Your resume looks quite IMPRESSIVE... and yes, you are more than qualified for our new position. All you'll be responsible for are to pick up any pencil or pens that may drop on the floor, and to replace any overhead lights that might blow out. Attire is not business but casual beach wear.

Can anyone confirm that this info is correct. I am in the process of getting ready to install a LED DRL kit and I would like to disable the factory DRL's. I am being told that this is NOT an option via Toyota Techstream. I would ideally like to turn these off and keep high-beam functionality. One Lexus independent shop mentioned that these lights are in series and receive 6v's hence why they are dim.

My local dealership told me this is not an option. Any more insight?

Edit:

There is no fuse labeled DRL. There has to be a relay in there somewhere. Fuse 86 when pulled kills the high beams totally. Hmmm. There must be a way.

I'm not sure if the DRLs trip the "bulb out" message but if so, take the bulbs out and put a resistor that matches the bulb resistance between the two contacts on the socket. If not, just take the bulbs out.

Depends on how old the dealers techstream is but ours does have the Lexus personalization settings present in our units. There isn't any difference in the techstreams between Toyota or Lexus dealers.

Thank you. This is good news. I went ahead and ordered this earlier today. I know this is not the oem interface cable but for the money it's worth a try. Seller has good ratings so I wanted to give it a try. Comes with version 9.00.025

Pulling fuse 86 does the same thing and does not cause any problems but I want to preserve high-beam functionality.

Pulling the fuse kills power to the circuit. A resistor in place of a bulb tricks the circuit into thinking a bulb is there when it really isn't. You still retain high beams but no DRLs

Sorry, I don't get it. Please explain why anyone would chose to eliminate a very effective safety feature ?

I'm adding a LED DRL kit. I don't need both. I'm also not a fan of the dated yellow look of the stock high-beam at 6v style of DRLs.

I see what you mean. That probably would be my next option if I can't get the Techstream to work. I like the idea of all the other options I can set as well as odb2 code reading.

The dealer disabled my DRL for me and I still have my high beam option. I had them make a series of adjustments like also disabling the steering column that automatically moves everytime the door is opened.

I think they charged me something like 3/4 hr in labor (around $85) but I could make as many adjustments for the same price.

Attached is a list of all the different options they can program.

I will say most Lexus service advisers are clueless and I basically had to go to a different adviser to get it done with this list printed out.

Thank you Brad. You don't have the PDF for 04-06 models do you?

you should post some photos once you get your LED DRL's in. Ive been thinking about doing this for a while, but i didn't know you had to get a whole new kit to do so. On my SC you could just pull out the bulb and slip a LED in and it works fine and looks great.

I will for sure. I went with the Phillips DRL kit. It seems to be the most professional I could find.

I'm envisioning something like this. Could not find a LS430 pic.
