CHECK DOOR LOCK/UNLOCK SWITCH
WITH CONSULT-II
Check door lock/unlock switch signal (“CDL LOCK SW” or “CDL UNLOCK SW”) in “DATA MONITOR” mode with CON-
SULT-II.
MKIB0198E
When door lock/unlock is locked:
CDL LOCK SW ON
CDL UNLOCK SW OFF
When door lock/unlock is unlocked:
CDL LOCK SW OFF
CDL UNLOCK SW ON
WITHOUT CONSULT-II
Check voltage between smart entrance control unit harness connector M99 terminals 13 (GY), 14 (L) and ground.

System Description
NLEL0442
UNIFIED CONTROL METER
NLEL0442S01
I
Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit built-in combination meter.
I
Digital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
I
Odo/trip meter segment can be checked in diagnosis mode.
I
Meter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
NLEL0442S02
YEL329E
NOTE:
Turn ignition switch to the “ON” position to operate odo/trip meter.

POWER SUPPLY AND GROUND CIRCUIT
=NLEL0442S03
Power is supplied at all times
I
through 10A fuse [No. 12, located in the fuse block (J/B)]
I
to combination meter terminal 3.
With the ignition switch in the ON or START position, power is supplied
I
through 10A fuse [No. 30, located in the fuse block (J/B)]
I
to combination meter terminal 2.
With the ignition switch in the ACC or ON position, power is supplied
I
through 10A fuse [No. 1, located in the fuse block (J/B)]
I
to combination meter terminal 5.
Ground is supplied
I
through body grounds M28, M48, M109 (QG engine) or F51 (YD engine)
I
to combination meter terminal 7.
WATER TEMPERATURE GAUGE
NLEL0442S04
The water temperature gauge indicates the engine coolant temperature.
ECM provides a engine coolant temperature signal to combination meter for water temperature gauge via CAN
communication line.
TACHOMETER
NLEL0442S05
The tachometer indicates engine speed in revolution per minutes (rpm). ECM provides an engine speed sig-
nal to combination meter for tachometer via CAN communication line.
FUEL GAUGE
NLEL0442S06
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
I
from body grounds M28, M48, M109 (QG engine) or F51 (YD engine)
I
through terminals 4 and 26 of combination meter,
I
through terminal 1 of the fuel level sensor unit and
I
through terminal 4 of the fuel level sensor unit
I
to combination meter terminal 25 for the fuel gauge.
SPEEDOMETER
NLEL0442S07
The combination meter receives a signal from the ABS actuator and electric unit (control unit) via CAN com-
munication line. The speedometer converts the signal into the vehicle speed displayed.

Combination Meter Self-Diagnosis
NLEL0447
PERFORMING SELF-DIAGNOSIS MODE
NLEL0447S01
1.
Turn the ignition switch to the “LOCK” position.
2.
Press odo/trip meter switch on the combination meter and
keep them depressed.
3.
Turn the ignition switch to the “ON” position, while keeping the
odo/trip meter switch pressed.
4.
Release odo/trip meter switch then self-diagnosis will start.
The sequence (A to J) is activated by press the either odo/trip
meter switch.
NOTE:
If either odo/trip meter switch is not pressed for 20 seconds at each
step or if the ignition switch is turned OFF, the self-diagnosis mode
is exited.
