CIRCUIT DIAGRAMSB-85
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).

NOTE
If the engine-ECU is replaced, the immobilizer-ECU and
ignition key should be replaced together with it.
DIAGNOSIS FUNCTION
ENGINE WARNING LAMP (CHECK ENGINE LAMP)
If an abnormality occurs in any of the following items related
to the MPI system, the engine warning lamp will illuminate
or flash. If the lamp remains illuminated or if the lamp
illuminates while the engine is running, check the diagnosis
code output.
However, the warning lamp will illuminate as bulb check for
5 seconds whenever the ignition switch is turned to the ON
position.
