Hello,
I have a 2011 SR5-Premium. The horn wasn't working, so upon dignosis, I replaced the clock spring/spiral cable with an EBay replacement for $35 vs. $500 OEM. I know the risks involved.

After I reinstalled everything, I noticed that the VSC "Skid/Swerve" light and steering wheel light with an exclamation mark were on. I tried to reset the code using the Zero Calibration method by jumping the OBD connectors to no avail.

From there, I disassembled the the steering wheel once again and boom, there it was, a small wire harness on the bottom of the CS assembly that i failed to reconnect. I reassembled everything and the lights disappeared!

Until a mile down the road. They both came back on, steadily lit. I drove the truck 30 miles with no issues.

I read on these forums that the lights are not easily cleared and usually have to be done at the dealer.

To avoid that trip, what should I do?

My Questions are:

Which code readers are capable of reading/resetting these lights?

Will TechStream be able to read and reset it? I have a Sequoia as well, and would love to use that software on it.

Do you have ANY input for me!

Here is a link to a video of what happens during Zero Calibration:

You must clear the old data prior to performing the calibration.

The procedure document is attached. Read through the steps several times and plan ahead; note that the final step requires driving straight at 25mph for 10 seconds.

Get yourself a mini VCI and a copy of techstream even if this event is cured with
the jumper method, it's a must have item if you are going to own and work on Toyotas.

You can always try disconnecting the battery for 10 minutes and then reconnecting it. That might work if the cable isn't broken.

First, thank you for taking the time to help. The spiral cable came with a tab that needed to be broken off before the install of the steering wheel. I imagine that was what kept it in place. Otherwise, no, I did not wind it up. Here is what it looks like. notice the orange tab.

I am printing these directions right now. I have read before that the codes MUST be cleared. I was searching for these directions! I really appreciate it! I will report back. Thank you, again.

And yes, I need the TechStream!

I actually let it sit overnight... Thank you, though.

No problem. Get it fixed?

Not yet. I just got the TechStream items in the mail.

Dang well good luck man

So, I am "unsuccessful" in trying this reset. I used the Techstream program. I followed the directions the best I could, other than the fact that I was unable to drive for 25mph for 10 seconds.

However, the VSC light never flashed upon the reset process. Only the ABS light did. When I jumped the terminals with a paperclip, the light DID flash.

Also, using techstream, it states that I need to select the "Skid Control ECU" to clear the Zero Point Calibration. I cannot find that menu. I feel like that may be the missing link.

Any input is appreciated. I will be trying again in the coming days. This is frustrating!

You MUST clear the old data:


(7) Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Reset Memory.

(8) Select the skid control ECU to clear the zero point calibration data using the Techstream.

(9) Turn the ignition switch off.

This is killing me... I cannot figure out how to get these lights to turn off after replacing the spiral cable on my 2011 Trail Edition.

I've followed the instructions step by step and keep hitting endless loops where it says if the slip indicator light is not blinking, do it again... I gave up after repeating it 3 times in a row with no change. I also tried to push through the full document regardless and still exactly the same as when I started.

After I replaced this part the first time I took it to my local shop, they said they were getting an error that made it look like it was a hardware connection issue. Got and installed a whole new spiral cable and wanted to get more info so I bought a cable and got a copy of techstream.... Now I've wasted hundreds of dollars and tons of time and I'm still right where I started.

Anyone have any additional help or guidance to figure out how I can fix this? My vehicle inspection is now expired and I can't get it renewed until I fix the lights.

You ever get this fixed?

I have the same issue. My tech stream won’t clear the errors. Any luck taking it to a dealer to get cleared?

Took it to the dealer. They won't clear the codes.

Want to sell me a new Clock Spring for $1300.
