Have Toyota Questions? Ask a Mechanic for Answers ASAP
im cam, a licenced diagnostic tech.
there are different drl relays.
the main drl relay which is activated by the BCM is the DRL 2 in the engine juction box.
The green and red wire going to that relay is the main control from bcm. this is the one that would need to be cut .
I did notice in the wiring diagram that there is a DRL fuse in the engine fuse compartment.
I would recommend locating this fuse and unplugging this first before cutting any wires.
i have included a wiring diagram for you
let me know how it works out,
how did your repair go?
the bcm is the body control module
i would definatley try removing any of the drl relays for sure, mainly the drl2 relay. I probably would have tried that for sure before wire hunting under the fuse box
it only takes a minute and maybe get lucky lol
let me know if you run into issues
