Motorcraft Differential Control Module – Ford (tm326)

Motorcraft Differential 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 Differential 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 Differential Control Module: tm326. It is filed under Differentials, and it is the number that has to match the part coming off the vehicle.
