Transfer Case Control Module – Mopar (68308879ab)

Transfer Case Control Module is an electrically controlled component in the engine or transmission management system. Because the module cross-checks it against other inputs, a fault here often surfaces as a code for a different circuit.

Replace the Case Control Module when a value freezes or drops out intermittently, which usually means an internal fault rather than wiring. Wiggle-testing the harness while watching live data separates the two.

Reference number for the Case Control Module: 68308879ab. It is filed under Transfer Cases, and it is the number that has to match the part coming off the vehicle.

The stock here is genuine MOPAR, and this Case Control Module keeps the original engineering number, which matters once a number has been superseded more than once.
