3. CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1. Start engine, then engine running at idle and warm.
2. Check voltage between battery positive terminal and alternator
“B” terminal.
OK or NG
OK >> Go to SC-25, "Trouble Diagnosis with Starting/Charging
System Tester (Charging)" .
NG >> Check harness between battery and alternator for poor continuity.
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 the following.

2. Driver door switch is ON (open) → OFF (close) → ON (open).
3. END
Procedure B
1. Drive the vehicle at more than 25 km/h (16 MPH).
2. END
SETTING CHANGE FUNCTION
The settings of the automatic driving positioner system can be changed, using CONSULT-II and the display
unit in the center of the instrument panel.
×: Applicable –: Not applicable
It is possible to set sliding driver seat for entry/exit of vehicle by pressing set switch.
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.
CAN Communication UnitNIS0025T

Trouble Diagnoses Symptom ChartNIS0027O
NOTE:
Make sure other systems using the signal of the following systems operate normally.
NOTE:

The climate controlled seat blower keep low speed for approximately 60 seconds turning the switch.

The climate controlled seat system is downed when the temperature sensor set as the seat cushion and
the seatback's thermal electric device machine detects 20 °C (68°F) or more of mutual differences of tem-
perature.
Preliminary CheckNIS0027N
1. CHECK DUCT AND FILTER
Check the following.

Is that there no foreign body in the blower motor filter.

Is that there no foreign body in the duct.
OK or NG
OK >> Preliminary check is OK.
NG >> The foreign body is removed.

TROUBLE DIAGNOSIS
Revision: 2007 April2007 M35/M45
CONSULT-II FunctionNHS00094
DIAGNOSIS MODE FOR CONSULT-II

“SELF-DIAG [CURRENT]”
A current self-diagnosis results (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring
repairs.

“SELF-DIAG [PAST]”
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.

“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.

“ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned
with its own, individual classification number. This number will
be displayed on the CONSULT-II screen, as shown. When
replacing the diagnosis sensor unit, refer to the part number for
the compatibility. After installation, replacement with a correct
unit can be checked by confirming this classification number on
the CONSULT-II screen.
After repair, make sure the discriminated number of diagnosis
sensor unit installed to vehicle are same. Refer to SRS-52,
"ECU DISCRIMINATED NO." .

PASSENGER AIR BAG
The STATUS (Readiness) of the front passenger air bag module is displayed.The STATUS displayed
(ON/OFF) depends on the signals supplied to the occupant classification system control module and
air bag diagnosis sensor unit. Refer to SRS-7, "
Occupant Classification System (OCS)" for more infoma-
tion.
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-II
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears, then diagnosis mode automatically changes to User mode.

HOW TO ERASE SELF-DIAGNOSTIC RESULTS

“SELF-DIAG [CURRENT]”
A current self-diagnosis result is displayed on the CONSULT-II screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.

“SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-II screen by touching “BACK” key of CONSULT-II and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is not erased, the User mode shows the system
malfunction by the operation of the warning lamp even if the malfunction is repaired completely.

“TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-II)NHS00095

The reading of these results is accomplished “User mode” and “Diagnosis mode”.

After a malfunction is repaired, turn ignition switch ON. Diagnosis mode returns to the User mode. At that
time, the self-diagnosis result is cleared.
HOW TO CHANGE SELF-DIAGNOSIS MODE WITHOUT CONSULT-II
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
After a malfunction is repaired, turn the ignition switch OFF for at least one second, then back ON. Diagnosis
mode returns to the User mode. At that time, the self-diagnosis result is cleared.
