2013 TCH DRL/High Beams not turning on

Hi,

I had aftermarket LED installed in DRL/High Beam, for almost 11 months, they just started showing weird behavior since past 2 weeks:

Sometime my DRL don’t turn on (both sides), with that my high Beam also doesn’t turn on. It was random sometimes they do work fine.

I thought it was the aftermarket LED’s so I replaced them with brand new ones, now its not even turning on.

I put the old LED’s back, not turning on.

I put my old halogens, not turning on.

* Just noticed that after couple of starts and stops and driving it turns on, but its inconsistent.

Not sure whats the problem, i tried looking at the manual to see if its a blown fuse, but there is no entry for High Beam bulbs fuse.

Can someone shed some light?

I think it's #10
10 H-LP-MAIN

Otherwise, DRL is hardwired into the headlight relay. DRL is said to still run even with fuse removed. Safety measure.
Do you have 12V at the plug? If not, your headlight relay may be damaged.

Try this, said to be generic to Toyota:

Open the glove box. Locate the headlight module at the back of the glove box. The headlight module is the black unit mounted sideways with a wiring harness connected to its side.

Unplug the harness from the module and pull the module out of the vehicle.

Ok thanks.

Right now the drl and high beams are working constantly, have started and stopped the engine multiple times since yesterday, this led me to believe that it may not be the fuse, also the steering selector is set to auto so it is not the selector switch.

I am leaning towards a relay issue. Now i open up the engine fuse box (it has 3 relays on top left side grey color) the headlight rely is the bottom one, i am thinking about either swapping it with each other (they all look same) once the problem is happening or just replace it right away.

Any suggestions?

Ok, so here is the update, car was running fine with the original halogen's for 3-4 days. I felt comfortable to put my LED lights back on, so I changed that. They ran fine, no issues at all. Not sure what the problem was.

BTW I did plug/unplug my relays, re-inserted the low beam/high beam cables just to make sure they are not loose.

So after all the car is running fine for the last week or so.

Problem re-appeared, but I found the root cause :)

Ok, so the car ran for almost good 2-3 weeks, before my High Beam/DRL stopped working again.

I tried the usual, replacing LED's with Halogen, NO go, even OEM halogens weren't working. I used the multi-meter to test whether the plug is getting any DC voltage, it shows dead, no voltage.

I then opened up the fuse box and was just looking to see any magic to happen, when I accidentally pressed against one 10AMP fuse, and boom............the DRL turned on, I pressed it again and it was gone, pressed again hard, it came on.

It is this Fuse in the picture: Can someone comment on whether I need to replace the fuse or something else? Also what is the purpose of this fuse?

Sorry for bringing up an old thread but My 2012 high beams suddenly quit working last night. Did you ever figure out the fix with this fuse in the pic?

Hey,

Sorry for the late reply, been busy at work. Since I pressed the fuse, I didn't have any problems, but just for the sake if anybody else has the same issue, what do you exactly mean by curving the fuse blade? See the pictures below, which one do you mean, 1 or 2?
