P1832 & P1876 codes, questions?

P1832 transfer case Differential lockup silenoid circuit failed & P1876 transfer case 2-wheel drive codes silenoid circuit failed

Both of these codes are coming up on my truck and was wondering what I need to look for? I'm guessing what I'm looking for is the silenoid that changes my truck from 2 wheel drive to 4 wheel drive correct? What do I need to look for, shorts, opens? Would this mean that I need to just change this silenoid out? Who's had this problem in the past and what did you have to do about?

Thanks for your help in advance!!

Re: P1832 & P1876 codes, questions?

The manual says check for shorts to ground or opens in the wiring and repair them if found.

You need to check the two outside terminals with your ohmmeter for resistance to ground, and then the resistance of those same two terminals to the other end of the corresponding wires at the GEM connector.

If those are OK, then check the solenoid resistance across the two outside terminals on the plug (which should be between 90 and 115 ohms).

If that's not it then it says replace the GEM. I don't remember ir the 01's had a GEM or not, but if you still have the fuse box under the hood then you do have one.

First truck -- 1929 Model A Ford pickup, restored from ground up. Wish I still had it!
