POWER MIRROR CONTROL SYSTEM (w/ Memory) > Power Retractable Mirrors do not Operate with Power Retract Mirror Switch

for Preparation Click here


SYSTEM DESCRIPTION

The main body ECU (multiplex network body ECU) receives the retractable outer mirror switch signal from the retractable outer mirror switch. The main body ECU then sends the mirror retract/return signal to each outer mirror control ECU assembly via CAN communication. Based on the signal, each outer mirror control ECU assembly retracts or returns the outer rear view mirror assembly.

INSPECTION PROCEDURE

1.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 (Click here)
OK


2.READ VALUE USING INTELLIGENT TESTER (RETRACTABLE OUTER MIRROR SWITCH)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the power switch on (IG).

  1. Turn the intelligent tester on.

Go to step 6
OK


3.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (MIRROR RETRACT FUNCTION)

  1. Enter the following menus: Body / Mirror L or Mirror R / Active Test.

  1. Perform the Active Test according to the display on the intelligent tester.

    Mirror L / Mirror R 
    Tester Display
    		Test Part

    		Diagnostic Note
    Mirror Fold/Return
    		Mirror retract operation
    		Fold / Return
    1. operate with power switch on (IG) and the vehicle stopped.
    2. This test activates the Fold / Return.
    3. This operation can be confirmed by watching the mirror move in the desired direction.
