System Description [08/2015 - ]

POWER MIRROR CONTROL SYSTEM DESCRIPTION
1. This system has the following functions: electric retract function*1, automatic glare-resistant electrochromic (EC) mirror function*2, reverse shift-linked function, electrical remote control function, memory function and mirror heater function.
  1. *1: w/ Retract Mirror
  2. *2: w/ EC Mirror

FUNCTION OF MAIN COMPONENT

Component	Function
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.
Power retract mirror motor*1	Receives a signal from the outer mirror control ECU assembly, and retracts and returns the outer rear view mirrors.
Mirror heater	Receives a signal from the outer mirror control ECU assembly and operates mirror heater
EC mirror cell*2	Varies reflection rate of the mirror through function of EC elements.
Mirror retract switch*1	Retracts and returns the outer rear view mirrors. Mirror retract and return signals are sent to each outer mirror control ECU assemblies from the main body ECU (multiplex network body ECU).
Mirror select switch	Consists of R and L switches. One must be chosen to operate the outer mirror switch assembly.
Mirror adjust switch	Mirror R and L signals are sent to each outer mirror control ECU assemblies from the mirror select switch. After selecting the R or L switch, the right, left, up and down control switches can be operated to change the angle of the mirror.
Mirror position sensor	Detects the mirror surface position. This data is detected by the outer mirror control ECU assembly.
Seat memory switch	When the seat memory M1 or M2 switch are pressed while the SET switch is being pressed, or M1 or M2 switch is pressed within 3 seconds after the SET switch being pressed, a signal is input to the outer mirror control ECU assembly LH, which records the mirror surface position. When the seat memory switch is pressed, a signal is input to the outer mirror control ECU assembly LH and sent to main body ECU (multiplex network body ECU), which changes the mirror surface position to the recorded position.
Outer mirror control ECU assembly	Operates each mirror motor based on signals from the outer mirror retract switch*1, mirror select switch and mirror adjust switch. Based on information from the mirror position sensor, 2 different mirror surface positions can be stored. By operating a seat memory switch, the mirror surface moves to the stored position.

*1: w/ Retract Mirror
*2: w/ EC Mirror

SYSTEM OPERATION

The remote control mirror has the following features.

Function	Outline
Power retract mirror function*1	Retracts and returns the outer rear view mirrors when the outer mirror retract switch is pressed.
Reverse shift-linked function of mirrors	Directs the mirror surface downward to improve visibility when driving in reverse and all the conditions below are met: The engine switch is on (IG). Shift lever is moved to R. The mirror select switch is in the R or L position.
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. Setting the mirror select switch to the R position operates the right mirror, and setting it to the L position operates the left mirror.
Memory and reactivation function	When the SET switch and seat memory M1 or M2 switch are pressed simultaneously, the mirror position is recorded. Then, when the seat memory M1 or M2 switch is pressed, the mirror position changes according to memory.
Automatic glare-resistant EC mirror function*2	Reduces glare/reflection in the mirror during nighttime driving for safe driving conditions. Glare/reflection from vehicle headlights behind could blind driver and cause dangerous driving conditions.
Mirror heater function	Automatically turns on mirror heater when the mirror heater switch is turned on. The rear window defogger and mirror heaters automatically turn off after 15 min. For vehicles with an air conditioning system, there is a timer extension function which can operate the mirror heater function for up to an additional 255 minutes.
