POWER MIRROR CONTROL SYSTEM (w/ Memory) Driver Side Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

When the mirror adjust switch is operated, the main body ECU (multiplex network body ECU) detects the switch operation and sends the mirror adjust switch signal to the outer mirror control ECU assembly (driver side) via CAN communication. On receiving the signal, the outer mirror control ECU assembly (driver side) operates the vertical and horizontal mirror motors, which are built into the outer mirror actuator assembly (driver side), to adjust the mirror surface position.

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

   
   

   1. Enter the following menus: Body / Mirror L*1 or Mirror R*2 / Active Test.

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

      
      

      • *1: for LHD

      • *2: for RHD

      Mirror L / Mirror R

      Tester Display	Test Part	Control Range	Diagnostic Note
      Mirror Up/Down	Mirror vertical operation	Up / Down	Operate with power switch on (IG) and the vehicle stopped. This test tilts the mirror up or down. This operation can be confirmed by watching the mirror move in the desired direction.
      Mirror Right/Left	Mirror horizontal operation	Right / Left	Operate with power switch on (IG) and the vehicle stopped. This test tilts the mirror right or left This operation can be confirmed by watching the mirror move in the desired direction.

      OK
      Power mirror operation is normal.
