Differential Control Module – GM (84731844)

Differential Control Module is part of the circuit that reports engine or transmission behaviour back to the control module. It is read continuously, and a value that drifts out of range sets a fault code long before the driver notices anything.

Replace the Differential Control Module when the code returns after clearing, when the live data reading is out of range at operating temperature, or when the housing shows heat damage. Check the ground and the connector pins first.

The Differential Control Module in this listing carries part number 84731844 and sits in the Differentials category. The number stamped on the original part is the only reliable cross-reference.

Genuine GM supplied for this Differential Control Module, with the engineering number unchanged from the factory reference stamped on the original.
