newbe help not sure my locker is working

I have just bought a 01 TRD 4X4 and i need some help figuring out if my diff lock is working when i drop my truck into low range and engage the diff lock the light on the dash for Diff Lock blinks and the abs light comes on is this normal.

 

Sounds like the actuator is bad had the same problem on my 99 trd....

 

How can i test it to find out if it is bad. If it is where can i buy a new one or can i find a rebuild kit for the one i have.

 

Mine take a minute to lock up aswell...I think its the gears trying to get alligned. When you engage the locker try creeping forward slowly while turning your wheel slightly to the left and right

 

I have tried that and it seems like the locker is engaging. when i disconnect out of 4wd lo and the locker i get 2 clicks with i do not engage the locker and only put it 4wd lo and disconnect it i only get 1 click. is it possible that it is working but the sensor is messed up some way.

 

thanks guys

 

go to a gravel lot engage the e locker and spin some tire. Look at the skid marks. You'll know if it engaged or not. Consider doing the grey wire mod. I love it. It enable you to use the locker in 2 or 4 hi as well.
