Hello friends,
Great forum. I'm impressed. I read the threads explaining how 4WD works. Did a bunch of troubleshooting. I have good vacuum at switch on transfer case. Actuator and cable are good. No leak between switch and actuator.
I grounded pin 13 on datalink port, and found a stored trouble code. Does anyone know what code 2 (or Two flashes means)?
BTW in case you are wondering I have the same symptoms as many other posts. 4HI and 4Lo blink and go back to 2HI in Neutral only and fully stopped. Nothing happens if vehicle is moving or in any other gear.
Thank you all in advance for your help and for a great forum.
Gab.

Read through this thread in the DIY section: OBD2 Non-Automatic Transfer Case Diagnostics

All your questions should be answered there.

Kyle,
Thanx a million for your response. Very helpful. I replaced shift motor with a remanufactured unit from Cardone $152.99. I now can go into 4LO if stopped in Neutral. Easily goes back to 2HI when selected. Cannot go into 4HI under any condition. Now I get a code 1 plus the code 2 I got before. Instructions say something about removing codes with scanner. I did disconnetc battery when replacing the part. Help! Can the culprit be the part i replaced? is it bad possibly? Thanx.
Gabriel.
