YES
>> GO TO 3
NO
>> Be sure to eliminate cause of malfunction before installing new fuse or fusible link.
3.
CHECK GENERATOR GROUND TERMINAL CONNECTION
Check if connector E230 terminal 5 (generator ground harness) is clean and tight.
Is the inspection result normal?
YES
>> GO TO 4
NO
>> Repair connection.
4.
CHECK DRIVE BELT TENSION
Check drive belt tension. Refer to
Is the inspection result normal?
YES
>> Inspection End.
NO
>> Repair as needed.

ATION INSPECTION
Diagnosis Procedure
INFOID:0000000009465971
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 “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-13, "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 GENERATOR AND IPDM E/R
1. Turn ignition switch OFF.
2. Disconnect generator connector and IPDM E/R 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 %

3. Check continuity between generator harness connector F7 (A)
terminal 4 and IPDM E/R harness connector F10 (B) terminal
76.
4. Check continuity between generator harness connector F7 (A)
terminal 4 and ground.
Is the inspection result normal?
YES
>> Replace IPDM E/R. Refer to
PCS-35, "Removal and Installation"
NO
>> Repair harness or connector between IPDM E/R and generator.

B TERMINAL CIRCUIT
Description
INFOID:0000000009465972
“B” terminal circuit supplies power to charge the battery and operate the vehicle’s electrical system.
Diagnosis Procedure
INFOID:0000000009465973
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 “1” 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 “B” TERMINAL CIRCUIT
Check voltage between generator connector F6 terminal 1 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 F6 terminal 1.
Is the inspection result normal?
YES
>> “B” terminal circuit is normal. Refer to
Flow (With EXP-800 NI or GR8-1200 NI)"
"Work Flow (Without EXP-800 NI or GR8-1200 NI)"
NO
>> Check harness between battery and generator for high
resistance.
