4. FUNCTION DESCRIPTION AND INSPECTION OF
METER
CLUSTER
1) Tachometer - Engine RPM Display
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.
1. Connect the tachometer for tune-up test and start the engine.
2. Eliminate the hysteresis by tapping the tachometer.
3. Compare the values on the tester and tachometer and replace the tachometer if the
tolerance
is excessive.
If the tachometer pointer vibrates, stands at a certain range or sounds abnormal noise, there
could be defectives in tachometer. If there is a difference between actual engine speed (rpm)
and reading from tachometer, connect a scanner and then compare the value on tachomete
r
with the reading from scanner.

2) Speedometer
The speedometer indicates the vehicle speed by calculating the signals from the rear right
wheel speed sensor through ABS or ESP unit.
If the speedometer pointer vibrates, stands at a certain range or sounds abnormal noise, there
could be defectives in speedometer. However, these symptoms also could be appeared when
the tire has uneven wear, different tire inflation pressures or different tire specifications.
Perform the speedometer test regarding the tolerance as described. However, it is not simila
r
simple work in field due to lack of measuring conditions such as test equipment and
preciseness.
Check the allowable tolerance of the speedometer and operations of the trip odometer by
using a tester.
Check if the speedometer pointer is shaking and the abnormal noise sounds.
Eliminate the hysteresis by tapping the speedometer. 1.

3.
The allowable tolerance increases when the tires are worn or the tire pressure is out of
specified range. -

3) Fuel Level Gauge
The fuel level gauge displays the resistance value of the float on the fuel sender in the fuel tank
through a pointer. Note that this vehicle doesn’t have a service hole for checking the fuel
sender connector in the fuel tank.
The fuel sender and its connector can be checked and replaced only when the fuel tank is
removed. The power supply and resistance value should be measured at the connector in front
of the fuel sender (refer to wiring diagram).
When the power supply and output resistance are normal, the float operation by fuel level may
be defective; if so, replace the fuel sender.
Tolerance and resistance value by indicating angle
This table shows the tolerance and resistance value changes by fuel level in normal conditions.
Therefore, the differences that can be occurred by the road conditions and fuel fluctuations are
ignored.

4) Coolant Temperature Gauge
The coolant temperature gauge displays the coolant temperature with a pointer. The angle of
pointer that changes by coolant temperature is as shown below.
Measurement of coolant temperature sensor resistance
Measure the resistance between the terminal and the ground with an ohmmeter and replace i
f
the resistance is out of specified range.
Resistance value by coolant temperature:
20°C : 2449 Ω ±5 %
50°C : 826 Ω ±5 %
80°C : 321 Ω ±5 %
100°C : 112 Ω ±5 %
When the resistance value by coolant temperature is within the specified range, check
thermostat, water pump, radiator related coolant circuit for normal operation. Also, check the
wiring harnesses and connectors for proper connection.

5) TRIP ODOmeter (TRIP A, TRIP B) and ODOmeter
Reset button
Press and hold (over 1 sec.)
Trip odometer “TRIP A” and “TRIP B” will be reset to 0. (However, only the
corresponding driving range will be set to 0.) *
Press shortly (between 0.1 ~ 1 sec.)
The mode changes in order as shown in the figure. *
