TILT SENSOR

TILT SENSOR

Description

INFOID:0000000010051785

• The tilt sensor is installed to the steering column assembly. 

• The pulse signal is input to the driver seat control unit when the tilt is operated.

• The driver seat control unit counts the pulse and calculates the tilt amount of the steering column. 

Component Function Check

INFOID:0000000010051786

1.

CHECK FUNCTION

1. Select “TILT PULSE” in “DATA MONITOR” mode with CONSULT.

2. Check tilt sensor signal under the following conditions.

Is the indication normal?

YES

>> Inspection End.

NO

>> Perform diagnosis procedure. Refer to 

ADP-86, "Diagnosis Procedure"

.
