rr diff lock light flash!!!

[moodtoy]

When I push the button of the rr diff lock the light in the dash flash but nothing else happens
What do you think is it?

You have to be in 4-lo for the diff lock to engage. Flashing means that it is not engaged but ready to engage. If you are in 4 lo and it still does not engage. Try moving forward SLOWLY turning back and forth. You may hear a pop when it finally does engage.

Or you can do the blue aka gray wore mod to make the computer think your in 4 low all the time so you can engage the rear locker in any situation. 2 high and 4 high.

Out of curiosity, post-grey/blue wire mod can the locker be engaged while still in two wheel drive if under 5 mph?

Yes it can be locked in ANY situation. 70mph down the highway in 2high. Yes. I would not recommend it tho!

My dash light continues to flash even after i have heard a pop of the locker engaging. I slowly turned side to side on a dirt road and could hear and feel one of the tires skipping. I'm pretty sure the locker is engaging but the light keeps flashing. Is there another way to confirm that the locker is engaged?

If you feel that tire skipping when making a tight turn, then you can be 99% sure it's engaged. On mine, I have to "rock" it back and forth once to get it to disengage. You can definitely hear it disengage.

No button in mine but it started to flash

292,000 miles on my 1996 SR5.
The RR DIFF Lock light on my dash is flashing. It just started a day or two ago.
Does anybody have a clue what is going on? I sure do not.
I did try putting it in four wheel high and low and the green 4x4 light on the dash did not come on. Is it possible the electronic lock is not working for some reason?
Thanks in advance.

Yes the e-locker is not engaging, there's an issue. Try searching on the forums, there's a few suggestions on what to try. The factory e-lockers are known to break and have to be replaced in some situations.

Thank you!

The rear diff lock will only engage in 4LO. If the truck doesn't think it is 4WD (no 4WD light on the dash), it won't engage the rear locker (unless the wiring is modified).

Fix the 4WD problem first, then re-check the rear locker.

Hate to tell you what the problem was. I must have hit the button by mistake and did not realize it. I took it to a field and it engages properly in 4-low. I guess my 4X4 light on the dash is out. I probably can live without the light.
Thanks again

If you have a factory set up. Even if you hit the button by accident. It won’t engage it! That’s why people do the grey wire mod. To engage WHENEVER they desire. The computer won’t engage the locker at high speeds or if it’s not in 4lo.

Op can easily jack up the rear and have someone hit the button and listen if the motor even works at all. If it does, it should easily lock especially when of the ground. If not, take the motor apart. The elocker motor MUST BE PROPERLY CLOCKED in order to work properly. If someone has taken the motor out before out of the housing. You must connect power to it. LOCK IT , lock the rear manually. Install the locker. Then unlock it. That’s how you properly clock and install the elocker motor.
