Indicators
The instrument cluster assembly includes the following indicators:
| • | The daytime running lamps |
| • | The malfunction indicator lamp (Service Engine Soon) |
| • | The seat belt on reminder |
The indicators are serviceable from the rear of the cluster assembly.
Refer to
Instrument Cluster Bulb Replacement
.
The instrument cluster assembly indicators may differ from model to
model, depending on the following factors:
| • | The transaxle selection |
Gauges
The instrument cluster assembly will include different combinations
of the following gauges, depending on the above factors:
| • | The Engine Coolant Temperature (ECT) gauge |
| • | An optional engine tachometer |
| • | A combination fuel and temperature gauge |
The gauges are all serviceable from the cluster assembly. Refer to
Fuel Gage Replacement
,
Tachometer Replacement
,
Engine Coolant Temperature Gage Replacement
or
Fuel/Temperature Gage Replacement
for gauge removal and installation procedures.
Speedometer
Notice: When replacing a speedometer/odometer assembly, the law requires that
the odometer reading of the replacement unit be set in order to register the
same mileage as the prior odometer. If the same mileage cannot be set, the
law requires that the replacement odometer be turned to zero. A label must
be installed on the driver's door frame in order to show the previous odometer
reading and the date of replacement.
The speedometer is a good road indicator using an odometer
for recording total mileage.
The speedometer is an electrically driven instrument.
The indicator needle is oversprung in order to perform the following
functions:
| • | Provide a mechanical load |
| • | Prevent overshoot of the needle |
| • | Return the indicator to zero when the road speed is zero |
The electric speedometer does not have a speedometer cable. The source
of the speed information is a small permanent magnet called the Vehicle Speed
Sensor (VSS), mounted on the transaxle.
The shaft of the VSS fits into a pinion gear on the transaxle in the
same manner as the speedometer cable of a mechanical speedometer system. When
the transmission output rotates, the VSS rotates and turns the permanent magnet
near a coil within the VSS. This action generates a signal using a frequency
that is proportional to the speed of the vehicle. The signal is converted
into a magnetic field at the speedometer causing the pointer to move. The
relative force of the frequency determines the position of the speedometer
pointer.
The odometer on the instrument cluster consists of numbered wheels that
are electrically driven by the speedometer. The wheels are geared so that
when any one wheel completes a revolution, the wheel immediately to the left
will rotate a tenth of a revolution.
