RECLINING SENSOR

RECLINING SENSOR

Description

INFOID:0000000003759164

• The reclining sensor is installed to the seatback frame.
• The pulse signal is inputted to the driver seat control unit when the reclining is operated.
• The driver seat control unit counts the pulse and calculates the reclining amount of the seat.

Component Function Check

INFOID:0000000003759165

1.

CHECK FUNCTION

1.

Select “RECLN PULSE” in “Data monitor” mode with CONSULT-III.

2.

Check reclining sensor signal under the following conditions.

*1

: The value at the seat position attained when the battery is connected is considered to be 32768.

Is the indication normal?

YES

>> Reclining sensor function is OK.

NO

>> Refer to 

ADP-62, "Diagnosis Procedure"

.
