STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
Stop the operation of the power generation voltage variable 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
DUTY value is 0 or 100 %, the normal power generation is performed according to the characteristic of the
IC regulator of the generator.)
• Turn the ignition switch OFF, and disconnect the battery current sensor connector. [However, DTC (P1550–
P1554) of the engine might remain. After finishing the inspection, connect the battery current sensor connec-
tor and erase the self diagnosis results history of the engine using CONSULT.]
>> GO TO 3.
3.
DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI
Perform the charging system test using Multitasking battery and electrical diagnostic station GR8-1200 NI or
Battery and electrical diagnostic analyzer EXP-800 NI. Refer to the applicable Instruction Manual for proper
testing procedures.
Test result
NO PROBLEMS>>Charging system is normal and will also show “DIODE RIPPLE” test result.
NO VOLTAGE>>GO TO 4.
LOW VOLTAGE>>GO TO 12.
HIGH VOLTAGE>>GO TO 14.
EXCESSIVE RIPPLE, OPEN PHASE, OPEN DIODE or SHORTED DIODE>>Replace the generator. Refer
to
CHG-28, "Removal and Installation"
. Perform “DIODE RIPPLE” test again using Multitasking
battery and electrical diagnostic station GR8-1200 NI or Battery and electrical diagnostic analyzer
EXP-800 NI to confirm repair.

STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
Stop the operation of the power generation voltage variable 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” with “Active Test”. Continue “Active Test” until the end of inspection. (When the
DUTY value is 0 or 100 %, the normal power generation is performed according to the characteristic of the
IC regulator of the generator.)
• Turn the ignition switch OFF, and disconnect the battery current sensor connector. [However, DTC (P1550 -
P1554) of the engine might remain. After finishing the inspection, connect the battery current sensor connec-
tor and erase the self-diagnostic results history of the engine using CONSULT.]
