2.STOP POWER GENERATION VOLT
AGE VARIABLE CONTROL SYSTEM
Stop the operation of the power generation voltage variabl e control in either of the following procedures.
• After selecting “ENGINE” using CONSULT, set the DUTY value of “ALTERNATOR DUTY” to 0 % by select- ing “ALTERNATOR DUTY” of “Active Test”. Continue “Active Test” until the end of inspection. (When the

Regarding Wiring Diagram information. Refer to CHG-12, "Wiring Diagram".
CAUTION:
When performing this in spection, always use a charged battery that has completed the battery inspec-
tion. (When the charging rate of the battery is lo w, the response speed of the voltage change will
become slow. This can cause an incorrect inspection.)

VOLT” monitor when DUTY value of “DUTY” is set to 40.0 %.
4. Check the value of “BATTERY VOLT” monitor when DUTY value of “DUTY” is set to 80.0%.
Is the inspection result normal?
YES >> Inspection End.
NO >> GO TO 3.

“BATTERY VOLT”
2 seconds after setting the
DUTY value of “ALTERNA-
TOR DUTY” to 40.0 % : 12 - 13.6 V
“BATTERY VOLT”
20 seconds after setting
the DUTY value of “ALTER-
NATOR DUTY” to 80.0 % : +0.5 V or more against
the value of “BATTERY
VOLT” monitor when
DUTY value is 40.0 %
