INSPECTION

POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM OPER-
ATION INSPECTION

Inspection Procedure

INFOID:0000000006161763

Regarding Wiring Diagram information, refer to 

CHG-13, "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-III)

Perform ECM self-diagnosis with CONSULT-III. Refer to 

EC-49, "CONSULT-III 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-III 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 specification?

YES

>> Inspection End.

NO

>> GO TO 3.

3.

CHECK IPDM E/R (CONSULT-III)

Perform IPDM E/R self-diagnosis with CONSULT-III. Refer to 

PCS-13, "CONSULT - III 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

“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 %

1. Turn ignition switch OFF.

2. Disconnect generator connector E205 and IPDM E/R connector

E122.

3. Check continuity between generator harness connector E205

(A) terminal 4 and IPDM E/R harness connector E122 (B) termi-

nal 37.

4. Check continuity between generator harness connector E205

(A) terminal 4 and ground.

Are the continuity test results as specified?

YES

>> Replace IPDM E/R. Refer to 

PCS-28, "Removal and Installation of IPDM E/R"

.

NO

>> Repair harness or connector between IPDM E/R and generator.

B TERMINAL CIRCUIT

Description

INFOID:0000000006161764

The terminal “1” (B) circuit supplies power to charge the battery and operate the vehicles electrical system.

Diagnosis Procedure

INFOID:0000000006161765

Regarding Wiring Diagram information, refer to 

CHG-13, "Wiring Diagram"

.

1.

CHECK TERMINAL “1” CONNECTION

1. Turn ignition switch OFF.

2. Verify terminal “1” is clean and tight.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair terminal “1” connection. Confirm repair by performing complete Starting/Charging system

test. Refer to diagnostic station instruction manual.

2.

CHECK TERMINAL “1” CIRCUIT

Check voltage between generator connector E204 terminal 1 and

ground.

Is voltage reading as specified?

YES

>> GO TO 3.

NO

>> Check harness for open between generator and fusible

link.

3.

CHECK TERMINAL “1” CONNECTION (VOLTAGE DROP TEST)

1. Start engine, then engine running at idle and warm.

2. Check voltage between battery positive terminal and generator

connector E204 terminal 1.

Is the voltage reading as specified?

YES

>> Terminal “1” circuit is normal. Refer to 

CHG-4, "Work

Flow"

.

NO

>> Check harness between battery and generator for high resistance.
