Operation

Note

•  For the audio amplifier operation, refer to the AUDIO SYSTEM.

Engine restart by i-stop (With i-stop system)

1.  The PCM sends a boost request signal to the DC-DC converter and audio amplifier when the engine is restarted by the i-stop control.

2.  The DC-DC converter increases the electric current voltage to the audio unit, and when the audio amplifier receives the increase request signal, it controls the output current to the speakers at 10 A or less.

Note

•  If the audio amplifier performs current control when the audio volume is 50 or more, the audio volume may decrease for approx. 0.3 s.
