VSC trouble after 3 - 1 lift

After installing a 3/1 leveling kit, with uca's I now have my PCS, slip indicator, radar cruise control malfunction and trailer brake error all staring at me. HELP! 2018 d/c

 

Cables are all good. All the warnings disappear with a key cycle but show back up after 15 - 20 miles.

 

You probably need a zero point calibration done. Toyota dealer can do it. After I lifted it myself, I took it to big o tires because the alignment dude was a Toyota guy and new how to do it. There are threads on the forum on how to do it as well.

 

We did a 3/1 on my 18 with no issues.....I did not do UCA's though.....It was done at a Toyota Dealership...wonder if they would have done a zero point as part of the install?

 

Most likely. The traction control system on our trucks are very sensitive. If you don’t reset the parameters with the new lift, the computer senses that something is different and causes all sorts of issues. I would look up the procedure myself but I’m at work. I know there’s a thread on it though.

 

Gotcha...they must have as I have had zero issues with the lift.

 

Going to have a zero point done on wed., will let you know the results. Thanks

 

+1 on zero point calibration

 

I'm not sure if it's been mentioned in this thread yet, but its probably ZPC.

 

Had the zero point calibration done by the dealer. Drove 5 miles and it happened again. took it back and they are trying more stuff now. Hope they get it , leaving today on a week long hunting trip.

 

There was someone else here that had this issue and could never correct it even after going to the dealer. I think he ended up removing the lift. Try to do a search. Ill see what I can find also.

Edit: it was @Joeshaker

 

Stretched ABS Wire?

 

After the dealer recalibrated the YAW sensor I drove 95 miles then it started up again. Now it comes on at no certain amount of miles, 5 - 30. Sucks when it constantly flashes on your dash.

 

I'm guessing it's something else. A really close inspection of ABS sensors and wires might help. I lifted my '16, changed UCA's (twice) and haven't had any issues.

 

We lifted my 18 with no issues....I'm guessing its something else as well....

 

Just received a call from my dealer (truck not what you were thinking). they talked to engineers in San Antonio and were told that a componant on the air bag system is bad. The part that needs to be replaced is on a back order status. Apparently the a lot of the early 2018 model is having this problem.

 

good to know.

 

I was told it is the SRS computer. It gets information from the YAW sensor. The computer itself is failing.

 

Subbed. Looking into about a 2.5 1 lift with uca. But I definitely don’t want any issues with the VSC. Had issues with that on my 2011 tacoma and it was scary ass hell, when the abs would lock up your front wheels when going around a corner!

 

Please keep us updated @birdslayer

 

Saw this thread and had to sign up to post. I am currently going through this issue with mine as well. 3/2 level, on a TRD 4x4. None of this is the issue as a non lifted truck was there as well with the same issues. They did ZPC on as mine as well to no success. Dropped it off yesterday for the second time in a week. I've seen a video on YouTube, where a CHR was having the same issue, minus the trailer brake.
With all that being said, there has to be an issue with the way they put all the features together in the TSS-P package that would be causing the issue. That's my 2 cents on it and I hope it helps you to know it's more widespread and not just yours.

 

Welcome from CO. The zero point offset alert isn't always triggered when adding a lift but, that being said, when the alert is triggered the ZPC is performed. The problem is that it doesn't always work. The YAW sensor can be shimmed back to level and then redo the ZPC. My .02...

 

It's happening to vehices without lifts as well. So, I really don't know, and I'm not a mechanic. I do know that they cleared memory and re calibrated mine and it still did it.

 

Yeah, in those cases something weird is going on. If the memory is cleared and ZPC and still doesn't work...possibly bad data is being sent to the computer or a computer reflash...maybe......

 

This guy posted 3 videos on YouTube where they changed all sorts of stuff on his CHR and it' still doing it. I know it's not a Tundra but with same TSS-P system and getting same errors, I'm thinking it's something there. https://youtu.be/pAzHXEm6c4Q

 

Hmmm....definitely a possibility for sure. Now I'm kind of glad my 2nd gen doesn't have that nanny. I forgot about the pre-collision sensor on the 3rd gens..

 

I just ordered a 4” lift. Now I’m scared to even try to install
It

 

The computer finally came in. It will be replaced on 1/2/18. I will let you know if it takes care of the problem. I would check with your dealer about this.

 

The follow on video to the one posted above shows the end result. Dealer had it for a month, changed several components without success and finally fixed it by replacing a faulty ABS ECU. I wonder if Toyota puts out tech bulletins or similar to help streamline the diagnosis and repair process at other dealerships.
