Inspection Procedure

INFOID:0000000006069245

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-57, "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” 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-III)

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

PCS-38, "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 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 %
