POWER MIRROR CONTROL SYSTEM (w/ Memory) > AUTO Power Retract Mirrors do not operate

for Preparation Click here


DESCRIPTION

The retractable outer mirror switch sends a voltage signal to the main body ECU (multiplex network body ECU) in accordance with switch operation (switch input signal). The main body ECU (multiplex network body ECU) uses CAN communication to send this information to the outer mirror control ECU assembly, which then controls the mirrors.
When the outer mirror control ECU assembly receives a door lock output signal from the main body ECU (multiplex network body ECU) while the retractable outer mirror switch is in the AUTO position, the outer mirror control ECU assembly operates the retract motors built into the outer rear view mirror assemblies to retract or return the mirrors.

INSPECTION PROCEDURE

1.CHECK POWER RETRACT MIRROR FUNCTION

  1. Check power retract mirror function (Click here).

    OK:
    Power retract mirror function is normal.



NG
GO TO OTHER FLOW CHART (Retract Mirror do not Operate with Retract Switch) (Click here)
OK


2.CHECK CAN COMMUNICATION SYSTEM

  1. Use the intelligent tester to check if the CAN communication system is functioning normally (Click here).

    OK:
    CAN communication DTC is not output.



NG
GO TO CAN COMMUNICATION SYSTEM (DIAGNOSTIC TROUBLE CODE CHART) (Click here)
OK


3.CHECK WIRELESS DOOR LOCK CONTROL SYSTEM

  1. Check the wireless door lock control system (Click here).

    OK:
    Wireless door lock control system is normal.



NG
GO TO WIRELESS DOOR LOCK CONTROL SYSTEM (PROBLEM SYMPTOMS TABLE) (Click here)
OK


4.CHECK ENTRY AND START SYSTEM (ENTRY FUNCTION)

  1. Check the entry and start system (entry function) (Click here).

    OK:
    Entry and start system (entry function) is normal.



NG
GO TO ENTRY AND START SYSTEM (PROBLEM SYMPTOMS TABLE) (Click here)
OK


5.READ VALUE USING INTELLIGENT TESTER

  1. Connect the intelligent tester to the DLC3.

  1. Turn the power switch on (IG).

  1. Turn the intelligent tester on.

  1. Enter the following menus: Body / Main Body / Data List.

  1. Read the Data List according to the display on the intelligent tester.

    Main Body 
    Tester Display
    		Measurement Item/Range
    		Normal Condition
    		Diagnostic Note
    Auto Mirror SW
    		Retractable outer mirror switch signal / ON or OFF
    		ON: Retractable outer mirror switch in AUTO position
    OFF: Retractable outer mirror switch in except AUTO position
    		-

    OK:
    On the intelligent tester screen, ON or OFF is displayed for each item according to the table above.



NG
Go to step 7
OK


6.REPLACE OUTER MIRROR CONTROL ECU ASSEMBLY

  1. Replace the outer mirror control ECU assembly (Click here).



NG
REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) (Click here)
OK

END (OUTER MIRROR CONTROL ECU ASSEMBLY WAS DEFECTIVE) 

7.INSPECT RETRACTABLE OUTER MIRROR SWITCH


    B245707E01

  1. Remove the retractable outer mirror switch (Click here).

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Switch Condition
    		Specified Condition
    H137-8 (MF) - H137-3 (E)
    		AUTO position
    		Below 1 Ω
    H137-8 (MF) - H137-3 (E)
    		Except AUTO position
    		10 kΩ or higher

NG
REPLACE RETRACTABLE OUTER MIRROR SWITCH (Click here)
OK


8.CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - RETRACTABLE OUTER MIRROR SWITCH)

  1. Disconnect the H17 connector from the main body ECU (multiplex network body ECU).

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:

    Tester Connection
    		Condition
    		Specified Condition
    H137-8 (MF) - H17-27 (AMR)
    		Always
    		Below 1 Ω
    H137-8 (MF) - Body ground
    		Always
    		10 kΩ or higher



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (MAIN BODY ECU - RETRACTABLE OUTER MIRROR SWITCH)
OK
