POWER MIRROR CONTROL SYSTEM Power Retractable Mirrors do not Operate with Power Retract Mirror Switch

DESCRIPTION

The multiplex network master switch assembly sends the retractable outer mirror switch signal to the main body ECU (multiplex network body ECU) via LIN communication. The main body ECU (multiplex network body ECU) then sends the mirror retract/return signal to each front multiplex network door ECU via CAN communication. Based on the signal, each front multiplex network door ECU retracts or returns its corresponding outer rear view mirror assembly.

CAUTION / NOTICE / HINT

Note


  • The power mirror control system uses the CAN communication system and LIN communication system. Inspect the communication functions by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication systems are functioning properly.

PROCEDURE


  1. READ VALUE USING GTS (OUTER MIRROR FOLD SW)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Master Switch / Data List.

    5. Read the Data List according to the display on the GTS.


      Body Electrical > Master Switch > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Outer Mirror Fold SW Retractable outer mirror switch signal OFF or ON

      OFF: Retractable outer mirror switch off

  2. PERFORM ACTIVE TEST USING GTS (MIRROR FOLD/RETURN)


    1. Enter the following menus: Body Electrical / Front Left Door or Front Right Door / Active Test.

    2. Perform the Active Test according to the display on the GTS.


      Body Electrical > Front Left Door > Active Test
      Tester Display Measurement Item Control Range Diagnostic Note
      Mirror Fold/Return Mirror retract operation OFF, Return or Fold

      • Operate with the engine switch on (IG) and the vehicle stopped.

      • This test activates the Fold / Return.

      • This operation can be confirmed by watching the mirror move in the desired direction.
