So i bought a 2001 tacoma trd recently have tried getting the locker to engage, (4 low, fwd, reverse, turning straight the whole works) to no avail, light continuously flashes. Actuator is making no sounds. PO said it worked 6 weeks ago. When the button is pushed and my truck is in 4lo sitting on my driveway in neutral (tranny) and running, i tested the wiring to the actuator by unplugging the 5 wire connector to the actuator here is what i found:
white/black wire: is ground. checked it against one of the license plate lamp bulb ground and it was good to go.
GReen wire (M1): situation as stated above as per the truck, -0.08 v against the white black wire.
Green/red wire (M2): same -0.08v against the white black wire.
green/black: agianst ground, dead
Green/yellow: against ground, dead
Green against Green/red on the old Ohm setting ~70 ohm's
IDK if this helps, what is my next step?
