has anyone reversed the headlight wiring recall?

I had the headlight wiring recall done on my 2021 sr5 with halogen lights. Headlight lighting was mediocre before, but since the recall was done it s downright dismal. If I understand correctly the low beams and high beams no longer stay on together when high beams are turned on. Has anyone reversed this recall? Was it DIY? If not doable and I install an LED replacement bulb will it still shut off low beams when high beams are turned on?

 

It would be difficult to reverse the recall. They cut into the harness and splice in relays on each side.

 

Sounds like a good candidate for OEM LED replacement housings and an @iHacker harness.

 

I figured as much, they should have given us an option to upgrade, for a fee, to the oem led headlights instead of butchering the wiring. I think they also forgot to reinstall the plastic harness shielding on the passenger side of the engine bay, the wire bundle next to the shock tower is bare with some electrical tape wound around it. Wish I had taken pics of my engine bay before I brought it in for service. I m not impressed. Lighting after the recall may pass DOT code, but barely.

 

It can but done but wont be fun. A few months ago I posted the instructions for the "fix" form Toyota. I would have to go look it up but I guess it really depends on how bad you want to undo it.

 

thanks, went to the dealership today, they won t do it and told me not to do it, so I won t, warranty and such, so instead I ve ordered some well rated leds off Amazon,
2022 Upgraded AUXITO H4/9003 LED Headlight Bulbs, 100W 20,000LM Super Bright, 6000K Xenon White, Halogen Replacement with Fan
, that several members here praised, and failing that I ll pony up the dough for new oem led headlights

 

Oem headlights are definitely terrible been wanting to upgrade to the OEM LED since new. So after the fix the lows are even dimmer for sure? I was thinking the only difference would be when the highs are on (and thus no light difference). I wonder if there would be an issue if people did not do the fix but switched to OEM LEDs (you’d think there would still be an issue when the high beams were on)?

 

The only difference after the recall is that when the high beams are on, the low beams are no longer on (which used to be helpful given how weak both the low and high beams are alone). The relays and connections they add to the wiring also add some minor resistance, a few ohms, so you d lose some brightness there too. The entire problem stemmed, as I read on NHTSA s website, from a dozen or so Texas oil workers idling their trucks for hours with both low and high beams on, and the heat starting fires/ melting wiring, but Toyota s solution was not too bright I m thinking the oem leds use under 60/55 watts, which the halogens use, and probably have a fan or at least a heat sink (someone with oems leds could chime in and confirm) so overheating is not a problem with oem leds and the recall "fix" unnecessary (Note that the recall only applies to 2018-21s with halogen lighting only). That s the route Toyota should have taken, upgrade recalled vehicles to oem leds (but $$$).

 

Ah yeah that makes sense. I will attempt to avoid the recall then and go the OEM LEDs. Heard the dealer will sometimes do the “fix” without asking, mine has not yet even though have had several times.

 

Just joined to ask some questions regarding this issue. I've always found that having a low beam on with the high beam is distracting, and I think this is the general idea on most vehicles.
I took my 21 dc long bed halogen in for the recall and the dealer said according to the label on the harness no action was required. They couldn't give me a straight answer and neither could Toyota Canada. I figure the only fix would be to install relays to cut power to the low beam circuit when the high beam circuit is energized, but decided I use high beams so rarely that I'd just leave as is.
Don't mind the halogen bulbs, they're simple and inexpensive and I could upgrade to some higher wattage super whites if I felt i needed more light. I've had motorcycles with halogen lights that put LEDs to shame so, all good with it. I'm also glad I have an actual key rather than push button start, I think it's far more secure.

 

If they did not perform the recall it means your wiring already separates low beams and high beams, so if that s the way you like it, leave it as is.
I went with these:

And left the wiring alone

 

No the low beams stay on when the high beams are activated.

 

try going to another dealer if you really want the relays installed, the recall is to "remedy" exactly this

 

The recall was stemmed from the manufacturing of the harness in Thailand. I posted that info a while back. I would have to look to see if it mentioned anything about labels. Some of the dealers are clueless and some have done some some real hack jobs on the relay installation.

 

Yup, my dealer seems clueless and after reading some posts in this thread I'm happy to just leave it as it is. Taking my truck to the dealer for anything I can't wait for is insanely inconvenient for me.
