B2118 TILT SENSOR

B2118 TILT SENSOR

Description

INFOID:0000000003134655

• The tilt sensor is installed to the steering column assembly.
• The resistance of tilt sensor is changed according to the up/down position of steering column.
• The terminal voltage of automatic drive positioner control unit will be changed according to a change of tilt

sensor resistance. Automatic drive positioner control unit calculates the tilt position from the voltage.

Description

INFOID:0000000003134658

• The telescopic sensor is installed to the steering column assembly.
• The resistance of telescopic sensor is changed according to the forward/backward position of steering col-

umn.

• The terminal voltage of automatic drive positioner control unit will be changed according to a change of tele-

scopic sensor resistance. Automatic drive positioner control unit calculates the telescopic position from the
voltage.
