After performing a "Read", it displays the C1417 code.
It just won't "Clear" the code, even with multiple attempts in succession (Ignition "ON", engine not running).
If that's the code your getting then you have a REAL fault that's unrelated to the N23 . That's what happens when you have a hard fault condition , you can try clearing it till your blue in the face but it's still there . also that code has nothing to do with your transfer case , the problem is in the differential solenoid or electrical associated with it .
from the service manual :
C1417–FRONT DIFFERENTIAL CONTROL CIRCUIT LOW
For a complete wiring diagram Refer to Section 8W.
˛ When Monitored:
The Solenoid is active, no solenoid supply circuit DTCs are present and battery voltage is normal.
˛ Set Condition:
The FDCM detects the Front Differential Solenoid Control is shorted low
FRONT DIFFERENTIAL SOLENOID
(T306) FRONT DIFFERENTIAL SOLENOID CONTROL CIRCUIT SHORTED TO GROUND
(T306) FRONT DIFFERENTIAL SOLENOID CONTROL CIRCUIT OPEN
(T301) SWITCHED BATTERY SOLENIOD SUPPLY OPEN/SHORTED TO GROUND
