POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM OPERATION INSPECTION


Inspection Procedure

Regarding Wiring Diagram information, Electrical Diagrams.

CAUTION:
When performing this inspection, always use a charged battery that has completed the battery inspection. (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. CONSULT-III Function (Engine)(VQ40DE) or CONSULT-III Function (Engine) (VK56DE).
Is the inspection result normal?
YES - GO TO 2
NO - 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 inspection result normal?
YES - Inspection End.
NO - GO TO 3
3.CHECK IPDM E/R (CONSULT-III)
Perform IPDM E/R self-diagnosis with CONSULT-III. CONSULT-III Function (IPDM E/R).
Is the inspection result normal?
YES - GO TO 4
NO - 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 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) terminal 37.






4. Check continuity between generator harness connector E122
(A) terminal 4 and ground.






Is the inspection result normal?
YES - Replace IPDM E/R. Service and Repair.
NO - Repair harness or connector between IPDM E/R and generator.
