I would advise against "engin_ear"'s suggestion on floor the car right after reset. (not on a 15K engine dude

LOL what!! your post was ok till i saw that statement, when do you suppose it's okay to rev an engine? After your third timing belt change! After the break in period, it should be ok to rev occasionally....

also, here is how I reset my ecu, remove the fuse 30sec, I think the supra ppl do this also, same fuse, 30 sec, EFI fuse (25A)
I just checked my fuse box and im missing that fuse?


My fuses are lined up

[15] [15] [15] [10] [30] [X] [5] [25]


I bought my 2006 sc430 second hand. Whats the deal with the missing white fuse? Has my fuse box been modified in such a way to turn off the computer?

Missing fuse question is answered here

However, I pulled the ECU fuse (my car still started without it, I suppose that is not abnormal)

Unfortunately it did nothing for my ABS and VSC lights which still remain on, and now I can't adjust my steering wheel, the up and down tilt does not work sheesh

As i told you in the other thread UNTIL you actually fix the speed sensor that got ripped nothing short of pulling the bulbs will clear those lights....

mechanic inspected and they don't appear to be ripped. I suppose what you're saying is to whip out the ohm and volt meter etc?

Secondly, failure in these sensors would cause both VSC AND ABS to fail?

OMG man...i even told you in another thread that ALTHOUGH they physically might appear to be ok when you take a meter and ohm them out i almost guarantee they will be bad. im done, moving on now....

Like previously stated yes you need to actually check the sensors readings to see if they are in spec or possibly just open. A visual inspection is all good, but it doesn't test the sensors, they do go bad or read out of spec sometimes..

The VSC light likes to come on along with dozens of other codes and problems. It doesn't mean it's necessarily an issue with the VSC. The ABS/TRC/VSC are all functions of the ECU inside the cabin by your brake pedal. So some codes throw both VSC and ABS indicating it's a function originating from that module. As well as the VSC is triggered/controlled by readings from the abs rings, so yes a bad sensor can affect both systems.

Sometimes if your sure everything is correct and the hardware is fixed, you may still need to reset the ABS/TRC/VSC module. You do this by inserting a jumper wire or paperclip in the TC and E1 pins on the diagnostic port under the hood. Then turn the key to acc and press the brake pedal 8 times within 5 seconds and then turning the key off.

Thanks much - now on to revisit the speed sensor and price it out without having to spend over $200

I suppose if the sensor cannot determine the speed of the wheel, then the computer doesn't know when to apply the brakes, thus inhibiting ABS, and for that matter, VSC - so suffice to say that a bad speed sensor causes both to fail, whereas something else could cause only one to fail at a time.

Better fuel economy a result of resetting the ecu also? Cars been getting progressively worse fuel economy since I got it and I hardly ever get on it.

I use to do this for my G35 but the only thing it improved was the auto tranny's shifting

When you reset the ECU, you are brainwashing it and forcing it to relearn the parameters again. After the relearning process is completed it will run back to the normal state again. Not much benefit from resetting the ECU.

^agreed. Was a pleasurable experience for the first, I'll say, 200 miles. Then back to normal.

Default what else does resetting the ecu do?

Ok the reason for me asking this is because i have lost the only key that i have for my 2002 GS300. I am a starving student that has no money , zero, zilch, nada cent in my pocket at this time. i can't even get to work without a car and rent is due. I feel like my whole world is about to erupt. I plan on pawning whatever it takes to get the money to get a key cut or ignition replaced with a used one with a key.($90.00+/-) But I would still need to "flash" the ECU to allow the new key/ignition to reprogram or "teach" the ECU which will now be in "learn mode" . Thus matching the two together. SO MY QUESTION IS IF I RESET THE ECU IS THAT GOING TO DO THE SAME AS FLASHING IT. BOTH PUT IT INTO LEARN MODE. BUT WILL IT ALLOW ME TO TEACH IT WITH THE NEW IGNITION AND KEY? PLEASE SAY YES!!!! Thank you for your time and thoughts on this matter.
