LIFTING SENSOR (REAR)

LIFTING SENSOR (REAR)

Description

INFOID:0000000000960714

• The lifting sensor (rear) is installed to the seat slide cushion frame. 
• The pulse signal is inputted to the driver seat control unit when the lifting (rear) is operated.
• The driver seat control unit counts the pulse and calculates the lifting (rear) amount of the seat. 

Component Function Check

INFOID:0000000000960715

1.

CHECK FUNCTION

1.

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

2.

Check lifting sensor (rear) 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

>> INSPECTION END

NO

>> Perform diagnosis procedure. Refer to 

ADP-108, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000000960716
