Transfer Case Switch – Mopar (5107932ab)

Transfer Case Switch 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 Transfer Case Switch 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 Transfer Case Switch: 5107932ab. It is filed under Sensors & Switches, and it is the number that has to match the part coming off the vehicle.

This is MOPAR dealer-sourced stock rather than an equivalent, so the number on the Transfer Case Switch traces straight back to the manufacturer.
