POWER GENERATION VOLTAGE VA RIABLE CONTROL SYSTEM OPER-
ATION INSPECTION
Diagnosis ProcedureINFOID:0000000009460660
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.)
1.CHECK ECM (CONSULT)
Perform ECM self-diagnosis with CONSULT. Refer to EC-77, "CONSULT Function"
(QR25DE) or EC-601,
"CONSULT Function" (VQ35DE).
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 al l 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 IPDM E/R self-diagnosis with CONSULT. Refer to PCS-9, "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 harnes s 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 %

using the EXP-800 NI or GR8-1200 NI (if availabl e). Refer to applicable Instruction Manual for
proper testing procedures.
2.CHECK “B” TERMINAL CIRCUIT
Check voltage between generator “B” terminal and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Check harness for open between generator and fusible link.
3.CHECK “B” TERMINAL CONNECT ION (VOLTAGE DROP TEST)
1. Start engine, then engine running at idle and warm.
2. Check voltage between battery positive te rminal and generator connector “B” terminal.
Is the inspection result normal?
YES >> “B” terminal circuit is normal. Refer to CHG-17, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
or CHG-20, "Work Flow (Without EXP-800 NI or GR8-1200 NI)".
NO >> Check harness between battery and generator for continuity.

DescriptionINFOID:0000000009460663
The “L” terminal circuit controls the charge warning
lamp. The charge warning lamp turns ON when the igni-
tion switch is set to ON or START. When the generator is providing sufficient voltage with the engine running,
the charge warning lamp turns OFF. If the charge warn ing lamp illuminates with the engine running, a malfunc-
tion is indicated.
Diagnosis ProcedureINFOID:0000000009460664
Regarding Wiring Diagram information. Refer to CHG-12, "Wiring Diagram".
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 applicable Instruction Manual for proper
testing procedures.
2.CHECK “L” TERMINAL CIRCUIT (OPEN)
1. Disconnect the generator connector.
2. Apply ground to generator 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-17, "Work Flow (With EXP-800 NI or GR8-1200 NI)" or
CHG-20, "Work Flow (Without EXP-800 NI or GR8-1200 NI)"
.
