B2175

DTC B2175

Circuit Description
The steering column module receives ground inputs from contacts inside the tilt/telescoping switch. The steering column module then supplies battery voltage to the tilt motor UP or DOWN circuit, or to the telescope motor IN or OUT circuit, depending on which direction of movement is requested. Both motors are reversible and the circuits are simply reversed to accomplish movement in opposite directions.
