2. CONFIGURATION
1) RPM Gauge
The tachometer indicates engine speed in revolutions per minute. Multiply 1,000 to the current
number, then it will be the current number of engine revolutions.
Under the normal engine operating temperature, the proper idling speed is 700 ~ 800 rpm. The
red zone (danger rpm range) starts from 4,500 rpm.
Connect the tachometer for tune-up test and start the engine.
Eliminate the hysteresis by tapping the tachometer.
Compare the values on the tester and tachometer and replace the tachometer if the tolerance
is excessive. 1.
2.
3.
If the tachometer (engine rpm gauge) pointer vibrates or stops moving at a certain range, or
abnormal noises are heard from the tachometer, the tachometer may have a malfunction. If
you have reason to suspect that the reading from the tachometer differs from the actual engine
speed (rpm), connect a diagnostic device and compare the value on tachometer with the
reading from the diagnostic device.

3. WARNING LIGHTS AND INDICATORS
ESP OFF Indicator
This lamp comes on when pressing
the "ESP OFF" switch or the ESP
system is defective. When the ESP
system is activated, this lamp blinks
and a chime sounds.
Immobilizer Indicator
This indicator comes on when the
ignition key is communicating with
the engine control unit for approx.
0.5 seconds.
Glow Indicator
When the ignition key is turned ON,
this indicator lamp comes on and the
combustion chamber is warmed up.
In the vehicle equipped with direct
injection type engine, this indicator
may come on very shortly or may not
come on.
Fog Lamp / Headlamp
High Beam Indicator
This lamp comes on when
the fog lamp or high beam
headlamp operates to
indicate the operating
status.Engine Oil Pressure Warning Ligh
This lamp comes on if there is any
fault in the engine oil system and
goes off when a certain amount of
time has elapsed after turning ON
the ignition switch.
Door ajar warning
light
This light comes on
when a door or
tailgate is either
opened or not
closed completely.Brake warning light
This warning light comes on
and warning buzzer sounds
when the parking brake is
applied and/or the brake fluid
level is lower than specified
level.Seat belt warning lamp
The seat belt warning light comes on
and the seat belt warning chime
sounds for 6 seconds when the
ignition switch is turned to "ON"
position unless the driver's seat belt is
securely fastened. This reminding
operation stops when the driver
fastens the seat belt.
Engine Coolant Overheat
Warning Light
When the coolant temperature is
abnormally hot (over 120℃), this
warning light blinks and a
warning buzzer sounds at 1 Hz.
(check cooling system)

04-218210-01
ABS Warning Light
This warning light comes on
when the ignition switch is
turned to "ON" position and
should go out if the system is
normal.
The vehicle with ABS performs
self-diagnosis. During this
diagnosis, brake pedal
vibration and noise may be
apparent when the driving
motors discharges the
hydraulic pressure from the
internal hydraulic device.4WD IndicatorLow Fuel Level
Warnig Light
This warning light
comes on when the
fuel will soon be
exhausted. The time
it takes turn on,
however, varies
according to the
gradient of the
vehicle.
4WD HIGH Indicator
The lamp blinks momentarily during
the change of driving mode.
4WD LOW Indicator
The lamp blinks momentarily during
the change of driving mode.
4WD CHECK Warning Light
This indicates that there is
something wrong in the transfer
case system. (check the system) -
-
-
Auto Cruise Control
Indicator
Operating the cruise
control switch turns on
the indicator lamp to
indicate the cruise
control system is
activated.
Water Separator Warning Light
This lamp comes on to warn the driver of
water in the fuel tank which causes the
loss of engine power. When a certain
amount of water is accumulated, the lamp
comes on and a chime sounds.
Engine CHECK Warning Light
This warning light comes on when
the ignition switch is turned to "ON"
position and should go out if the
system related to engine control is
normal.
This comes on when different
sensors and devices related to
engine control are defective.
Winter Mode
Indicator
Pressing the "W" side of the
automatic transmission mode
selector switch switches the
driving mode to winter mode and
turns on the indicator lamp.
Use this mode to drive off
smoothly on icy and slippery
roads.
Charge Warning Light
This warning light comes on when the
ignition switch is turned on and go off
when the engine is started.
If this light doesn't go off after engine
starting, it means there is a malfunction in
the system.
Engine Hood Open Warning Light
When the engine hood is open, this light
comes on to inform the driver.

How to enter self-diagnosis mode ▶
Turn the ignition ON with the TRIP switch pressed.
Press and hold the TRIP switch for 5 to 10 sec. with the ignition ON.
Press and hold the TRIP switch for less than 10 sec. and then cycle the switch between ON
and OFF 5 times within 3 sec.
Confirm that the self-diagnosis mode is activated through the instrument cluster. 1.

4. SELF-DIAGNOSIS CHECK
Self-diagnosis OFF ▶
If the engine speed increases to 396 rpm or more while the engine is cranking or the ignition key
is turned OFF in self-diagnosis mode, the self-diagnosis mode is turned OFF automatically.
Operating process ▶
Speed gauge: changes from 0 to 220 km
RPM gauge: changes from 0 to 6,000 rpm
Fuel gauge: changes from E to F
Temperature gauge: changes from C to H
Warning/Indicator lamps: All indicator/warning lamps controlled by MICOM are turned ON.
Dimming: Illuminates at the highest lighting level.

3) Transmission Control Monitoring System
TCU monitors all input and output signals to identify possible failures. If a fault is detected, TCU

Monitoring the Supply Voltage ▶
Monitoring the Supply Voltage to Solenoid ▶
Monitoring the Gear Ratio ▶
Monitoring the Torque Converter ▶ If the battery voltage is too high or too low, the TCU sets the DTC.
TCU monitors the circuits for open or short to ground or supply. The monitoring function
evaluates the voltage characteristics while the switch is ON.
TCU monitors the gear is engaged properly in the allowed time.
TCU checks if the torque converter can be locked up properly. If it is failed, TCU releases the
torque converter clutch to activate the fail-safe operation.
4) Shift Energy Management
This function involves reducing or increasing the engine output torque during shifting. This
reduces the energy which is dissipated in the friction elements of the transmission during up-
shift. This is done by reducing the engine torque during the gear ratio change without interrupting
the tractive drive.
This function is used for:
Increasing the life span of transmission by shortening the slipping time
Improving the shift comfort by reducing the step changes due to gearshift
Transferring a higher engine power -
-
-
Real-time control of engine torque is required to maintain the proper shift operations and the
durability of transmission. TCU controls the engine torque during the gearshift by synchronizing
the operation of transmission clutches.
