LED side markers - too bright? Throw a code?

The receiver for the tpms sensors is behind the rear bumper cover. The body colored part. My dealership will allow me to replace things like that because they know I won't mess it up and they don't have to worry about me getting upset because they chipped the paint. I told the dealership about the issue and since I have 4 sets of wheels and tires to test with I knew it wasn't the the tpms sensors because the same wheel would error out. It would only happen about once every 600-800 miles which made it even harder to diagnose. I don't like to just change parts so I stumbled on a thread on here that had narrowed it down to the led side markers.

I don’t - but the probability of it happening was very high as I understands it’s the JW LED lights on 2019 and some others randomly.
and since I had a lot of work done on my car and the wheels were off I made it a 1 time event to mess around with them. I don’t have any space as my cars so low to get in there and change them so, figured it’d attempt to stop it if it was ever going to happen...

There is a link in this thread to Amazon for the chokes(post 200). They are a small cylindric unit that has a channel through the center. You just fold them over the two wires feeding the lamp and clip them together. My car is back together now and I do not want to open it up again. There are You Tube videos on removing/installing the lamps. It is not difficult. just takes a little time. You can read through this thread to find everything you asked about.

I just ordered the clear JW for my 2015 z51.
Are there any 2015’s that don’t exhibit the problem?
I haven’t order the ferrites yet. I used to use ferrites on power cords of my stereo system decades ago and found more than one really damped down the dynamics.

I did the foil tape and let you all know about it. Be sure to know that I did not buy the side markers from JW Motorsports. So this fix is no indictment of their product. The inferior product that I bought is why I used tape.

@GS583 Just to confirm - you had the TPMS problem due to the LED side markers and you have remedied, tested, and verified that the ferrite clips in post #200 are the solution??

This morning I opened up the front lamps and installed the chokes on them. The exposed wires were long enough that I could fit the smallest chokes on them. The only one that I used a larger choke on was drivers rear as I chose to not remove part of the wire loom to allow the length to be enough to fit a small one. Your cars wiring looms may be slightly different.
BTW, you place the chokes over both wires and clip them shut.
Best of luck to everyone that has been having issues with this and hope it is a good fix for you also.

I forgot to test this morning but I did put the chokes on this weekend and no TPMS issues but I did not force my lights on.... I will check tonight on the drive home and hopefully remember in the morning also... So far it good to go...

I was only able to use the very small one on my front left light as the loom was further back the other 3 I used the next size up that fit exactly over the wire and loom.... I also used a 12 inch piece of electrical tape over the choke just to make sure it does not fall off some how some way...

So far, no luck for me with the ferrite rings. I purchased the set from Amazon but I have only installed the one on the left rear marker wires. I get the TPMS system default code within a few minutes of driving on the freeway with the lights on. Does anyone have an opinion on whether or not installing the other three would make a difference? I can try it if you think that would help. If not, I will go in another direction.

I think all 4 chokes were installed on all four corners and the "fix" worked.

Mine was the one that happened to work by installing on the left rear only BUT I did install the other three the next day. I would suggest installing the rest as all of them will emit RF and one may be worse than the others. Best of luck and hope it works for you. BTW my LEDs were from JWM . If yours are from somewhere else there may be differences.
