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. Ive used the e-locker on this truck enough in the past to know when the locker is engaged and when it isnt 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.
