1Gen-SequoiaGeneral discussion forum for the first generation 2001 to 2007 Toyota Sequoia.
This is a discussion thread titled "VSC Trac, VSC Off, Brake, ABS lights... all on, all at once.", within the 1Gen-Sequoia forum, part of the SUV Forums category.
VSC Trac, VSC Off, Brake, ABS lights... all on, all at once.
So I'm driving along, and notice both VSC lights, the emergency brake light, and the ABS light all are on. Next time I restart the car, all's normal for a few minutes, then they come on again. Same thing this morning... drive along normally for a few minutes, then the lights all come on.
I just spoke to Toy Financial Services about possible warranty coverage (certified) and the guy on the phone thinks it's the ECU, and not covered.
What do you guys think it is? If it's something that's not covered, I'd rather fix it myself, if possible.
Re: VSC Trac, VSC Off, Brake, ABS lights... all on, all at once.
A 2002, eh? If I had to guess, I'd guess the brake booster before the ECU (simply because the brake booster is a known weak spot on the first few years of the Sequoia, while a failed ECU is pretty rare).
Do you have the capability to read the codes? Takes some of the guesswork out of the process (although, if it's a brake booster, I think you have to do some funky jumpering to pull the code). Check out some of the related threads to this one -- some good info there.
Re: VSC Trac, VSC Off, Brake, ABS lights... all on, all at once.
try checking your brake fluid level. The sensor is very touchy. Mine was reading full but the dealer filled it up above the level & I have never had a problem since.

I've had 3 things happen to my Sequoia that made all the lights come on. Low brake fluid was just one of them. I think bad oxygen sensors too? I can make mine come on temporarily by just slamming on my brakes on a gravel road. Come back on when the power is cycled. It's a weak point in the diagnostics system to be sure.
I think lights come on if you haven't tightened your gas cap enough also...

I too have had some very intermittent VSC issues on my 02 2wd and the codes that the dealer read were pertaining to the Sensor in the booster and another code for the VSC/Trac Computer. I watched him with the scantool and the brake sensor was acting fine at the time.
I have the money to take it to the dealer but I am a frugal person with a lot of mechanical ability. If you were me would you replace the booster? Or would you take it to the dealer?

If I knew it was the booster, that's half the battle. Yes I'd do that myself.
Detailed shop manuals available in PDF format - if you search on TS you'll see mention of it.
Re: VSC Trac, VSC Off, Brake, ABS lights... all on, all at once.
I think that you may all be interested in this post from another site.... I had the same problem with my 2003... had them replace this sensor and never had another problem... I have been posting this on several sites now since I finally found something that works...
Tell the Dealer to pull their head.
If you jump the DCL connector under the dash--> PINS (TC & CG)
The ABS light will flash a deep rooted code, My guess (i have a crystal ball) is it is a 63.
This indicates and malfunctioning pressure sensor in the Brake Booster assy.
If they find NO CODE, my other sugestion would be the SKID CONTROL ECU.
It is bolted to the ABS Actuator under the hood. There is a TSB on 03 SEQ's for a problem with them, every now and then a 01 has the same problem.(but unlikely)
My best guess would be the BRAKE BOOSTER 90% sure of this.
Re: VSC Trac, VSC Off, Brake, ABS lights... all on, all at once.
I will say however - when the traction and skid control did not work for me in this time period, it always brought a grin to my face to prove to people that you can do donuts in a full size SUV on loose terrain . I would seriously advise against trying this though hah.

Re: VSC Trac, VSC Off, Brake, ABS lights... all on, all at once.
Hi guys,
Looking for help here. I just had codes pulled for the VSC issues in my wifes truck (2003 SR5 with 70K miles) and everything points to a Skid Control Computer. I was quoted $1600 for part and labor.
Here are the codes...
B0101 - Open in D SQUIB Circuit.
C1203 - Engine Control Comm. Circuit Malfunction.
C1231 - Malfunction in Steering Angle Sensor.
Please let me know if any of you have any suggestions.
Thank you
Dmitry

Bump...
I can't believe no one has any suggestions. Do you all agree with my assesmnent that it need a new ECU?
