P1874 Fault Code: Understanding The Transmission Component Slippage
The P1874 fault code refers to a power circuit failure in the Transfer Case Hall Effect Sensor.
This sensor is responsible for communicating the operator’s choice to the Transfer Case Control Module (TCCM). When the TCCM commands the gearmotor encoder assembly to 4H mode, the transfer case shift fork engages 4H mode and activates the dual-cone synchronizers to synchronize the front and rear drivelines.
Additionally, the TCCM activates the hublock vacuum solenoid, which engages the Constant Vacuum Hublock (CVH) at each front wheel. If the vehicle is not responding as intended, it is important to systematically check the inputs and outputs of the TCCM, transfer case components, CVH components, and axle shafts.
It is also crucial to inspect all circuits for any opens or shorts to power or ground.
By identifying and addressing any issues in these areas, the power circuit failure causing the P1874 fault code can be resolved, ensuring proper functioning of the transfer case and driveline.
