I took my 2003 T4R to the dealer today for an oil change and tire rotation. As soon as I start to drive away, VSC TRAC and VSC OFF lights appear... needed to pick up my son from school and couldn't go back in to complain. Got home and researched, found this thread and figured I'd give it a shot before heading back to the dealer tomorrow. I had no wire so I used (2) large metal paperclips. Followed page 7 of the service bulletin and it worked like a charm. Lights are off, drove the vehicle around the block and the lights have stayed off. Thank you for the quick and easy fix and saving me the hassle of explaining this problem to service writers who prefer the most expensive fix of replacing parts!

I just used the info to clear the lights on my 03. It worked on the first try and saved me a trip to the dealership. I had some scrap wire left over from a trailer wire kit. I just stripped and twisted the ends, put the 2 wires in the correct pins, and followed the TSB. It took less than 5 min from start to finish.

If anyone's interested, here is a thread of how to disable traction control and vsc without any actual modifications, as well as a video demonstrating the tsb that was mentioned in this thread. Enjoy!

Disabling TCS and Stability Control

Thanks to the OP and person who posted SB. Glad to get these lights off the dash.

Thanks so much MicaBlue03. Eight years after your original post, I encountered this exact problem after taking my '04 4Runner for a smog check. I appreciate the level of detail. It helped me understand the nature of the problem as well as how to fix it. Much appreciated!!!

Micablue03 - thanks for the detailed description and steps. It worked like a charm. And unlike some others who had to do it multiple times, for me it worked after one try.

Thanks for providing the TSB bulletins on this thread. I disconnected the battery today, in order to reset the back hatch powered latch, which had stopped functioning after my favorite mechanic had diagnosed a corroded, non-functional hatch window regulator. A common problem, I know. But he didn't know about the fact that the door latch needs a reset after disconnection, so I looked the problem up on the 4th gen forum and there it was - disconnect the battery. And the hatch latch started working again. But then, driving home the VSC lights came on (horror of horrors, panic, shaking, wailing in fear and all that); and a frantic call to the tech only resulted in confusion again. BACK TO THE 4RUNNER FORUMS, BECAUSE YOU GUYS ARE AWESOME! I made a homemade jumper, followed the TSB instructions, and the lights are off. And I need to be honest about this: if I can do this, ANYONE can do this! Thanks Micablue03, you saved the day! (I included photos to show the OBD connection, and how the TSB directs us to connect the jumper. And, as that amazing homemade jumper demonstrates, no fancy equipment needed!).

I have a 2003 v6 2wd that i like to have fun with in the fields but the traction control is really holding me back. I know there is an easy fix for the 4wd models, but havent been able to find a fix for the 2wd. Please help!

I have done this reset 8 times today. Everything works as stated in the directions. That is, until I put it in drive and start to move. Bam! Vsc lights both come back on. I have no other codes. None. Please help!

Just bought my 4runner and used my OBDII meter to do a pre-buy check. No lights on during test drive before the check but after I bought it and drove away (everything checked out) these lights came on. Gave this reset a try...key step, following line by line... and it worked! Thanks!!!

I cannot for the life of me get this procedure to work.

Over the past year my VSC OFF, and VSC TRAC have been almost constantly illuminated when the ignition is in the ON or Run position. At times the ABS light would illuminate as well. There were periods of time at which the issue would seem to correct itself momentarily. At those times I'd start the car and get no warning lights. By some luck maybe I would make it through a commute without them coming on, then other times the lights would all come back on at a seemingly random application of the brakes.

Currently the situation is such that the VSC OFF and VSC TRAC lights have been on constantly for the last few months whenever the ignition is at ON or RUN, and the ABS light comes on as soon as I touch the brake pedal after starting the truck.

My question pertinent to the ZPC procedure is, if your VSC lamps are constantly on, how do you know if step 3 (the 4 shorts in 8 seconds) has been done correctly? Is there some other light activity that will show?

The shorting must do SOMETHING because if I turn the car to ON, and don't touch the brake the VSC OFF, and VSC TRAC lights will be illuminated. ABS will be off. And if I make contact on the specific pins for more than a continuous second the ABS light will illuminate steady.

I guess what I really need to do now is scan for ABS codes. Any suggestions on a reliable ABS code reader??

But as it sits currently, the ZPC process has yet to even yield a hint of success.. More to follow I guess?

Trac off lights been on a year since I bought my 04 4Runner. Just tried this today, worked first try. Amazing this post was started like 8 years ago and it's still helping people like me. So glad I didn't take it to dealer about this issue I'm sure they would of make some bs up saying I need a $1000 part.

I originally posted this issue on another thread (zero point calibration for 06 4runner?) but have no answers if this is a correct procedure to obtain the zero point on the '07 4Runner.
I think I searched through all related topics but could not find any procedure described by users for 2007 versions. Earlier procedures do not apply (different pins on DLC3/OBD2).
The reason I want to do zero point calibration is VSC TRAC, VSC OFF, ABS, SLIP lights appear some times when making turns. They're off when the ignition is switched on again. CEL/MIL always off.

This is what I found in the BC-21/22 for '06 manuals:
2. Clear zero point calibration.
(a) Turn the ignition switch to the ON position.
(b) Connect and disconnect terminals TS and CG of the DLC3 4 times or more within 8 seconds. (according to the pics: TS - pin 12, CG - pin 4).
(c) Check that the warning light indicates the normal system code.

3. Perform zero point calibration of yaw rate and acceleration sensor.
(a) Procedures for test mode:
(1) Turn ignition switch off.
(2) Connect terminals TS and CG of the DLC3.
(3) Check that the steering wheel is in the straight-ahead position and the shift lever in P position.
(4) Turn the ignition switch to the ON position.
(5) Keep the vehicle in a stationary condition on a level surface for 2 seconds or more.
(6) Check that VSC TRAC warning light is blinking in test mode.
NOTICE: The VSC TRAC warning light stays on when obtaining the zero point.

I managed to get to the 3. (6) when ABS and VSC blinking but VSC does not want to stay on and therefore I'm not able to finish this procedure successfully.

I'd appreciate any feedback.

I purchased a 2004 4runner SR5 with check engine light, tire pressure light, VSC and TRAC lights illuminated. Got a good deal and went to work thanks to this forum. Check engine light mentioned O2 sensor, erased it and all is OKay so far (hoping it was from dead battery). Tire Pressure light was spare, pumped it up and it cleared (yeah-forum mentioned this fix). Rear Washer or wiper did not work (forum mentioned letting rear window down and up -worked-on a roll), VSC and TRAC lights still on (performed zero cal using jumbo paper clips on level surface). Done no more trouble lights-that's what I'm talking about. Nuff Said- this forum = Awesome-Oh yeah wife thinks I am a mechanic (ha ha, I tell her its the internet).

Did this on my 03 yesterday after my vsc lights came on from connecting my Ultra gage. Two large paperclips is all you need. Thanks OP!
