TILT SENSOR

TILT SENSOR

Description

INFOID:0000000003134737

• 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.

Component Function Check

INFOID:0000000003134738

1.

CHECK FUNCTION

1.

Turn ignition switch ON.

2.

Select “TILT SEN” in “Data monitor” mode with CONSULT-III.

3.

Check the tilt sensor signal under the following condition.

Is the indication normal?

YES

>> INSPECTION END

NO

>> Perform diagnosis procedure. Refer to 

ADP-100, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000003134739

1.

CHECK TILT SENSOR SIGNAL

1.

>> Replace automatic drive positioner control unit. Refer to

ADP-210, "Removal and Installation"

.

NO

>> GO TO 2.

2.

CHECK TILT SENSOR CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect automatic drive positioner control unit and tilt & telescopic sensor connector.
