SYSTEM

REVERSE SOUND

The reverse sound is a function that operates when the selector lever is in the “R” position.

Operation Description

• The VCM transmits the following signals to the VSP control unit via CAN communication. 

- Shift position signal

- READY to drive indicator lamp request signal

• The VSP control unit judges that the reverse sound is necessary according to the signals received from the

VCM. 

• When the VSP control unit judges that operation of the reverse sound is necessary, it transmits the VSP

speaker signal to the VSP speaker. 

Operation Condition

The reverse sound operates when all of the following conditions are met. 

Operation Stop Condition

The reverse sound operation stops when any of the following conditions is met.

Signal Path

• The VSP control unit judges that the reverse sound is necessary according to the following signals, and

operates the reverse sound. 

• When the VSP control unit judges that the reverse sound is necessary, it transmits the following signal. 

No.

Description

When accelerating, the driving sound operates up to approximately 30 km/h (19 MPH). 

When the speed is more than 30 km/h (19 MPH), the driving sound stops. 

When decelerating, the driving sound operates when the speed is approximately 25 km/h (16 MPH) or less. 

The driving sound stops when the vehicle is stopped (fades out and stops).

 VSP SYSTEM OPERATION STOP AND RESUME FUNCTION

• The VSP system can be set to stop operating or to resume operating with the VSP OFF switch. 

• The VSP system starts operating when the power switch is turned from OFF to READY. 

• While operation of the VSP system is stopped, the VSP OFF indicator turns ON. 

Operation Description

• The VSP OFF switch transmits the VSP OFF switch signal to the VSP control unit. 

• The VSP control unit judges VSP system operation stop or operation resume according to the VSP OFF

switch signal.

• The VSP control unit transmits the VSP OFF indicator signal to the VSP OFF switch.

Stopping VSP System Operation

• Press the VSP OFF switch.

• Check that the VSP OFF indicator turns ON.

Cancelling VSP System Operation Stop

• Press the VSP OFF switch.

• Check that the VSP OFF indicator turns OFF.

NOTE:

Even if VSP system operation is stopped when the power switch is turned OFF, the VSP system starts to oper-

ate when the power switch is next turned from OFF to READY.

Signal Path

• The VSP control unit judges VSP system operation stop and operation resume according to the following

signal. 

• The VSP OFF switch turns the VSP OFF indicator lamp ON/OFF according to the following signal.

VSP SYSTEM MALFUNCTION DETECTION FUNCTION (Except for Mexico)

When a malfunction is detected in the VSP system, the VSP warning lamp turns ON. 

Signal Path

• When the VSP control unit detects a VSP system malfunction, it transmits the VSP warning lamp signal to

the VSP warning lamp.

• The VSP control unit turns the VSP warning lamp ON/OFF when the signal shown below is input.

VSP SYSTEM MALFUNCTION DETECTION FUNCTION (For Mexico)

When a malfunction is detected in the VSP system, the VSP OFF indicator turns ON. 

Signal Path

• When the VSP control unit detects a VSP system malfunction, it transmits the VSP OFF indicator signal to

the VSP OFF switch. 

• When the following signal is received, the VSP OFF switch turns the VSP OFF indicator lamp ON/OFF.

INFOID:0000000010121569

SYSTEM DIAGRAM

SYSTEM DESCRIPTION

• The charge sound system is a function which notifies the charge connector connected status, charge recep-

tion status, and charge port lid unlocked/normal charge connector unlocked status by the charge sound

request signal from VCM. 

• The charge sound system includes the following three sound types and operates linked with the charging

status indicator. 

- Plug-in detection sound

- Charge acceptance sound

- Charge port lid unlocked sound/normal charge connector unlocked sound

PLUG-IN DETECTION SOUND

• The plug-in detection sound notifies that the charger is connected correctly. 

• During rapid charging, the plug-in detection sound does not operate. 

Operation Description

• The VCM transmits the charge sound request signal (plug-in detection sound) to the VSP control unit via

CAN communication.
