CDL Problems Need Wiring Diagram

x2 Glad it is working, I have been following this thread.

I had a similar problem with my Explorer where the lowrange actuator position gear's contacts get dirt and the actuator seizes itself. It's not at all a fun rebuild, but we always found that a thorough cleaning made the lowrange shift happen much more quickly.

Glad you got 'er fixed

Glad it worked! As clean as it looked it's hard to believe that it was bound up!

I was really suprised myself, I have never seen something like that happen, I think I will make sure I shift into low 4 at least once a month to keep it from seizing again.

Again, thanks for all of the help, now I just need to figure out my PO401 so I can start working on the fun stuff like a lift, tires and finding front and rear stock e-lockers to complete the set.

Thanks

Well, I jumped pins 4,5 and 6 with a couple of paperclips(which worked perfect) then checked for voltage on pins 2 and 3. I found that I am getting 11.6 volts to pins 2 and 3 which means that power must be getting to the actuator. I guess that means it must be a problem with the actuator. I will try and get the FSM from techinfo.toyota.com, hopefully they fixed their site.

Is is possible to remove the actuator without dropping the t-case?

I just perfomed this same test and I think I've confirmed that my actuator motor is bad, or in need of repair. When I jumped the 4, 5, and 6 pins coming from the relay to the actuator, pins 2 and 3 read 12V when the transfer case was shifted into Hi, However it showed 0 V when it was shifted into 4Lo....Do I need to jump the 4lo indicator as well to get this to work or could there be another problem that is causing the relay not to send power to the actuator motor when in 4Lo?
