DRL can't disable

[Luciefer]

Read some topics how to disable DRL, but can't understand it. I don't want to disable auto-on, only DRL.

What i must to do here and where? How i understand, it is under the hood.

^^^ wrong place. You need to get in under the ac in the console. There is a yellow wire that you need to cut. Will disable the auto on feature which eliminates the DRL, but you dont lose your high beams. Look under the installs section there are two step by step guides.

The auto-on system and the DRL system are one in the same. You cannot disable one without disabeling the other.

:werd:

[Luciefer]

huh, i like auto-on, but don't like yellow DRL :(

[dachusa]

well it seems your only option is to disable high beams then, or mess with your electrical until you happen to stumble upon a new way.

[JOHN_B]

All you need to disable are the high beams. Cut the wire located near the shifter/under the A/C console.

[LEDmod]

There is a way to diable just the DRL...
But you have to cut the wire from the ECU....
PM 2way, he told me while back, but don't remember now..

[Luciefer]

I don't want to disable high beams, because I need it :). I want to disable just the DRL.
It must be some way to do it...

[LEDmod]

Where's that combo meter for me to look at? I'm gonna send you a bill :rofl: Let me look @ the circuit & see what I can come up with. You do know that the DRLs are the HiBeams, but @ reduced brightness? If you have an early MY, have you done the DRL recall?

Off to read the schematic. I'll update you.

UPDATE: The Lt. Blue w/White tracer wire.... off Body ECU Connector 'B', pin 17 is the DRL RLY2 control wire. This goes to ground to activate the DRL's when the parking brake is released. However, DRL RLY2 also needs to be activated in order for the high beams to work. The mod allows this relay to only be activated when the HLs are on... so you don't want to do that.

If I understand what you want... here's what I'd do... & what you'll need:
(2) 1N4001 or 1N4007 isolation diodes
(1) Switch (I found a nice one that fits the OEM hole... if you search)
(1) 3M Red Tap
about 4-5ft of wire
some heat shrink tubing various sizes


Cut the Lt. Blue/Wht wire previously mentioned. Slide heat shrink sized to cover both diodes over this wire. Solder the anodes of the (2) isolating diodes to this wire.
The cathode of (1) diode goes to 3.5-4 ft of wire to the added switch - the other side of the switch goes to GND. Slide heat shrink that will cover the diode to the wire.
Install switch and ground
Solder an approximately 1 ft piece of wire to the cathode of the other diode. Slide heat shrink that will cover the diode onto the wire.
Heat shrink the (2) tubes on each wire over each diode.
Slide the 1st larger heat shrink over both and shrink.
Using the 3M Tap, tap this added wire to the thin Red w/Lt Blue tracer wire that is the HL relay control... located in the bundle on the lower left side of the center console just ahead of the accelerator pedal. Make sure you have the correct one.. there are a couple of Red/Lt. Blue wires in that bundle.
QED

Here's the circuit description:
Note: you lose the brake light control of the DRL's

Your new switch will control DRL RLY2 instead of the Body ECU.

The Celica's HL RLY control from the Body ECU will also control DRL RLY2. Thereby, not losing your highbeams when the HLs are on. The HL RLY, via other means, defeats the DRLs. Hopefully, the Body ECU should be able to handle the minimal added current of the additional relay coil. QED

If that's a concern.. you could do it by adding a relay to the Body ECU HL output to control the ground to both the HL RLY & DRL RLY2 wires. Easy for me, as I have remote control of my HLs via my alarm and an outboard relay;) But the 2 diode method is just so slick... & I know how you love diodes.

Where should I send that bill?
:thumbup:

[VoodooTRD]

just unplug the DRL sensor plug under the driver side dash.

[delija_16]

I think i'm the only one who actually likes the DRL, and the fact that they are yellow. If the DRL is a high beam at 30% or so, can't you just go to autozone and buy those coolblue bulbs and replace it?

[tigerjj85]

before you start the car, put the e-brake one step from bottom, and then start.
It won't turn on the DRL!!

[GTJeff]

Is that True!!?, that must mean the running lights operate off a ground wire...much like the DVD player I installed a year ago

[LEDmod]

Then you'll have BRAKE light on all the time..... :D

Yes... but than your highbeam will be blue too...
I don't know about other states.. but I got a ticket for that before
blue parking wedge bulbs..
Anything that's not amber, yellow, white in the headlights are illegal here
btw Dooly, those bulbs work great except I can't use em anymore..

[tigerjj85]

Pull the BRAKE light led from the cluster.
That will solve the problem.. :gap:

In Las Vegas, cops will just tell you to remove the blue bulb, but no ticket....

yeah.. the cop was not anal.. but gave me ticket..
I leave right behind the district court.. literaly
I said I will change it in front of him but he said no..
oh well i got my money back tho..

[phillycheese917]

Wh ydoes everyone say cutting the yellow and green wire disables high beams. I cut it and it disabled auto-ons and DRL and DIDN'T DIASABLE my highbeams. My highbeams work perfectly fine.

loll...well do you realy need to use your high beams ever? and since the drl runs on 30%, light output wont even be blue, it would be white (at least that's what i think, correct me if i'm wrong) and since the bulbs themself are weak with the 100% they would be hard to see anyways. The easiest thing to do if you don't like the drl, get the bulb out...loll

matter of fact.. I use highbeams all the time
I live in the rural area and it pretty often someone hit a deer or something
last time some diikhead put a trashcan on the road and my friend did not see it. (not using highbeam)
by the time when we saw it, it was too late to stop. so he swerved to avoid
hitting it and he ended up totaling his less than a year old WRX and neighbor's truck parked in drive way too. and we both had to go to hospital

Use highbeams.. it will save your life and car!!

[Babyboi419]

dont kn ow if u done it yet..i might help..i think every model is different if im not correct? i have a 04 celica...and i disable mines...in the fuse box next to the hvac unit...you are cutting the *number 18 wire..and it should be a yellow and white stripe put together..thats how i disable mines

[VoodooTRD]

just unplug the drl sensor. and if you want drl back on just plug right back in. easy.

no need to cut wires.

I was told in driving school not to turn on my high beams in the area full of deers, because it just attracts them even more, Just get your self an HID kit and you'll see more and drive according to the spped limit and you should be fine ;)

where is this drl sensor?

[VoodooTRD]

where is this drl sensor?



just unplug the DRL sensor plug under the driver side dash.


its the circul looking bubble located on top of the driver side dash. right where the windshield and dash meet. to unplug the sensor just look under the dash and un clip the sensor.

[Luciefer]

I did it. After this worked only DRL (always, day and night), auto-on not worked.
This is "automatic control light sensor".

[Celica402GTS]

I think i'm the only one who actually likes the DRL, and the fact that they are yellow. If the DRL is a high beam at 30% or so, can't you just go to autozone and buy those coolblue bulbs and replace it?


i used to not like them..so i cut the wire..then now i rewire it back cuz i'm too lazy to turn the knob that turn the headlight on at night..it's good to have full control of ur headlight cuz when u go somewhere at night and u don't want people to see u pull up, u can turn off the light..but with auto-on..u have to turn off the car, pull ebrake to one click..start the car again..especially at spot where u go to race in the middle of the night..

[PhReEk]

how about doing this as an alternative ... not sure how to do it, but maybe someone could figure it out :::::

wire your DRL's to work off the parking light (the little wedge bulb in the high-beam's reflector) and get a set of hyper-white led wedge bulbs... you'll still have DRL's but they won't be yellow and hopefully you won't lose your high beams either...

is there a separate wire that only carries the 30% voltage to the high beam bulbs? or is it a relay that changes between voltages depending if the DRL's or high beams are on?

[PhReEk]

upon further investigation... looking @ page 11 of the electrical diagram... there is a relay that controlls the headlights... the outputs of this relay run to a 7.5 A fuse for the DRL's and i think it's 2 separate 10 A fuses for the high beams (in the diagram they're called HEAD (LH/RH) LWR, which i believe would mean LOWER HEADLAMP, which is the high beams)

so couldn't you find the single wire running from said 7.5A fuse to the high beam and cut it, and disable the DRL's while leaving the high beams alone?

and, if you wanted to do like i stated above, tap that wire from the 7.5A fuse into the wire for the parking lamp?

edit: it's more detailed on page 25

I cut the yellow green wire, but DRL and Auto-on still working.
UPDATE: ups, I cut another wire :)

do we have to remove the dash?

[Luciefer]

do we have to remove the dash?
I try it. DRL was working always, auto-on didn't work.

Cut yellow w/ green wide. DRL and auto-on isn't working. I think, may be so better than only disable DRL, now i can be without light at night.

[VoodooTRD]

no, stick your hand underneith the dash.

i just cut the yellow/green wire behind the a/c controls and wired it to a switch. now i can control whether my auto-on & drl's work or not by just flipping a switch.

have you tried to check the installs?

no pics :(
maybe i should do a write up on it? but it literally took like 20 mins. basically cut the wire and hook up the switch, then drill a hole in one of your empty spaces on the dash and put in the switch.
really easy.

[BlueRice]

OR, you could just go down to the dealer, who disables the DRL perfectly for a whopping $40.00 (at least in my area).......oh, and its warrantied that way as well.

[jotun666]

I tried the dealer riute. they spat out some **** about it being illegal and wouldnt do it. Even though i had the TSB in my hand. no idea why...

Also, does cutting that wire behind the dash disable your fogs? cause i read somewhere that it does.

[VoodooTRD]

No it doesn't. It just prevents the sensor from telling your headlights to turn on.

Why not just uplug the senor like i mentioned under the dash. its in reach and you dont have to remove the dash.

[GTJeff]

Where is this sensor you speak of? I looked under the dash and don't see it, is it a clip??? Anyway i can get my Foggers to work independently from the headlights being on? Like...Foglighs are on, but the headlights are not.

[VoodooTRD]

look on top of your driver side dash. you will notice a circular thing on the edge of your dash. right where the dash a winshield meets. thats the sensor. no under that is a clip/plug you can unplug to prevent your drl from turning on. you will have full control of your headlights.

as for full control of your fogs only, dont know how to do that. you must have your headlights on in order to have your fogs lights turned on.

^^ INSTALLS section

[GTJeff]

that is one difficult plug! i was under there for a few minutes, car is way too hot to do this right now, I was getting burned from all the throttle linkage under the dash.... ill try again later, one stubbern plug, Can you get it out through the top, i pushed the lightsensor up outta the dash.

I just disconnected this sensor and it disabled my auto on feature but my DRLs still work.

[GTJeff]

Okay I found it! I tried pulling it out and the thing is stuck, what did you use a screwdriver or something, man it is soo tight under there its crazy... I will keep trying, maybe when the car cools down its been in the sun all day and is very hott...

Now if I want to disable the AUTO lights, then all I have to do is the wire cut trick??

[GTJeff]

Is this a new thread or something??

wheres voodoo?

[GTJeff]

OKAY! I did it, pulled the clip out of the sensor >> NOPE!! does not disable DRLs maybe it deactivated the auto lights??? have to wait till it gets dark to see if thats the case, but as for DRLs still got um! darn it...

[morris]

OKAY!

'coz I don't use highs, use fogs, I just disabled the high beams by removing the two 10a fuses ... :gap: I found a cd w/pic when I posted it @ ec "How to disable drl for dummies" :o:

[GTJeff]

OH very nice, for dummies huh....

Well Its dark here now anyways, when I turned the car on, and took the E-brake off just the DRL went on!!!!!!!!!!!!!

and when I turn the lights on and then go to turn them back off, they just stay on? I dunno... whats going on

All I want is a simple way to be able to use my headlights (both high and low beams + foggers) but do-away with the DRL's

1st attempt- removing the sensor, did a little but without the desired results.

Has anyone been able to do this with a 2002 GT let me know. =0)

[Mike21]

cut the yellow/green wire under the ac controls.. it does away with drl's and the auto-on feature. i drive a 2002 gt.

[GTJeff]

Thanks Mike, Ill give it a try, But does it also get rid of the Highbeams?

[Mike21]

nope. still have my highbeams.

[Mike21]

make sure you cut the correct wire...

[GTJeff]

we are talking about the same wire I hope! the green/yellow the one in the installs that is titled -----> Disable DRL & Auto on headlights (one wire method) by clone GTS

[Mike21]

yup.

[GTJeff]

WELP I cut the wire and........IT WORKED! I have no more DRLs and high beams work, I dunno what all the fuss was about, maybe different years are wired where the highbeans and DRLs are combined? like 03+ celicas?

NExt mod i want to tackle is going to be the foggers working independently, this one looks just a bit more complicated. :(

[Mike21]

glad everythign worked out well for you :)

[jotun666]

so when you cut that wire it didnt disable the fogs? all your lights work fine with no problems?

[VoodooTRD]

yes, everything should work fine.

so when you cut that wire it didnt disable the fogs? all your lights work fine with no problems?

[GTJeff]

WHen i cut the wire, Fog lights work, Highbeams work, low beams work, everything works!, but the Daytime running lights are gone

NOW mind you, I have a 2002 GT, other years could be different, but if you have a 2002 then It will likely work out

[Ryousuke]

I just did the 1-wire method & it worked flawlessly.

NOTE: The wire you need to cut is coming from the fusebox..there are 2 plugs that are visible, one is coming out towards the drivers-side & the other is coming out towards you. You want to cut the yellow wire w/green stripe on the plug that is coming out towards you (most towards the passenger side).


For me, it disabled my DRL & auto-on lights. My factory foglights are still working fine w/the switch on the headlight control stick.

[jotun666]

Can you post a picture?
