Diagnosis Procedure
INFOID:0000000009482316
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-11, "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 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 %
