my service 4x4 light came on in my 2003 dodge 1500, 5.7L hemi. when i went to look at the codes with the matco scanner it would not even connect to the transfer case! luckily my friend who is a mechanic was kind enuff to scan it for me. i also had a loss of torque management code stored in the transmission? anyone know what that would indicate.

also the lights on the **** to go from 2 wheel drive to 4 hi and 4 lo arent working.

can anyone tell me if i need a new module, or would that warning come up for any other reason?

TIA
