B2118 TILT SENSOR
Description
INFOID:0000000000960630
• 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.

B2119 TELESCOPIC SENSOR
Description
INFOID:0000000000960633
• 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.
