POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM OPER-
ATION INSPECTION
Inspection Procedure
INFOID:0000000012200373
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 ECM self-diagnosis with CONSULT. Refer to
(For NISMO RS models)
(Except for NISMO RS models).
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. Check that the selector lever is in “P” or “N” position (CVT models) or shifter lever is in neutral position (M/
T models) and that all of the electric loads and A/C, etc. are turned OFF.
3. Select “ALTERNATOR DUTY” at “Active Test” of “ENGINE”, and then check the value of “BATTERY
VOLT” monitor when DUTY value of “ALTERNATOR DUTY” is set to 40.0 %.
4. Check the value of “BATTERY VOLT” monitor when DUTY value of “ALTERNATOR DUTY” is set to
80.0%.
Is the measurement value within the specification?
YES
>> INSPECTION END
NO
>> GO TO 3.
3.
CHECK IPDM E/R (CONSULT)
Perform IPDM E/R self-diagnosis with CONSULT. Refer to
PCS-14, "CONSULT Function (IPDM E/R)"
.
Self-diagnostic results content
No malfunction detected>> GO TO 4.
Malfunction detected>> Check applicable parts, and repair or replace corresponding parts.
4.
CHECK HARNESS BETWEEN ALTERNATOR AND IPDM E/R
1. Turn ignition switch OFF.
2. Disconnect alternator connector and IPDM E/R connector.
3. Check continuity between alternator harness connector and IPDM E/R harness connector.
4. Check continuity between alternator harness connector and ground.
“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 %

B TERMINAL CIRCUIT
Description
INFOID:0000000012200374
“B” terminal circuit supplies power to charge the battery and to operate the vehicle’s electrical system.
Diagnosis Procedure
INFOID:0000000012200375
1.
CHECK “B” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “B” terminal is clean and tight.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair “B” terminal connection. Confirm repair by performing complete Charging system test
using EXP-800 NI or GR8-1200 NI (if available). Refer to the applicable Instruction Manual for
proper testing procedures.
2.
CHECK “B” TERMINAL CIRCUIT
Check voltage between alternator “B” terminal and ground.
For NISMO RS models
Except for NISMO RS models
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Check harness for open between alternator and fusible link.
3.
CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Start engine, then engine running at idle and warm.
2. Check voltage between battery positive terminal and alternator “B” terminal.
For NISMO RS models
Except for NISMO RS models
Is the inspection result normal?
YES
>> “B” terminal circuit is normal. Refer to
CHG-15, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
or
CHG-19, "Work Flow (Without EXP-800 NI or GR8-1200 NI)"
.
NO
>> Check harness between battery and alternator for poor continuity.

L TERMINAL CIRCUIT (OPEN)
L TERMINAL CIRCUIT (OPEN)
Description
INFOID:0000000012200376
The “L” terminal circuit controls the charge warning lamp. The charge warning lamp illuminates when the igni-
tion switch is set to ON or START. When the alternator is providing sufficient voltage with the engine running,
the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a malfunc-
tion is indicated.
Diagnosis Procedure
INFOID:0000000012200377
1.
CHECK “L” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “L” terminal is clean and tight.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair “L” terminal connection. Confirm repair by performing complete Charging system test
using EXP-800 NI or GR8-1200 NI (if available). Refer to the applicable Instruction Manual for
proper testing procedures.
2.
CHECK “L” TERMINAL CIRCUIT (OPEN)
1. Disconnect alternator connector.
2. Apply ground to alternator harness connector terminal.
3. Check condition of the charge warning lamp with the ignition switch in the ON position.
Does it illuminate?
YES
>> “L” terminal circuit is normal. Refer to
CHG-15, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
CHG-19, "Work Flow (Without EXP-800 NI or GR8-1200 NI)"
.
NO
>> GO TO 3.
3.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the battery cable from the negative terminal.
2. Disconnect the combination meter connector.
3. Check continuity between alternator harness connector and combination meter harness connector.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair the harness or connector.
4.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
Check continuity between combination meter harness connector M34 terminal 28 and 10A fuse [No.5 located
in the fuse block (J/B)].
Does continuity exist?
YES
>> GO TO 5.
NO
>> Repair the harness.
5.
CHECK POWER SUPPLY CIRCUIT
1. Connect the battery cable to the negative terminal.
2. Check voltage between combination meter harness connector and ground.
