Checked my sister 6.0L with my AE and got to transfer case codes. P1876 (transfer case 2 wheel drive circuit failure) & P1382 (transfer case differential lock-up solenoid circuit failure) codes. She has an 2006 F-350 4x4 CC Lariat 6.0L.

What should I check ??

Thanks in advance!

Here is something to investigate

4 Wheel Drive Not Working - TheDieselGarage.com

 

Thanks Mark.

Update: Checked VL's, relays, plugs/connectors and TC. Didn't see anything unusual. Cleared codes and ran for a day, including 4x4 (High and Low). Everything functioned properly including lights. Checked for codes and had none.

Not sure what caused the ghost codes, but something interrupted the TC circuit. Will keep this issue updated so we can get some searchable data on these codes.

Thanks again......
