Locker Indicator Problem

I am having a problem with my locker indicator on the dash. I have put my truck up on 4 jack stands put it in 4wd low pressed the diff lock button and climbed under it. The locker engaged but the diff lock light on the dash flashes and the abs light comes on. I am not sure to where to start my diagnosis.

 

Are you 100% it engaged? Try going on some dirt and engaging the locker while going under like 5 miles an hour and wiggle the steering wheel around a bit to line up the gears or something like that. Sometimes it can be a pain if it's not used often.

 

I have tried that and it seems to be fully engaged with makes me think it is an electrical problem. When i climbed under it i could hear the actuator engage as well.

 

Did you do a sharp turn in the dirt and look at the tracks? It should have pulled up some dirt on the inside tire if it was engaged.

Atleast on the second gens it blinks when it's not fully engaged.

 

Unless the acuator is bad, & you are sure it's in 4-low sounds like it's not engaged, also it won't engage the rear locker unless its in 4 low (there is a mod to change this on this site)My 2000 TRD did the same thing first time I was figuring shit out (my first locking diff, my first IFS 4x) Usually if you engage it & either slowly pull forward while turning right (or left ?)or you can pull forward a few feet & then reverse a few feet, it takes a few seconds of this to allow the rear diff gears to mesh, trust me , you'll know when it does engage.... hope this helps, good luck ...

 

Thanks for the help i am going to complete the mod to change the locker to engage in 2 wheel drive and i will double check it in the dirt.

 

Have you ever tried the diff lock other then on the jack stands?

The ABS light is supposed to come on. When the locker engages your abs is disabled. Even with the locker mod this is true.

As for engaging sometimes it takes a bit of time. Come to a stop, engage the locker, the abs light should come on solid and the diff lock light will flash. Slowly take off and turn back and forth (the back wheels a
have to spin at different rates of speed to get it to engage.)

Hope all works out for yeh.

 

As already mentioned, the ABS light coming on is normal.

If you confirm the locker is engaging, it might be that the locker detection switch is dead or disconnected. If the switch is 'off' during the lock motor operation, the dash indicator light is supposed to flash.

The light is also supposed to flash if you attempt to engage the locker at a speed higher than around 5 mph.

 

Where is the locker detection switch located. I will take a look to make sure it's not disconnected. Also i have seen some people online taking apart the actuator and clearing it out inside and re greasing everything. Is this a common practice. Thanks

 

I have just took the truck around back of my work in the dirt and i sure the locker is engaged both wheel turn together but that dag gone light just keeps flashing. Thanks for the pages out of the manual i am going to mess around with the truck some more tonight when i get off work.
