When is the E-Locker Engaged?

The dash light blinks but the axles are locked.

2002 4x4 TRD, no gray wire mod, no ABS.

I have not had a problem until re-gearing recently. The RR Diff Lock indicator on the dash is blinking and will not go solid as it did in the past. I have tried all the normal techniques to get it to engage, yet nothing will make the dash light stop blinking.

The dash indicator is presumably telling me that the locker is not fully engaged. Yet the evidence shows the locker is engaged. I’ve used the e-locker on this truck enough in the past to know when the locker is engaged and when it isn’t just by the way the truck drives. Plus, when I disengage the locker with the button on the dash, I can hear a click (relay noise) from the dash area behind the button as well as the normal disengage sound made by the locker actuator mechanism on the diff.

My concern is that the locking mechanism is in fact only partially engaged, making locker vulnerable to damage though hard use.

Are there any other indicators if the locker is not fully engaged? How are the center differential lock switch (see pic) and differential lock actuator powered? Is there a fuse involved? I looked at both fuse panels but nothing was marked with anything remotely reminiscent of the rear diff lock.

Feedback, thoughts or insights are greatly appreciated.

Have you tried, after engaging it with the button, getting under the truck and manually unengaging it?

Is it just a matter of unplugging the connector on the actuator? I have not tried that while it was engaged. I have verified that connector is properly connected.
I'm throwing this out here, as it happened to us. I'm thinking when you regeared, the fork that sits under the locker motor wasn't pushed all the way over, so although your locker is working properly (I'll take you at your word you know what it feels like) your ECU thinks it isn't.

What we did is press the button and "lock" the diff like normal (the dash will blink otherwise) , get under the truck and take off the locker motor, manually disengage it, put everything back together and turn off the truck.

Then when we started up the truck we did what we normally would to lock (4hi, N, 4lo, lock) and everything worked fine.

I'm going to link you to a thread so you understand the "fork" I am talking about. It is for a 2nd gen, but is the same for you.

Essentially, moving the fork away from the diff unlocks it, and moving it towards the diff locks it. You just need to be sure it is completely over. The posts I oasted shows it being locked.

Once you have that little cover off it's time to remove two electrical connectors from the e-locker motor.

Remove the two electrical connectors by squeezing the tabs while pulling out at the same time:


Remove the two remaining nuts to the e-locker motor and pull the assembly out:


This next step is vital. It is key to removing the 3rd member form the housing. If you forget to do this step there won't be enough room to pull out the 3rd member and it will stay stuck

Using a flat tip screwdriver, move the e-locker engagement fork towards the center of the 3rd member:





Side Note: If you are ever on the trail and your e-locker is not engaging for whatever reason but you really need it to. You can remove the e-locker motor assembly by following the above steps. And you can engage it or even disengage it by hand. it's a quick trail fix that i have done myself.

Does the truck need to be running while I do this? Is it enough for just the ignition switch to be in the ON position?

After manually disengaging the locker and reassembling the actuator, it would have been in 4lo with the dash button already pressed. Did you disengage 4x4, 4lo and the diff lock button before restarting the truck?

Sorry about all the questions, just a little unclear on the sequence you used?

I didn't see a link to the thread you mentioned.

Sorry for not posting the link, the descriptions could be confusing since it's a small part in a large write up on for to remove and reinstall a third member, and I didn't want you to have to dig through it.

My sequence of events is a little unclear since we were on a trail when we did it.. Whether or not everything HAS to be a certain way is uncertain, since we just came upon the issue, did what we did and it worked.

We were on a trail and locked the diff.. Heard and felt it lock, but the dash just kept blinking. Thinking, that's odd, we went under and removed the motor to visually see that, yes, the fork is pushed all the way towards the diff, it is in fact locked. So we moved the fork the opposite way to unlock it, then put the truck back in 2wd like normal, then turned the truck off.

Then we started the truck back up, went into the normal motions to engage the locker (still needed it for the trail lol).. And the dash finally showed the it was locking (light stayed on)
