Leveling Kit Caused Issues Related to Front Facing Radar - Help please

[Po-Jay]

#1 "Leveling Kits" are festooning and vanity for assclowns and high schoolers trying to get attention.

#2 It's not surprising the "Leveling Kit" causes your safety and cruise control radar to go wonky with the new position of the front end.

#3 To fix the issues remove said "Leveling Kit" so the safety and cruise control radar now works and people dont think you are an assclown or a high schooler

First of all, EAD, Douchebag. I asked if anyone had experience with this issue. This ain't my first rodeo. And thanks for making my first few posts on this forum so damn pleasurable. I absolutely love internet toughguys with such heavy keystrokes.

To anyone other than the dickbag that I quoted...

I put a 2-inch front and 1-inch rear kit on the vehicle. IMO, there is way too much wheel well in the rear. I am not towing a boat, so I wanted to make the stance look better. I am not the first one or even the 1001st one to do this. The issue at hand is that only some of the 2020's have this experience. There are 4Runners on here with way more aggressive lifts and rake changes, that do not experience this issue...

I am working with Toyota to recalibrate, but they are absolutely clueless on how to do it. So far, service tech is not much help...

I appreciate your thread.
Now, I will have the dealer deactivate all this shit before I get used to it.
Let me know what they used/did if you go this route.

Soon, we will wonder how we drove all these years prior to this I-Nanny stuffy.

I tried resetting the ECU to no avail... I am taking it in tomorrow morning to have the Radar deactivated... I would like to have it recalibrated, but my Toyota dealer seems to think it is impossible... With any luck, a fix will become available in the upcoming months and I can turn it on again.

As a native Floridian, your stated location of “NJ/FL” comes as no surprise.

The absolute scum that chooses to relocate to FL from NY/NJ is mind boggling. Self entitled, obnoxious idiots is a very fair and accurate broad brush. You are the living, breathing embodiment of the well earned stereotype.

By unplugging the battery for 30 min? This could help. I would check for any disconnected wires. If it had no issue after the lift, it could take up to a few hours to throw the error. If you got the alignment days later, then it seems it would be something underneath that the tech must have done.

I had Eibach 2.0 front coilovers installed a couple of weeks ago. Had the shop set it basically level, maybe even .25” high in the front in anticipation of a small lift in the rear. Took it off roading this weekend pretty well loaded in the rear, meaning there was additional squat. Was concerned I might see some TSS issues but happily all worked fine.

Mysterious how this issue only affects some vehicles. Could this be an SR5 vs ORP/Pro thing?

PO-JAY -
RE the ABS Light. If you watch any of the 4Runner youtube lift installs, there is an ABS cable that needs to managed so it doesn't get cut, while installing the lift.

Wondering if that's the cause of your issues?


I watched a bunch of those videos and decided that I'd let a professional install my lift. Too many ways to kill myself doing it by myself.

Wow... The drivers side wire is severely crimped and I hadn't noticed it. I actually had a local shop do the work, since it is cold as hell here. I should have done it myself. I appreciate the suggestion to look at it.

Figure that Pre-collision system is ABS related.
Hopefully not too expensive of a fix.

I'm another 2020 owner with a lift... 2 and half inches in the front and a little under 2" in the back on Bilstein 5100s. No tss problems. Hopefully it's just the ABS cable. The shop that installed my lift had a lot of experience and does their alignments in house. (Stellar Built in Sacramento) They may have an insight into your problem. The Toyota dealership in Walnut Creek CA sells new 2020s with installed spacer lifts (with a hefty markup), so they could have some info on potential tss issues.

Pro-Jay- I believe there are threads dealing with the ABS wire. Others have damaged theirs and I think they posted the part #'s and sources for replacement. I don't think it's all that expensive for a DIY repair. A quick search should get you there.

It will be fixed tomorrow. Outside of a ton of my time spent chasing the Radar Calibration with Toyota and aftermarket companies, there is no cost thus far. The shop that installed my lift is ordering the part and fixing the cable, at no cost to me. I literally checked this forum 30-minutes prior to my appointment at Toyota. I really thank you for the response. It potentially saved me several hundred dollars.
I will post again once the cable is fixed. Thanks all!

Pro-Jay you might want to check the other wheels for taught or damaged ABS wires as well; if you haven't already.

The only one that seemed to be damaged was the drivers front. I think the asshat that worked on it, learned pretty quickly, but decided to NOT say anything... Thanks!

You're welcome.

See, now that is funny. :rofl:

Well, the issue is fixed. The ABS wire was the problem. I appreciate the help with this.
That wire is really easy to screw up, doing suspension work. I would be willing to bet that it is the issue for most of these problems.

I currently have the same problem but didn’t pop up until alignment was done. Shop said they had to zero the steering angle through OBD. That’s when problem started. Drove with front 1” spacers on then full lift for a while before alignment done (several hundred miles).
Deciding on whether to install factory suspension before dealer visit or not.

Been doing a lot of research finally found this thread and I'm currently dealing with the same issue!

I have a traction light and front radar collision light on. I have been to shops and finally the Toyota dealership. They installed a new radar sensor in the front and came back with some excuse as to why they couldn't calibrate. Nobody has been able to figure it out. Spent close to $1500 so far chasing the issue. Now, I believe my issue is the ABS wire as well because the last shop told me it keeps throwing ABS codes which is why the front radar sensor won't calibrate.

My vehicle was hit on the driver's side and I had to replace a driver control arm, the driver fender and headlight.

My question is which ABS wire did you have to replace to resolve the issue?
