Solara ECU Problem - How to reset?? - Toyota Nation Forum : Toyota Car and Truck Forums

BamBamT · 01-25-2002, 01:17 AM

I have a 99 Solara V6 and am having problems because my traction control is always engaged. When I floor the car, the RPM's go up, but theres no power to the wheels. Anyways, I was told by many people to reset the ECU. I did by disconnecting the battery (both pos. and neg.) all night, to no avail. I heard that to properly reset the ECU you have to do it right on the ECU itself which is under the centre console.

Anyone know how to reset the ECU?? Can I manually reset if I get to it, or is a computer required (from dealer)???

Unplugging the positive terminal of the battery for 15 minutes should make the ECU a clean slate.

But for your problem I don't think resetting the ECU will do anything. On our 2000 XLE V6 its the same thing. Traction Control is on my default. There's a switch to turn it off, but everytime you restart the car it is on again.

I think you have to go and mess with the circuits and relays to disable traction control. You might even be able to wire it so that it is only on when you push the button, but I dunno about that.

I thought Solara have the "Trac OFF" button? :???:

When the traction control is turned ON you will see the light show up on the dash, at least that's how it works on my 96 Gen3.

Yes, works the same way with his Solara and our 2000 Camry as well.

Man, I think my next mod is to have a TRAC OFF button (I don't have it on my 96).

Henry are you reading this?? :grin: :grin: :grin:

Edit:
I've talked to the guys at DPE when I was doing my dyno (my first 2 run had the TC turned ON), they said I can take it to Yoshio and have the TC permenantly disabled, but that sounds silly because what's the point of killing it when it's actually a safety feature right?

Of course I am! I really should be working though....

I'll look through my wiring diagrams, get some sissors and a switch, and voila! There's your on/off switch! Now it's just a matter finding a nice place to mount that switch....

I don't know if it's as easy as snipping a wire or two but I'll look into it.

A girl at school had that same problem we just took the pos off the battery and let it "reboot" ... problem solved

Does the Solara have the VVT-I? I know it has the updated 1MZ-FE motor with the 200 horses under the hood, is that any diffrent than what is in my 1995 ES300?

Rookie Solara · 01-30-2002, 09:20 PM

No....Solara is no VVT-I...only on Celica and the new L4 engine 02 Camry...the V 02 Camry still running the same engine only have the different intake.

WOW, what kind of digital camera is that? That is an awesome picture! Please post more pics of the rest of the engine, I would love to see the whole thing.

Thanks

where can i buy that bar that goes across the engine? I want one for my ES300, can it be installed in mine, I heard that it adds structural regidity.

speedemn · 01-30-2002, 11:22 PM

It is called a front strut tower brace (that's the right way to put it) and you can get it on ebay. The layman term for it is strut brace or something along those lines.

There are different brands all of which have the same effect. So just pick one based on looks, to what suits you.
