light TOYOTA CAMRY V20 1986 Service Information

3. INSPECT EACH UP±SHIFT POSITION
(a) Warm up the engine.
Coolant temperature: 176
°F (80°)
(b) Turn the O/D switch to ºONº.
(c) Place the pattern select switch in ºNormalº and the shift
lever into the D range.
(d) During a road test (above 10 km/h or 6 mph) check that volt-
age at the Tt terminal is as indicated below for each up±
shift position.
If the voltage rises from 0V to 7V in the sequence shown,
the control system is okay.
The chart on the left shows the voltmeter reading and cor-
responding gears.
HINT: Determine the gear position by a fight shock or
change in engine rpm when shifting. The lock±up clutch will
turn ON only infrequently during normal 2nd and 3rd gear
operation. To trigger this action, press the accelerator pedal
to 50% or more of its stroke. At less than 50%, the voltage
may change in the sequence 2v ± 4V ± 6V ± 7V. 2. INSPECT BRAKE SIGNAL
(a) Depress the accelerator pedal until the Tt terminal indi-
cates 8V.
(b) Depress the brake pedal and check the voltage read-
ing from the Tt terminal.
Brake pedal depressed ...... 0V
Brake pedal released . . . . . . . . 8V
If not as indicated, there is a malfunction in either the
stop light switch or circuit.
INSPECTION OF ECT OR Tt TERMINAL
VOLTAGE
1. INSPECT THROTTLE POSITION SENSOR SIGNAL
(a) Turn the ignition switch to ON. Do not start the engine.
(b) Connect a voltmeter to terminals Tt and E1.
(c)while slowly depressing the accelerator pedal, check
that Tt terminal voltage rises in sequence.
If the voltage does not change in proportion to the
throttle opening angle, there is a malfunction in the
throttle position sensor or circuit.

INSTALLATION OF THROTTLE CABLE
1. INSTALL CABLE INTO TRANSMISSION CASE
2. INSTALL VALVE BODY
3. IF THROTTLE CABLE IS NEW, STAKE STOPPER OR
PAINT MARK ON INNER CABLE

(a) Bend the cable so there is a radius of about 200 mm(7.87 in.).
(b) Pull the inner cable lightly until a slight resistance is felt, and hold
it.
(e) Stake the stopper, 0.8 ± 1.5 mm (0.031 ± 0.059 in.)
from the end of outer cable.

47. REMOVE FIRST AND REVERSE BRAKE PISTON
(a) Remove the piston return spring.
Place SST, and compress the return spring evenly by
tightening the bolt gradually.
SST 09350±32014 (09351±32040)
(b) Apply compressed air into the passage of the case
to remove the piston.
HINT: Hold the piston so it is not slanted and blow
with the gun slightly away from the oil hole. wUsing snap ring pliers, remove the snap ring.
wRemove SST.
wRemove the return spring from the case. (e) Remove the overdrive clutch apply gasket and over-
drive brake apply gasket.
(c) If the piston does not pop out with compressed air,
use needle±nose pliers to remove it.

INSPECTION OF OVERDRIVE BRAKE
INSPECT DISCS, PLATES AND FLANGE
Check if the sliding surfaces of the discs, plates and
flange are worn or burnt. If necessary, replace them.
HINT:
wIf the lining of the disc is exfoliated or discolored, or
even a part of the printed numbers are defaced, re-
place all discs.
wBefore assembling new discs, soak them in ATF for
at least fifteen minutes.
