CHARGING SYSTEM (See P.B-84.)
OPERATION
When engine is stationary
DWhen the ignition switch is turned to the ON
position, current flows the alternator L terminal
and, at the same time, the charge warning lamp
illuminates.
When engine is started and after engine has
started
DWhen the engine is started, the charge warning
lamp goes out because of the charging voltage
begin applied to the alternator L terminal.
DThe battery voltage being applied to the
alternator S terminal is monitored by the voltage
regulator. Therefore, the amount of electricity
produced by the alternator is controlled by
allowing and cutting off the current flowing to
the field coil.
DThe alternator B terminal supplies power to
each load.TROUBLESHOOTING HINTS
1. Charging indicator lamp does not illuminate
when the ignition switch is turned to ON
position, before the engine starts.
DCheck multi-purpose fuse No.(2).
DCheck the bulb.
2. Charging indicator lamp fails to switch off once
the engine starts.
DCheck voltage regulator of alternator.
3. Discharged or overcharged battery.
DCheck voltage regulator of alternator.
4. Charge warning lamp illuminates dimly.
DCheck combination meter diode (for short).

GENERAL INFORMATION
SUPERCHARGING PRESSURE CONTROL
By controlling the duty of the waste gate solenoid valve, the waste gate actuator functions to control the supercharging
pressure. This allows a supercharged pressure matching the engine operation state to be attained. Control is carried
out to prevent excessive supercharging and thereby prevent engine damage.
SECONDARY AIR CONTROL
When decelerating during high-speed travel, the secondary air is introduced into the upstream of the turbocharger
to prevent the turbine speed from dropping and to increase the acceleration responsiveness after deceleration.
The secondary air is introduced into each cylinder of the exhaust manifold to maximize the effect.
