DTC Descriptor

DTC C0374 54

- General System Performance Temperature High

Diagnostic Fault Information

Circuit/System Description

The general system performance DTC sets based on a thermal module within the transfer case shift control module (TCCM) software. The

components included in this thermal model are the motor driver within the TCCM, the shift motor, and the clutch inside the transfer case.

This fault occurs when one of the three components included in the thermal model surpass the upper limits of this model indicating possible damage

to the transfer case or other driveline components. This DTC detects an over temperature condition base on a thermal model.
