B INSTALLATION
To install, follow the removal steps in the reverse
order.
SPEEDOMETER (FIG. 8-346)
Fig. 8-346
The speedometer is made up
of the cross coil type
ammeter (movement)
that displays indications, the
stepper
motor that drives and adds up the odometer
and
trip meter, and the driving circuit (printed circuit
board) that makes exchanges between the
pulse sig­
nals and the current.
Also, the vehicle speed sensor, which is incorporated
into the speedometer, is activated
by receiving sig­
nals (vehicle speed) detected by the vehicle speed
sensor
installed to the transmission.
•

(1!] ON-VEHICLE SERVICE
"-"" Check the meter display accuracy and the operation
of the odometer with the speedometer tester.
\f CAUTION:
Inappropriate tire inflation may affect the accu­
racy
of the odometer.
(To
conductthis test, refer to the tester manufac­
turer's instruction manual.)

~ INDIVIDUAL INSPECTION
I t!!.l Remove the speedometer from the meter
assembly and measure the resistance and the
current consumption between each terminal.
(Fig. 8-347)
Replace the speedometer
when the result of
inspection is found abnormal.
