YES
>> GO TO 3.
NO
>> Replace the blown fuse or fusible link after repairing the affected circuit.
3.
CHECK GENERATOR GROUND TERMINAL CONNECTION
Check if connector F17 terminal 5 and 6 is clean.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair connection.
4.
CHECK DRIVE BELT TENSION
Check drive belt tension. Refer to
CHG-29, "Removal and Installation"
Is the inspection result normal?
YES
>> Inspection End.
NO
>> Repair as needed.

ATION INSPECTION
Diagnosis Procedure
INFOID:0000000009755964
Regarding Wiring Diagram information. Refer to
.
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
.
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 all 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-10, "CONSULT Function (IPDM E/R)"
Intelligent Key system) or
PCS-38, "CONSULT Function (IPDM E/R)"
(without Intelligent Key system).
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 GENERATOR AND IPDM E/R
1. Turn ignition switch OFF.
2. Disconnect generator connector and IPDM E/R connector.
3. Check continuity between generator harness 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 %

INSPECTION
4. Check continuity between generator harness connector and ground.
Is the inspection result normal?
YES
>> Replace IPDM E/R. Refer to
PCS-30, "Removal and Installation"
NO
>> Repair harness or connectors between IPDM E/R and generator.

B TERMINAL CIRCUIT
Description
INFOID:0000000009755965
“B” terminal circuit supplies power to charge the battery and to operate the vehicles electrical system.
Diagnosis Procedure
INFOID:0000000009755966
Regarding Wiring Diagram information. Refer to
.
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 terminal “B” connection. Confirm repair by performing complete Charging system test
using the EXP-800 NI or GR8-1200 NI (if available). Refer to applicable Instruction Instruction 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 CONNECTION (VOLTAGE DROP TEST)
1. Start engine, then engine running at idle and warm.
2. Check voltage between battery positive terminal and generator connector “B” terminal.
Is the inspection result normal?
YES
>> “B” terminal circuit is normal. Refer to
CHG-14, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
or
CHG-17, "Work Flow (Without EXP-800 NI or GR8-1200 NI)"
.
NO
>> Check harness between battery and generator for continuity.
