System Description [10/2022 - 11/2023]

  1. POWER MIRROR CONTROL SYSTEM (w/ Memory) DESCRIPTION 
    1. This system has the following functions: electrical remote control mirror function, power retract mirror function, auto power retract mirror function*, memory and reactivation function and mirror heater function.
      1. *: w/ Automatic Retractable Mirror
  2. FUNCTION OF MAIN COMPONENT 
    Component Function
    Outer rear view mirror assembly Vertical mirror motor Receives a signal from the outer mirror control ECU assembly and adjusts the mirror surface position vertically.
    Horizontal mirror motor Receives a signal from the outer mirror control ECU assembly and adjusts the mirror surface position horizontally.
    Mirror position sensor Detects the mirror surface position. This information is sent to the outer mirror control ECU assembly.
    Mirror heater Receives a signal from the outer mirror control ECU assembly and operates the mirror heaters.
    Outer mirror switch assembly Mirror select switch Consists of individual R and L switches. One must be selected to operate the mirror adjust switch.
    Mirror adjust switch Mirror R and L signals are sent to each outer mirror control ECU assembly from the mirror select switch.
    After turning the mirror select switch R or L switch, on the right, left, up and down control switches can be operated to change the angle of the mirror surface.
    Retractable outer mirror switch
    • Retracts and returns the outer rear view mirror assemblies. Mirror retract and return signals are sent to each outer mirror control ECU assembly from the main body ECU (multiplex network body ECU).
    • Sends the mirror auto retract signal to the main body ECU (multiplex network body ECU).
    Seat memory switch When the seat memory M1 or M2 switch is pressed while the SET switch is being pressed, or the M1 or M2 switch is pressed within 3 seconds of the SET switch being pressed, a signal is sent to the outer mirror control ECU assembly (driver door), which records the mirror surface position.
    When the seat memory switch is pressed, a signal is sent to the outer mirror control ECU assembly (driver door) and sent to the main body ECU (multiplex network body ECU), which changes the mirror surface position to the memorized position.
    Outer mirror control ECU assembly Operates each mirror motor based on signals from the mirror select switch and mirror adjust switch.
    Based on information from the mirror position sensors, 2 different mirror surface positions can be memorized. By operating a seat memory switch, the mirror surface moves to the memorized position.
  3. SYSTEM OPERATION 
    1. The power mirror control system (w/ Memory) has the following features.
      Function Outline
      Electrical remote control mirror function When the outer mirror switch assembly is operated, this function moves the mirror surface vertically or horizontally to enable the driver to attain an optimal mirror angle. Pressing the mirror select switch R switch operates the right side mirror, and pressing the mirror select switch L switch operates the left side mirror.
      Memory and reactivation function Stores the adjusted mirror surface position in the outer mirror control ECU assembly.
      Power retract mirror function Retracts and returns the outer rear view mirror assemblies when the retractable outer mirror switch is pressed.
      Auto power retract mirror function*1 Retracts and returns each outer rear view mirror assembly together with the following operations while the retractable outer mirror switch is in auto retract position.
      • Manual lock/unlock
      • Key-linked lock/unlock
      • Wireless door lock/unlock
      • Wireless 60 seconds auto lock
      • Entry lock/unlock
      • Smart 60 seconds auto lock
      Reverse shift-linked function Directs the mirror surface downward to improve visibility when driving in reverse and all of the following conditions are met:
      • The ignition switch is ON.
      • Shift lever is moved to R.
      • The mirror select switch R or L switch is on.
      Reverse shift-linked mirror position memorization function Memorizes the mirror surface position when the outer mirror switch is operated while the reverse shift-linked function is operating (can be enabled or disabled using the customize function).
      Mirror heater function Turns on the mirror heaters when the rear window defogger is turned on. The rear window defogger and mirror heaters automatically turn off 15 minutes after the rear window defogger and mirror heaters were activated.

      The rear window defogger and mirror heaters continue to operate up to an additional 45 minutes if the following conditions are met.*2

      • The outside temperature is -3°C (27°F) or lower.
      • The vehicle speed is 45 km/h (28 mph) or more.
      • Power generated by the generator assembly installed to the vehicle is stable.
      1. *1: for Gasoline Model
      2. *2: w/ Automatic Retractable Mirror
