Auto Active TestNKS004E7
DESCRIPTION
In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to the
following systems:
Rear window defogger
Front wiper (LO, HI)
Tail lamps, parking lamps and license plate lamps
Front fog lamps
Headlamps (LO, HI)
A/C compressor (magnetic clutch)
Cooling fan
Oil pressure warning lamp
OPERATION PROCEDURE
1. Close hood and front door (passenger side), and then lift wiper arms away from windshield (to prevent
glass damage by wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON, and within 20 seconds, press driver's door switch 10 times (close other doors).
Then turn ignition switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, horn chirps once. Oil pressure warning lamp starts blinking.
6. After a series of operations is repeated three times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Never start the engine.
If the engine starting operation is made, delete DTC on the self-diag results of CONSULT-II.
Refer to BL-81, "
CONSULT-II Application Items" .
Be sure to inspect GW-52, "Door Switch Check" when the auto active test cannot be performed.

On-Vehicle Inspection and ServiceNGS000DE
CHECKING RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
1. Connect the hydraulic pressure gauge [SST] between oil pump
discharge connector and high-pressure hose. Bleed air from the
hydraulic circuit while opening valve fully. Refer to PS-8, "
Air
Bleeding Hydraulic System" .
2. Start engine. Run engine until oil temperature reaches 50 to
80
C (122 to 176F).
CAUTION:
Leave the valve of the hydraulic pressure gauge [SST]
fully open while starting and running engine. If engine is
started with the valve closed, the hydraulic pressure in
oil pump goes up to the relief pressure along with
unusual increase of oil temperature.
Be sure to keep hose clear of belts and other parts when
engine is started.
3. Fully close the hydraulic pressure gauge [SST] valve with
engine at idle and measure the relief oil pressure.
CAUTION:
Never keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Repair oil pump is the
relief oil pressure is outside the standard. Refer to PS-30, "
Dis-
assembly and Assembly (Models with VK45DE)" , PS-34, "Disassembly and Assembly (Models with
VQ35DE)" .
5. After inspection, disconnect the hydraulic pressure gauge [SST] from hydraulic circuit, then add fluid and
bleed air. Refer to PS-8, "
Air Bleeding Hydraulic System" .

2. Connect “CONSULT-II” and “CONSULT-II CONVERTER” to the
data link connector (1).
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.

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).

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%.

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.
