Typically one cannot disable a drl on the 2003 Honda Accord because it is a required safety feature. To disable the drl you would have to take it to any Honda service center and have them disable the drl for you. They would have to disconnect the required attachments to successfully disable the drl without compromising the rest of the mechanisms.
take the relay out
I found this web site on DRL, check it out. http://www.lightsout.org/disable.html
push the overide swithch 2 times
Simple: Remove fuse #15. It is labeled DRL/FOG. If you have fog lights you will lose those too.
The fuse to disable the DRL system is located in the passenger side fuse box near the glove box.
If you lift your ebrake handle one notch, it will not engage the brake, but it will turn off your drl's. Or you could always pull the fuse.. :)
drl main relay location at left side of the dash panel , you can not disable drl from relay No. 5 , I will tell you how to disable drl Toyota echo . first you pull out toward you the dash panel cover , it will come out easy , you will find at left side of panel two small boxes fixed on a bar , first one is red door lock/ unlock relay , you have to loose from bar to reach the second one which is black , that black one is drl main relay , only you have to take out harrness and no drl any more but in this case your parking brake lights will not go on if you use park brake , another way you can cut the red wire in harness pin 12 and return back harness to relay , your parking brake light will be working only you disable drl , hope you understand ?
Under the carpet where the front seat passenger puts their feet.
Remove no. 11 circuit breaker from fuse box under hood!!
Find and disable the DRL module.
To stop running the DRL daytime running lights in the 2005 Toyota Echo the headlight relay needs to be modified. The DRL module on the relay needs to be cut and relay inserted into the harness.
