Toyota Venza: System Description



(a) This system has the following functions: power retract mirror function*, reverse shift-linked function, electrical remote control function, memory function and mirror heater function.

  • *: w/ Retract Mirror




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.

Power retract mirror motor*

Receives a signal from the outer mirror control ECU assembly, and retracts and returns the outer rear view mirror assemblies.

Mirror position sensor

Detects the mirror surface position. This data is detected by the outer mirror control ECU assembly.

Mirror heater

When the mirror heater switch on the air conditioning panel is operated, the air conditioning amplifier detects the switch operation via LIN communication. The air conditioning amplifier operates the engine room junction block assembly and mirror heater in accordance with the switch operation.

Outer mirror switch assembly

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 assembly 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.

Retractable outer mirror switch*

Retracts and returns the outer rear view mirror assemblies.

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 main body ECU (driver side junction block assembly), 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 stored. By operating a seat memory switch, the mirror surface moves to the stored position.

(a) The remote control mirrors have the following features.



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

Stores the adjusted mirror 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.

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 ignition switch ON.
  • Shift lever is moved to R.
  • The mirror select switch is in the R or L position.

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 after 15 min after the mirror heater was activated, the mirror heater continues to operate up to approximately 45 minutes. If the following conditions are not met, the rear window defogger stops operating immediately.

  • The outside temperature is 0°C (32°F) or below.
  • The vehicle speed is 60 km/h (37 mph) or more.
  • *: w/ Retract Mirror
