Toyota Yaris: Power Mirror Control System / System Description
SYSTEM DESCRIPTION
POWER MIRROR CONTROL SYSTEM DESCRIPTION
(a) This system has the following functions: electrical remote control mirror function, power retract mirror function, auto power retract mirror function and mirror heater function.
FUNCTION OF MAIN COMPONENT
| Component | Function | |
|---|---|---|
| Outer rear view mirror assembly | Vertical mirror motor | Receives signals from the outer mirror switch assembly and adjusts the mirror surface position vertically. |
| Horizontal mirror motor | Receives signals from the outer mirror switch assembly and adjusts the mirror surface position horizontally. | |
| Power retract mirror motor | Receives a signal from outer mirror switch assembly, and retracts and returns the outer rear view mirror assemblies. | |
| 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 DEF relay and mirror heaters in accordance with the switch operation. | |
| Outer mirror switch assembly | Mirror select and surface adjust switch |
|
| Auto retractable mirror switch | Built into the outer mirror switch assembly and sends the auto retractable outer mirror switch signal to the main body ECU (multiplex network body ECU). | |
SYSTEM OPERATION
(a) The power mirror control system 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. Turning the mirror select and surface adjust switch to the R position operates the right side mirror, and turning the mirror select and surface adjust switch to the L position operates the left side mirror. |
| Power retract mirror function | Retracts and returns the outer rear view mirror assemblies when the retractable outer mirror switch is operated. |
| Auto power retract mirror function | Retracts and returns each outer rear view mirror assembly together with the following operations while the auto retractable outer mirror switch is on.
|
| 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. |
