1986 TOYOTA CAMRY V20 stop start

5. P RANGE TEST
Stop the vehicle on a gradient (more than 51 and after
shifting into the P range, release the parking brake.
Then check to see that the parking lock pawl holds the
vehicle in place.(b) While running in the L range, release the acceler-
ator pedal and check the engine braking effect.
EVALUATION
If there is no engine braking effect:
wFirst and reverse brake is defective 3. L RANGE. TEST
(a) While running in the L range, check to see that there
is no up±shift to 2nd gear.
4. R RANGE TEST
Shift into the R range and, while starting at full throttle,
check for slipping.(c) Check for abnormal noise during acceleration and
deceleration.

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
HINT: New cable do not have a cable stopper staked.
(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.
4. CONNECT THROTTLE CABLE TO ENGINE
5. ADJUST THROTTLE CABLE (See page AT±201)
6. INSTALL AND ADJUST NEUTRAL START SWITCH
7. TEST DRIVE VEHICLE

REMOVAL OF THROTTLE CABLE
1. DISCONNECT THROTTLE CABLE FROM ENGINE
2. REMOVE NEUTRAL START SWITCH
3. REMOVE VALVE BODY
4. REMOVE THROTTLE CABLE

ON±VEHICLE INSPECTION
INSPECT SLIDING ROOF GLASS ALIGNMENT
(a) Start the engine and check the operation time of the
sun roof.
Operation time: Approx. 5 secs.
(b) Check for abnormal noise or binding during opera-
tion.
(e) With the sun roof fully closed, check for water leak-
age.
(d) Check for a difference in level between the sliding
roof glass and roof panel.
Front side: 1.9 + 2.0 mm (0.075 +0.079 in.)
±1.0 ±0.039
Rear side: 1.9 + 2.0 mm (0.075 +0.079 in.)
±1.0 ±0.039
If the sliding roof does not operate:
(a) Remove the control switch cover.
(b) Using a special crank±shaped screwdriver, remove
the large screw inside.
NOTICE: Be careful not to lose the spring washer or
shim.
(e) Manually operate the sun roof by inserting a special
crank±shaped screwdriver into the hole and turning
the drive shaft.
ADJUSTMENT OF SLIDING ROOF
1. REMOVE INNER PANEL SIDE GARNISH
Before making adjustments, remove the inner panel side
garnish.
HINT: After adjustment, reinstall the inner panel side gar-
nish.
2. TO ADJUST LEVEL DIFFERENCE
Adjust by increasing or decreasing the number of shims.
HINT: If the front of the sliding roof is high, even without a
shoe shim, chek to see if the front shoes are in contact with
the stoppers.
3. TO ADJUST FORWARD OR REARWARD
Adjust by loosening the sliding roof installation bolts, and
move the sliding roof front shoe forward and rearward.

minal 7 and negative (±) lead to terminal 10.
(b) Check that there is battery voltage with light control
switch is turned on.
If operation is not as specified, replace the relay.If continuity is not as specified, replace the relay.
2. INSPECT DAYTIME RUNNING LIGHT RELAY
(Relay Circuit)
Disconnect the connector from the relay and inspect the
connector on the wire harness side as shown in the chart.
