SYSTEM DESCRIPTION

When the seat memory M1, M2 or M3 switch is pressed, the position control ECU (driver side) memory's driver and passenger seat mirror position signal is sent through the multiplex communication line to the front multiplex network door ECU LH and RH. The front multiplex network door ECU LH and RH then activate the mirror control motors to move the mirrors to the previously recorded positions.

INSPECTION PROCEDURE

1.CHECK OUTER MIRROR CONTROL SWITCH FUNCTION (POWER MIRROR CONTROL FUNCTION)

  1. Check that the mirror surface positions of the outer rear view mirror LH and RH can be moved using the mirror control switch of the integration control and panel assembly.

    OK:
    Mirror surface positions of the outer rear view mirror LH and RH can be moved using the mirror control switch of the integration control and panel assembly.



NG
GO TO PROBLEM SYMPTOMS TABLE
OK


2.CHECK SEAT MEMORY SWITCH FUNCTION (MIRROR MEMORY FUNCTION)

  1. Check that the outer rear view mirror LH and RH positions can be memorized using the seat memory switch.

    OK:
    Outer rear view mirror LH and RH positions can be memorized using seat memory switch.



NG
GO TO FLOWCHART
OK


3.CHECK SEAT MEMORY SWITCH FUNCTION (DRIVER SEAT) (SEAT MEMORY FUNCTION)

  1. Check that the driver side seat can be moved using the seat memory switch.

    OK:
    Driver side seat can be moved using seat memory switch.



NG
GO TO FRONT POWER SEAT CONTROL SYSTEM
OK


4.READ VALUE OF INTELLIGENT TESTER (MIRROR POSITION SENSOR)

  1. Check the Data List for proper functioning of the mirror position sensor.

    Front multiplex network door ECU (LH, RH):

    Item
    		Measurement Item / Range (Display)
    		Normal Condition
    		Diagnostic Note
    Mirror Position Sensor V
    		Vertical mirror position / Min.: 0, Max.: 5 V
    		Within 0 to 5 V
    		-
    Mirror Position Sensor H
    		Horizontal mirror position / Min.: 0, Max.: 5 V
    		Within 0 to 5 V
    		-

    OK:
    Output voltage is as shown in table above.



OK
REPLACE POSITION CONTROL ECU AND SWITCH ASSEMBLY (DRIVER SIDE)
NG


5.INSPECT OUTER REAR VIEW MIRROR ASSEMBLY (MIRROR POSITION SENSOR)

  1. Disconnect the i1 or j1 mirror connector.

  1. Apply battery and dry cell battery voltage to the terminals as shown in the table below.



  1. Measure the voltage while the mirror moves between the fully downward and fully upward positions.
