SPEEDOMETER/TACHOMETER

GENERAL

See

Figure 2-6

. The speedometer on XL and tachometer on

XR consists of a warning display and four status lamps. The
lamps include: check engine, low fuel, battery, and security.

Trip Odometer Reset Switch

Figure 2-7

. Pressing the trip odometer reset switch provides

the following capabilities:

•

Change the odometer display between mileage, trip A and
trip B values (press and immediately release).

•

Reset an individual trip odometer (press and hold 2-3
seconds).

•

Gain access to the diagnostic mode and clear DTCs. See

2.3 ODOMETER SELF-DIAGNOSTICS

.

•

Display odometer while ignition switch is OFF. Press and
hold trip odometer reset switch while ignition switch is OFF
and odometer mileage will be displayed.

•

On models with dual scale speedometers, toggle between
miles/kilometers on odometer and trip odometer display.
To toggle display, turn ignition switch ON. Press and hold
trip odometer reset switch while odometer is displayed.
Release switch when change is noted. (If trip odometer
reset switch is held while trip odometer is displayed, trip
odometer will reset).

SPEEDOMETER THEORY OF OPERATION

The speedometer circuit consists of a Vehicle Speed Sensor
(VSS), the ECM, the trip odometer reset switch and the
speedometer. The VSS is mounted on the rear of the engine
crankcase behind the starter motor assembly. The sensor cir-
cuitry is that of a Hall-effect sensor triggered by the gear teeth
of 5th gear on the transmission mainshaft.

The output from the sensor is a series of pulses that are inter-
preted by the ECM circuitry, converted into serial data then
sent to the speedometer. The vehicle speed serial data is also
transmitted to the TSM/TSSM/HFSM for turn signal cancella-
tion.

ODOMETER THEORY OF OPERATION

The odometer mileage is permanently stored and will not be
lost when electrical power is turned off or disconnected. The
trip odometer reset switch allows switching between the odo-
meter, trip odometer A and trip odometer B displays.

To zero the trip odometer, have the desired trip odometer dis-
play visible and press and hold the trip odometer reset switch.
The trip odometer mileage will be displayed for 2-3 seconds
and then the trip mileage will return to zero miles.

The odometer can display six numbers to indicate a maximum
of 999999 miles/kilometers. The trip odometers can display six
numbers with a tenth of a mile accuracy for a maximum of
99999.9 miles/kilometers.

TACHOMETER THEORY OF OPERATION

See

Figure 2-8

. The tachometer receives serial data from the

ECM. The tachometer interprets the serial data and converts
it into tachometer needle movement.

NOTE

Indicator lamps in the tachometer face may illuminate during
a "WOW" test, even though they do not function during normal
vehicle operation.
