2.STOP POWER GENERATION VOLTAGE 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
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 batte ry 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.
Te s t r e s u l t
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-29, "
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.
4.INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS ON)
Turn the ignition switch ON.
Does the charge warning lamp illuminate?
YES >> GO TO 6.
NO >> GO TO 5.
5.“L” TERMINAL CIRCUIT (OPEN) INSPECTION
Check “L” terminal circuit (open). Refer to CHG-24, "
Diagnosis Procedure".
Is the
“L” terminal circuit normal?
YES >> Replace generator. Refer to CHG-29, "Removal and Installation".
NO >> Repair as needed.
6.INSPECTION WITH CHARGE WARNING LAMP (IDLING)
Start the engine and run it at idle.
Does the charge warning lamp turn OFF?
YES >> GO TO 9.
NO >> GO TO 7.
7.“L” TERMINAL CIRCUIT (SHORT) INSPECTION
Check “L” terminal circuit (short). Refer to CHG-26, "
Diagnosis Procedure".
Is the
“L” terminal circuit normal?
YES >> GO TO 8.
NO >> Repair as needed.
8.“S” TERMINAL CIRCUIT INSPECTION
Check “S” terminal circuit. Refer to CHG-27, "
Diagnosis Procedure".
Is the
“S” terminal circuit normal?
YES >> GO TO 10.

1.PRELIMINARY INSPECTION
Perform the preliminary inspection. Refer to CHG-20, "
Diagnosis Procedure".
>> GO TO 2.
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” 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 batte ry 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.]
>> GO TO 3.
3.INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS TURNED ON)
When ignition switch is turned ON.
Does the charge warning lamp illuminate?
YES >> GO TO 4.
NO >> GO TO 10.
4.INSPECTION WITH CHARGE WARNING LAMP (IDLING)
Start the engine and run it at idle
Does the charge warning lamp turn OFF?

Regarding Wiring Diagram information. Refer to CHG-9, "Wiring Diagram".
CAUTION:
When performing this inspection, always use a charged battery that has completed the battery inspec-
tion. (When the charging rate of the battery is low, the response speed of the voltage change will
become slow. This can cause an incorrect inspection.)
1.CHECK ECM (CONSULT)
Perform “Self Diagnostic Result” of “ECM” with CONSULT. Refer to EC-60, "
CONSULT Function".
Self
-diagnostic results content
No malfunction detected>> GO TO 2.
Malfunction detected>> Check applicable parts, and repair or replace corresponding parts.
2.CHECK OPERATION OF POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
1. Connect CONSULT and start the engine.
2. The selector lever is in “P” or “N” position and a ll of the electric loads and A/C, etc. are turned OFF.
3. Select “ALTERNATOR DUTY” in “Active Test” of “ENGINE”, and then check the value of “BATTERY
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.
3.CHECK IPDM E/R (CONSULT)
Perform “Self Diagnostic Result” of “I PDM E/R” with CONSULT. Refer to PCS-10, "
CONSULT Function (IPDM
E/R)".
Is the inspection result normal?
No malfunction detected>> GO TO 4.
Malfunction detected>> Check applicable parts, and repair or replace corresponding parts.
4.CHECK HARNESS BETWEEN GE NERATOR AND IPDM E/R
1. Turn ignition switch OFF.
2. Disconnect generator connector and IPDM E/R connector.
3. Check continuity between generator harne ss connector and IPDM E/R harness connector.
“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 %
