SYSTEM DIAGRAM

SYSTEM DESCRIPTION

• The start up sound is a function that produces a sound that is linked with the power switch operation and

with the READY to drive indicator lamp on the combination meter.

• The start up sound consists of the following two types.

- The power switch operation sound, which operates when the power switch is operated. 

- The READY effect sound, which is linked with the READY to drive indicator lamp on the combination meter. 

• Four sound types (including OFF) can be selected for the start up sound. 

• The type of start up sound can be set in the combination meter. 

POWER SWITCH OPERATION SOUND

The power switch operation sound is a function that operates when the power switch is pressed.

Operation Description

• The VSP control unit judges power switch operation according to the power switch signal from the BCM. 

• When the power switch signal is received, the VSP control unit transmits the start up sound speaker signal

to the start up sound speaker. 

Operation Condition

When the following conditions are met, the power switch operation sound operates.

If the power switch is pressed and released quickly, the power switch operation sound may not sound linked

with the switch. 

Operation Stop Condition

When any of the following conditions is met, the power switch operation sound stops. 

Signal Path

• The VSP control unit judges that the power switch operation sound is necessary according to the following

signal, and operates the power switch operation sound. 

• When the VSP control unit judges that the power switch operation sound is necessary, it transmits the fol-

lowing signal.

READY EFFECT SOUND

The READY effect sound is a function that operates linked with the READY to drive indicator lamp on the com-

bination meter. 

Operation Description

• The VCM transmits the READY to drive indicator lamp request signal to the VSP control unit via CAN com-

munication.
