This article is for those looking for the way to disable your DRL on
2001 & 2002 4Runners without side effects.
2001 & 2002 DRL wiring are identical in color & positions in D8.
DRL module part numbers are the same:
I too found & performed the procedure in the TSB for 2000 vehicles, but it had side effects from the dim intermittent "high beam" indicator light to shorting out the DRL module circuit causing my battery to drain, costing me around $270 to replace the DRL module.
I decided to give it another go to disable the module & did some schematic research with reference to the 2000 TSB's D8 Pin #2 procedure.
I referred to my 2002 Electrical Wiring Diagram (EWD) manual & also went to the service department & obtained copies for the DRL schematic on the 2000 model & compared the two circuits & their respective description of operation section.
Simply put - the DRL circuit operates like a stereo amplifier with a "remote" lead (switched power) to power on the unit.
Even with the vehicle off, headlights, fog lights, parking lights operate independent of DRL.
Per the TSB & schematic for the 2000 4Runner, Pin 2 is the Black/Yellow Stripe wire (switched power).
On the 2001 & 2002 4Runner, Pin 2 is the White/Black Stripe wire, which is the ground wire & needs to remain intact to prevent the side effects & to operate the fog light mod when Pin 16 Green/Black Stripe wire is moved to Pin 2 for ground (See my Fog Light Mod article; 2002 Toyota
4Runner: Fog Light Mod https://www.yotatech.com/showthread.php?t=87997)
2001 & 2002 4Runner Pin 12 =Black/Yellow Stripe wire (switched power via "Gauge" fuse) which powers "on" the DRL circuit.
Hand brake "activates" the circuit. Constant power via pins 2 (White/Black Stripe "Ground") & 3 (Lt Blue/Yellow Stripe "Dome").
Cut the Pin 12 Black/Yellow Stripe wire to disable the DRL "circuit"
operation. A switch can be installed inline between the two separate Black/Yellow Stripe wires for manual DRL operation if desired.
