< COMPONENT DIAGNOSIS >

TELESCOPIC SENSOR

TELESCOPIC SENSOR

Description

INFOID:0000000001693749

• The telescopic sensor is installed on 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.
