began the DAY I pulled my TRAC Pump. Worked fine prior to pulling it, soft pedal afterwards - I installed a Line Lock too. Pumped the fluid clear starting at the passenger back, driver's back, passenger front, driver's front. There's got to be a way to get the danged passages open in the ABS but damned if I know how. On the Corvette or maybe F-body you have to drive over a certain speed, stop without using the pedal, and then bleed them without turning off the ignition or using the pedal :dunno: Not sure if our car is funky like that - maybe jumpering the thing for the Trac Pump will do what I need despite it's not being there?
i did the diagnostic test...
first it was the egr system (code 71)
now when im trying to read the next code to fix the next problem
all the engine check light does is flash repeatly
what does this mean guys?!?!?!
can't figure out the problem at all.. thanks!
hey guys so i'm posting this here because i feel like the most knowledgeable people will see it. here's a quick run down of the story so i've had my supra for a long time now. first tried running 7m's which was a nightmare did a built one only to have the head lift from the soft 7m head problem...
I've been tinkering with the idea of running a DBW throttlebody on my stock intake manifold. Bosch makes a range of universal dbw throttle bodies, and a company called TAARKS (from down under) makes an adapter plate for the Bosch 68mm to the factory VVTi intake manifold:
.....it looks like...
So I've been keeping watch over the past two years (as many others have..and for longer) for hybrid turbos which retain the sequential operating system and offer significant hp gains.
Well Stu Hagen, King of the Sequential twins (not necessarily "stock" sequential twins in this case), has come...
I just bought a NRG short hub for my Supra. When I went to remove the stock hub... I noticed there are four wires that's soldered onto a piece of circuit board. To remove the stock hub, I would need to cut those 4 wires off...
Does anyone know what are those 4 wires for??
