SYSTEM DESCRIPTION [04/2013 - ]
- POWER MIRROR CONTROL SYSTEM (w/o Memory) DESCRIPTION This system has the following functions: electrical remote control mirror function, mirror heater function and automatic glare-resistant EC mirror function*. *: w/ EC Mirror
- FUNCTION OF MAIN COMPONENT Component Function Outer rear view mirror assembly Vertical mirror motor Moves the mirror surface vertically in accordance with the multiplex network master switch assembly operation (up or down). Horizontal mirror motor Moves the mirror surface horizontally in accordance with the multiplex network master switch assembly operation (right or left). Mirror heater When the mirror heater switch (rear window defogger switch) on the air conditioning control assembly is operated, the air conditioning amplifier assembly detects the switch operation via LIN communication. The air conditioning amplifier assembly operates the semiconductor pwr integration ECU and mirror heaters in accordance with the switch operation. EC mirror cell* Varies the reflection rate of the mirror through function of EC elements. Multiplex network master switch assembly Mirror select switch Consists of individual R and L switches. One must be on to operate the multiplex network master switch assembly. 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. *: w/ EC Mirror
- SYSTEM OPERATION The power mirror control system (w/o Memory) has the following features: Function Outline Electrical remote control mirror function When the outer mirror switch on the multiplex network master 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. 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. The outside temperature is -3°C (27°F) or lower. The vehicle speed is 45 km/h (28 mph) or higher. Automatic glare-resistant EC mirror function* Reduces glare/reflection in the mirror during nighttime driving for safer driving conditions. Glare/reflection from vehicle headlights behind could blind the driver and cause dangerous driving conditions. *: w/ EC Mirror
OPERATION CHECK [04/2013 - ]
- CHECK ELECTRICAL REMOTE CONTROL MIRROR FUNCTION Turn the engine switch on (IG). With the mirror select switch L switch on, check that the outer rear view mirror assembly LH surface moves up, down, left and right normally. With the mirror select switch R switch on, check that the outer rear view mirror assembly RH surface moves up, down, left and right normally.
- CHECK MIRROR HEATER FUNCTION Turn the engine switch on (IG). Check that pressing the mirror heater switch (rear window defogger switch) illuminates the indicator and warms the mirror surfaces. Check that after approximately 15 minutes, the indicator light turns off and the mirror heaters deactivate. HINT: There is a timer extension function which can operate the mirror heater system for up to an additional 45 minutes.
- CHECK AUTOMATIC GLARE-RESISTANT EC MIRROR FUNCTION (w/ EC Mirror) Check that the automatic glare-resistant EC mirror function of the outer rear view mirror assemblies operate when the automatic glare-resistant function of the inner rear view mirror assembly is operating.
DESCRIPTION
When the mirror heater switch (rear window defogger switch) on the air conditioning control assembly is pressed, the operation signal is sent to the air conditioning amplifier assembly via LIN communication. When the air conditioning amplifier assembly receives the signal, it turns on a relay in the semiconductor pwr integration ECU to operate the mirror heaters.
