DTCP0724BRAKE SWITCH ºBº CIRCUIT HIGH
CIRCUIT DESCRIPTION
This STP signal is used to detect that the brakes have been applied. The STP\
signal voltage is the same
as the one supplied to the stop lights.
The STP signal is used mainly to control the fuel cut±off engine speed (The fuel cut±off engine speed is re-
duced slightly when the vehicle is braking).

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.
1 CHECK OPERATION OF STOP LIGHT
(a) Check if the stop lights go on and off normally when the brake pedal is operated and released.

2 READ VALUE OF HAND±HELD TESTER(STOP LIGHT SWITCH)
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand±held tester main switch \
ON.
(c) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / STOP LIGHT SWº and read its value displayed on the hand±held tester.

(8) Simulate the conditions of the malfunction de-
scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTCs, etc.
(9) After simulating the malfunction conditions, use the
hand±held tester diagnosis selector to check the
DTCs and freeze frame data, etc.
HINT:
Take care not to turn the ignition switch OFF, as turning it off
switches the diagnosis system from Check mode to Normal
mode, which all DTCs etc. are erased.
(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
(1) When using the hand±held tester:
The following operation will erase the DTC and
freeze frame data. Operate the hand±held tester to
erase the codes.
(2) When not using the hand±held tester:
Remove the EFI fuse from engine room J/B for 60
seconds or more.
4. DATA LIST
HINT:
According to the DATA LIST displayed by the hand±held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
of the methods to shorten the work time.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) According to the display on tester, read the ºDATA LISTº.

7.ROAD TEST
NOTICE:
Conduct the test at normal operating ATF temperature 50 to 80
C (122 to 176
F).
(a)D range test Shift into the D range and fully depress the accelerator pedal and check\
the following points:
(1)Check up±shift operation.Check that 1  2, 2  3 and 3  O/D up±shift take place, and that the shift points conform to
the automatic shift schedule (See page 03±45).
HINT:
O/D Gear Up±shift Prohibition Control

Coolant temp. is 60 C (140 F) or less and vehicle speed is 70 km/h (43 mph) or less.

ATF temp. is 10 C (50 
) or less.
O/D and 3rd Gear Lock±up Prohibition Control

Brake pedal is depressed.

Accelerator pedal is released.

ATF temp. is 10 C (50 
) or less.

Coolant temp. is 60 C (140 F) or less.
When the 2nd start switch is on, there is no 1 2 up±shift and 2 1 down±shift.
(2)Check for shift shock and slip. Check for shock and slip at the 1  2, 2  3 and 3  O/D up±shift.
(3)Check for abnormal noises and vibration. Run in D range lock±up or O/D gear and check for abnormal noise and v\
ibration.
HINT:
The check for the cause of abnormal noise and vibration must be done ver\
y thoroughly as it could also be
sure to loss of balance in the differential, torque converter, etc. (4)Check kick±down operation.While running in the D range, 2nd, 3rd and O/D gears, check to see that the p\
ossible kick±down
vehicle speed limits for 2  1, 3  2 and O/D  3 kick±downs conform to those indicated in the
automatic shift schedule (See page 03±45).
(5) Check for abnormal shock and slip at kick±down.
(6) Check the lock±up mechanism.

Drive in D range O/D gear, at a steady speed (lock±up ON) of about 70 km/h (43 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) S range test Shift to the S range, depress the accelerator pedal and check the follow\
ing points:
Shift operations.

Shifting the shift lever to º+º or º±º changes the shift \
range on the combination meter.
HINT:
Manual shift prohibition control is performed when:

Down±shifting causes engine overrun.

Down±shifting is required continuously. (Down±shifting to 1st gear may not be performed.)
(c) R range test Shift into the R range and fully depress the accelerator pedal and check\
for slipping.
CAUTION:
Before conducting this test, ensure that the test area is free from peop\
le and obstruction.
(d) P range test Stop the vehicle on a grade (more than 5 ) and after shifting into the P range, release the parking
brake. Then, check to see that the parking lock pawl holds the vehicle in plac\
e.

ROAD TEST
1. PROBLEM SYMPTOM CONFIRMATION
(a) Based on the result of the customer problem analysis, try to reproduce the symptoms. If the problem
is that the transaxle does not shift up, shift down, or the shift point is too high or too low, conduct the
following road test referring to the automatic shift schedule and simulate the problem symptoms.
2. ROAD TEST
NOTICE:
Perform the test at the ATF (Automatic Transmission Fluid) temperature 50 to 80 ËšC( 122 to 176 ËšF) in
the normal operation.
(a) D position test: Shift into the D position and fully depress the accelerator pedal and check the following points.
(1 ) Check up −shift operation.
Check that 1
2, 2
3, 3
4 and 4
5th up −shifts take place, and that the shift points conform
to the automatic shift schedule (see page 03 −33).
HINT:
5th Gear Up −shift Prohibition Control
S ATF temperature is −2 ˚C (28 ˚F ) or less.
5th and 4th Gear Lock −up Prohibition Control
S Brake pedal is depressed.
S Accelerator pedal is released.
S Engine coolant temperature is 60 ËšC( 140 ËšF) or less.
(2) Check for shift shock and slip. Check for shock and slip at the 1
2, 2
3, 3
4 and 4
5th up −shifts.
(3) Check for abnormal noise and vibration. Check for abnormal noise and vibration when up −shifting from 1
2, 2
3, 3
4 and 4
5
while driving with the shift lever in the D position, and check while driving in the lock −up condition.
HINT:
The check for the cause of abnormal noise and vibration must be done thoroughly as it could also be due
to loss of balance in the differential, torque converter clutch, etc.
(4) Check kick −down operation.
Check vehicle speeds when the 2nd to 1st, 3rd to 2nd, 4th to 3rd, and 5th to 4th kick −downs take
place while driving with the shift lever in the D position. Confirm that each speed is within the
applicable vehicle speed range indicated in the automatic shift schedule (see page 03 −33).
(5) Check for abnormal shock and slip at kick −down.
(6) Check the lock −up mechanism.
SDrive in D position (5th gear), at a steady speed (lock −up ON).
SLightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
HINT:
SThere is no lock −up function in the 1st, 2nd and 3rd gear.
S4th lock −up operates while uphill −downhill control is active in the D position.
SIf there is a big jump in engine speed, there is no lock −up.
