Power Generation Voltage Variable Control System Operation InspectionNKS003NQ
CAUTION:
For this model, the battery current sensor that is installed to the battery cable at the negative ter-
minal measures the charging/discharging current of the battery, and performs various controls. If
the electrical component or the ground wire is connected directly to the battery terminal, the cur-
rent other than that being measured with the battery current sensor is charging to or discharging
from the battery. This condition causes the malfunction of the control, and then the battery dis-
charge may occur. Never connect the electrical component or the ground wire directly to the bat-
tery terminal.
When performing this inspection, always use the charged battery that completed the battery
inspection. (When the charging rate of the battery is low, the response speed of the voltage
change will become slow. This is a cause of an incorrect inspection.)
INSPECTION PROCEDURE
1. CHECK ECM (CONSULT-II)
Perform ECM self-diagnosis with CONSULT-II. Refer to EC-133, "
CONSULT-II Function (ENGINE)"
(VQ35DE) or EC-846, "CONSULT-II Function (ENGINE)" (VK45DE).

-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-II 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%.
OK or NG
OK >> INSPECTION END
NG >> GO TO 3. (The charging condition of the battery should
be normal.)
3. CHECK IPDM E/R (CONSULT-II)
Perform IPDM E/R self-diagnosis with CONSULT-II. Refer to PG-20, "
CONSULT-II Function (IPDM E/R)" .

CAN Communication System DescriptionNIS0025S
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
