NOTE
1. As shown by the “1 symbol, the limit switch within the
actuator will become as shown in the figure at the left if
the. actuator selector is at the fully closed position when
the resistance between terminals No.
1 and No. 2 i
s
measured; for that reason, after checking the polarity of
the tester, the tester’s probe should be connected so that
current flows from the No. 1 terminal to the No. 2
terminal.
2.For terminals No. 8 and 14 indicated by the “2
symbol, it is
necessary to check individual terminal voltages with the
ECU’s harness connector connected and with the ignition
switch ON.
(1) The
No.8 terminal is normal if the diagnostic trouble
code can be confirmed. (Refer to
P.13-361.)
(2) The No. 14 terminal is normal if there is approximately
12V with the auto-cruise control system not functioning
and the overdrive switch switched ON. (Refer to
P. 13-349.)
VEHICLE-SPEED SENSOR INSPECTION
Refer to GROUP
54-Meters and Gauges for checking of
vehicle speed sensor.

CAUTION When

servicing clutch assemblies or com-
ponents for vehicles with SOHC engine
(Up to 1991 models), do NOT create dust
by sanding or by cleaning clutch parts
with a dry brush or with compressed air.
(A water dampened cloth should be used).
The clutch disc contains “Asbestos Fibers”
which can become airborne if dust is
created during service operations. Breath-
ing dust containing “Asbestos Fibers”
may cause serious bodily harm.
