Hello, If you have a kick sensor on your NX 2nd generation, I'd really appreciate if you can send me a photo under the driver side of your rear bumper. My car did not come with the sensor but I bought the part with a parts credit that I negotiated to be included with my purchase. I will report back to see if it ends up working on models that did not come with it to start. The dealer was unsure so it's a gamble I took and am going to install it myself. I believe my car may be missing a short wire the sensor plugs into under the pumper on the driver side. If anyone with a kick sensor can snap some photos under their car I would really appreciate it. I am looking for where the wire plug originates from that plugs into the end of the the kick sensor. Here is a photo that may help.

 

Typically there are many components required for the kick sensor to work.

There should be a computer controlling that. The wireharness is different. Then the main computer needs to be programmed to work with all other sensors such as proximity and your instrument cluster.

I doubt Lexus would have provided all those and left out the sensor only

 

do you know any of that for certain or did you just make that all up based on your opinion of what you think is the case. It’s an additional switch to something that already had power
open and closed with a second switch. Do you need a computer to install an additional light switch in your house? Why make a comment when it’s clear you don’t know what you’re talking about but speak with such authority like you do? Please refrain from commenting when you have no clue. This isn’t the first time you responded to a thread I posted with an uneducated opinion stated as a fact. Btw you were completely wrong about it being impossible to add a key card when your car didn’t come with one despite you basically saying the exact same thing you’re saying here (ie. need additional hardware installed from factory and computer).

 

I believe it was digital key. Did you add one?

Prove me wrong with data, not statements please.

 

Please just refrain from responding to my threads in the future. You are always the first to respond and incorrect but state as fact like you know what you're talking about.

 

Love that Aloha spirit.

 

Yup, I have aloha spirt for the other people that read this in the future that trust the incorrect information being thrown out that will ultimately decide they can't add it when they can. This isn't the first time this has happened which is why I don't have a lot of patience for it happening again. Many people in the future will read this thread and believe the first comment written on them telling its impossible. Would you prefer nonsense being spread as facts go unchallenged and the forum become useless because it has more misinformation then CNN? If this was the first time this happened I wouldn't say anything but the other thread I basically had a copy paste with the exact same lame excuses that also turned out to be incorrect but were stated with the level confidence you'd expect from the head engineer. Then the guy demands I prove with data that he was wrong when he gave none. The proof is I accomplished exactly what I wanted to do in the other thread which he claimed was impossible due to "missing hardware, factory programing...." the same reasons he gave above here. The aloha spirt is not letting people destroy a forum for everyone else because someone wants to sound like they know what they are talking about when they don't. Would you prefer someone to pretend to be a doctor and give out medical advice with the confidence that they are one? If I don't know what I'm talking about I don't chime in.

 

There are five variations of the wiring harness in the back depending on which options are present. One of the factors is the kick switch. Pretty likely you'll need to get a harness to make this work. I crossed this with information from TIS and EPC. This is not the first time I've seen this with Lexus vehicles. I have illuminated kick plates in my IS F, but the wiring to support it (which is in the IS350 luxury model) is not completely present.


OTOH, the parts for the rear power shade for the GS F (not a US factory option), can be purchased and then plugged into the existing harness and it all works like it came that way. Perplexing and frustrating for sure.

 

Thank you for this information. It's my understanding there is some Y harness you can add inside the driver side of the trunk. I haven't confirmed it yet but am trying to. If this isn't the case then almost certainly they have a blank unused plug that is capped off that can be plugged into. I would imagine whatever wire goes to the trunk open button on the trunk gets a Y harness splitter added that connects to the kick sensor on one end and the trunk button on the other. TIS and EPC must be some sort of parts diagram software that shows the info based on the VIN or trim level I gather? I've done a lot of work on BMW's and was able to find the parts diagrams from my VIN online rather easily for my BMW's compared to Lexus as there is a website I just put my VIN into that then has all the diagrams for everything. Thanks a lot for this information

 

It's certainly possible there is a hack for it when you don't have the harness you need from the factory. That's how most guys have wired up illuminated sill plates on the IS F. The good news is, none of the ECUs are option specific, so they're all running the same code, and the door is controlled by the body ECU. It just looks like no one on CL has done this yet.

If you want to see all the repair information, you'll need a TIS account. They have relatively inexpensive short term subscriptions for the public. I have a full professional annual subscription because I have three Toyota products in my garage and I service all of them myself. Most people don't do this unless they have a repair business.

 

Thanks again, just saw the part numbers you added. The part is cheap so I'm just going to order it before I take it apart. I'm thinking of also adding the parking sensors as well. I was told my vehicle had it but turns out it didn't Since its the same harness it should be much work to install that as well. Since no one else has done this yet I will document the process with photos and upload them so others can try in the future. Yes I believe you are correct on the computer code not being an issue either but have not confirmed it yet.... the reason being someone with a RAV 4 added a kick sensor and the computer automatically realized and allowed the setting to be used. I will confirm this when I do it but suspect it to be the case as the RAV 4 is very similar obviously and the part looks identical,

 

Hum, you bought the part (with your "parts" credit) but have no idea how to install it (make it work) and tells someone who leaves a post which sounded reasonable to me to take a hike. If your NX came without the kick sensor who knows what other parts are missing/needed, I doubt it's "plug and play" as complicated as the new NX is but that's just my uneducated opinion. My first move would have been to check with your Lexus dealer before buying the part. Sounds like the one that has "no clue" is you.
I know---------------------------- don't respond to your threads.

 

Your first move is probably isn't my first move.... I got $4300 off a custom order NX350h during the peak back log time 8 months ago when nearly everyone else was paying over MSRP. This was when there was a 12 month wait time on the 350h at my dealer. Also got roof ranks, all weather mats, sunshade, touchup paint, oil, free wheel locks, and several other items in addition to the money off and parts I requested. I'm pretty sure I made the right move getting free stuff thrown in for free. If you wanna trust your dealer on info go ahead.. thats how I ended up without the kick sensor because they gave me wrong info. You'll end up paying some entry level tech guy to break several things when they install it and youlll be out 2 grand when I got mine for free. I've done enough work on my cars over the years this will be like brushing my teeth. This is really basic stuff. I'm just trying to get info from people that actually know what they are talking about rather then just chiming in cause they're bored and need to kill time while their wife's bf finishes up! Its better to know what your doing ahead of time so you don't end up missing a $5 part and having to drive around without a bumper on your car for a week waiting for the part to arrive.

 

Let’s keep things polite and mature here please, or do not post. You can question or disagree without calling someone out

 

Pretty strong attitude here when you're asking someone to do you a big favor and crawl under their car and take a picture.
