HOW TO PROCEED WITH TROUBLESHOOTING
Troubleshoot in accordance with the procedure on the following pages.

(6) Check for the lock−up mechanism.
Drive in the D position, O/D gear, at a steady speed (lock−up ON) of about 75 km/h (47
mph).
Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
If there is a big jump in engine speed, there is no lock−up.
(b) 2 position test.
Shift into the 2 position and, while driving with the accelerator pedal held constantly at the full throttle
valve opening position, push in one of the pattern selectors and check on the following points.
(1) Check to see that the 1 → 2 up−shift takes place and that the shift point conforms to that shown
on the automatic shift schedule (See page SS−35).
(2) While running in the 2 points and 2nd gear, release the accelerator pedal and check the engine
braking effect.
Evaluation:
ProblemPossible cause
If these is no engine braking effect2nd coast brake is defective
(3) Check for abnormal noises during acceleration and deceleration, and for shock at up−shift and
down−shift.
(c) L position test.
(1) While running in the L position, check to see that there in no up−shift to 2nd gear.
(2) While running in the L position, release the accelerator pedal and check the engine braking ef-
fect.
Evaluation:
ProblemPossible cause
If these is no engine braking effect1st and reverse brake defective
(3) Check for abnormal noises during acceleration and deceleration.
(d) R position test.
Shift into the R position and, while starting at full throttle, check for slipping.
CAUTION:
Before conducting this test ensure that the test area is free from personnel an obstructions.
(e) P position test.
Stop the vehicle on a gradient (more than 5°) and after shifting into the P position, release the parking
brake. Then check to see that the parking lock pawl holds the vehicle in place.

(3) Return the lever 2 notches to the NEUTRAL posi-
tion.
(4) Set the shift lever in the N position.
(5) While holding the lever lightly toward the ”R” posi-
tion side, tighten the shift lever nut.
(i) Adjust the park/neutral position switch.
If the engine will start with the shift selector in any position other
than the N or P position, adjustment is required.
(1) Loosen the park/neutral position switch bolts and
set the shift selector to the N position.
(2) Align the groove and neutral basic line.
(3) Hold in position and tighten the bolts.
Torque: 5.4 N·m(55 kgf·cm,48 in·lbf)
(j) Inspect the idle speed.
Idle speed: 750 ± 50 rpm (In N position and A/C OFF)
8. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:
Do the test at normal operating ATF temperature 50 − 80°C (122 − 176°F).
Do not continuously run this test longer than 5 seconds.
To ensure safety, conduct this test in a wide, clear, level area which provides good traction.
The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect OBD II scan tool or TOYOTA hand−held tester to the DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
Quickly read the stall speed at this time.
Stall speed: 2,400 ± 150 rpm
(7) Do the same test in R position.
Stall speed: 2,400 ± 150 rpm
Evaluation:
ProblemPossible cause
Stall speed low in D and R positions
Engine output may be insufficient
Stator one−way clutch is operating properly
HINT:
If more than 600 rpm below the specified value, the torque converter clutch could
be faulty

Stop Light Switch Circuit
CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling, while driving in lock−up condition, when
brakes are suddenly applied.
When the brake pedal is operated, this switch sends a signal to ECM. Then the ECM cancels of the lock−up
clutch while braking is in progress.

INSPECTION PROCEDURE
1 Check operation of stop light.
CHECK:
Check if the stop lights go on and off normally when the brake pedal is operated and released.

PRE−CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
When the ignition switch is turned ON, check that the ABS
warning light goes on for 3 seconds.
HINT:
If the indicator check result is not normal, proceed to trouble-
shooting for the ABS warning light circuit (See page DI−275).
(b) Check the DTC.
(1) Turn the ignition switch ON.
(2) Disconnect the short pin from the DLC1.
(3) Using SST, connect terminals Tc and E1 of the
DLC1.
SST 09843−18020
(4) Read the DTC from the ABS warning light on the
combination meter.
HINT:
If no code appears, inspect the diagnostic circuit or ABS
warning light circuit (See page DI−278 or DI−275).
As an example, the blinking patterns for normal code and
codes 11 and 21 are shown in the illustration.
(5) Codes are explained in the code table on page
DI−242.
(6) After completing the check, disconnect terminals Tc
and E1, and turn off the display.
If 2 or more malfunctions are indicated at the same time, the
lowest numbered DTC will be displayed 1st.
