You first want to look to see the status of the code. Is the code current, pending, or permanent? If pending, you will want to clear the code and see if it comes back, same thing with current. If the code is permanent then you would want to start by visually inspecting the wiring harness at the transfer case and the transfer case control module. If there are no visual defects found then you will need to complete a diagnostic procedure to determine if it is the module or the wiring. I would be happy to walk you through this process.

If you have a voltmeter, with the car running check the voltage across the battery posts. It should be around 13.8. If it’s 12 volts or less, even tho your alternator tests out good, it’s not charging the battery and the car will run off the battery until it drains the battery. I’d check the wires coming from your alternator to make sure they have a good connection and not broken and I’d check your fuse box for a blown fuse as well assuming you don’t have a radio or amplifier or something else wires up that stays on all the time. Some alternators are 1 wire and it usually has a wire going directly to the positive battery cable. Also could have a bad fusible link

DTC P1631 Theft Deterrent Fuel Enable Signal Not Correct

The powertrain control module (PCM) controls the fuel injector operation and the starter operation based on a vehicle theft deterrent (VTD) password from the vehicle body control module (BCM). When the ignition is first turned ON, the BCM sends a programmed theft deterrent password to the PCM. The PCM acknowledges the password and responds to the BCM that normal fuel injector and starter operation will continue. If the PCM detects an incorrect password, a theft deterrent system failure, or an attempted vehicle theft, DTC 1631 will set. The engine will not start or crank as long as the condition is present.

Diagnostic Aids
DTC P1631 indicates that the vehicle theft deterrent password that the PCM has learned does not agree with the password received from the VTD system. This condition can occur if the BCM has been replaced and the PCM Password Learn function has not been enabled. If the BCM has been replaced, the password must be relearned.

Did you perform the Diagnostic System Check - Vehicle?
Go to Step 2
Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
Perform the Password Learn Procedure. Refer to Programming Theft Deterrent System Components .
Did you complete the procedure?
System OK

30-Minute Learn Procedure
Turn ON the ignition, with the engine OFF.
Attempt to start the engine, then release the key to ON; the vehicle will not start.
Observe the SECURITY telltale. After approximately 10 minutes, the telltale will turn OFF.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes. The vehicle is now ready to relearn the Passlock™ Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
Important: The vehicle learns the Passlock™ Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
Start the engine. The vehicle has now learned the Passlock™ Sensor Data Code and/or password.
With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.

There is a resistor in the fan circuit to give you different speeds and it burns out. It's down by the fan on most cars.
