MECHANICAL SYSTEM TESTS
1. PERFORM 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:

Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature 50
to 80
C (122 to 176
F).

Do not continuously run this test for longer than 10 seconds.

To ensure safety, do 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 an Intelligent Tester II 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.
(7) Quickly read the stall speed at this time.
Stall speed: 2,400
150 rpm
(8) Do the same test in the R position.
Stall speed: 2,400
150 rpm
Evaluation:
ProblemPossible cause
(a) Stall engine speed is low in D and R positions

Engine power output may be insufficient

Stator one–way clutch not operating properly
HINT: If the value is less than the specified value by 600 rpm or
more, the torque converter could be faulty.
(b) Stall engine speed is high in D position

Line pressure is too low

Forward clutch slipping

One–way clutch No.2 not operating properly
(c) Stall engine speed is high in R position

Line pressure is too low

Reverse clutch slipping

1st and reverse brake slipping
(d) Stall engine speed is high in D and R positions
Line pressure is too low

Improper fluid level

(b) Measure the time lag.
(1) When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag
before the shock can be felt. This is used for checking the condition of the direct clutch, forward
clutch, and 1st and reverse brake.
NOTICE:

Perform the test at the normal operating ATF temperature 50 to 80
C (122 to 176
F).

Be sure to allow 1 minute interval between tests.

Perform the test three times, and measure the time lags. Calculate the average value of the three
time lags.
(2) Connect an Intelligent Tester II to the DLC3.
(3) Fully apply the parking brake.
(4) Start and warm up the engine and check idle speed.
Idle speed: approx. 700 rpm (In N position and A/C OFF)
(5) Shift the lever from N to D position. Using a stop watch, measure the time from when the lever
is shifted until the shock is felt.
Time lag: N → D less than 1.2 seconds
(6) In the same way, measure the time lag for N → R.
Time lag: N → R less than 1.5 seconds
Evaluation (If N → D or N → R time lag is longer than the specified):
ProblemPossible cause
N → D time lag is longer

Line pressure is too low

Forward clutch worn

One–way clutch No.2 not operating properly
N → R time lag is longer

Line pressure is too low

Reverse clutch worn

1st and reverse brake worn

DTC P0998 SHIFT SOLENOID ”F” CONTROL CIRCUIT
LOW (SHIFT SOLENOID VALVE SB)
DTC P0999 SHIFT SOLENOID ”F” CONTROL CIRCUIT HIGH (SHIFT SOLENOID VALVE SB)
CIRCUIT DESCRIPTION
Shift solenoid valve SB controls the 2nd brake (B1) and 1st and reverse brake pressures and performs the
1st and 2nd engine brake control.
Fail safe function:

S shift control prohibition.

On activating the fail–safe function during S shift, the driving mode\
turns to the normal D position.

ECM
MONITOR DESCRIPTION
The ECM commands gear shifts by turning the shift solenoid valves ”ON/OF\
F”. When there is an open or
short circuit in any shift solenoid valve circuit, the ECM detects the problem and illuminates the MIL and
stores the DTC. And the ECM performs the fail–safe function and turns the o\
ther shift solenoid valves in good
condition ”ON/OFF” (In case of an open or short circuit, the ECM stops sen\
ding current to the circuit.)

DTC P0787 SHIFT/TIMING SOLENOID LOW (SHIFT SOLENOID VALVE ST)
DTC P0788 SHIFT/TIMING SOLENOID HIGH (SHIFT SOLENOID VALVE ST)
CIRCUIT DESCRIPTION
The shift solenoid valve ST is used for shifting from the 3rd to 4th gear, and from the 4th to 3rd gear. Actuates
solenoid valves ST and SLT in accordance with the signals from the ECM, and guides this output pr\
essure
directly to 4–3 shift timing valve and 3–4 shift timing valve in order to regulate the line pressure that acts on
the B

DTC P0751 SHIFT SOLENOID ”A” PERFORMANCE
(SHIFT SOLENOID VALVE S1)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor and speed sensor NT to detect the actual gear position
(1st, 2nd, 3rd or 4th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical
problems of the shift solenoid valves and valve body.
DTC No.DTC Detecting ConditionTrouble Area

when driving (2–trip detection logic)

Shift solenoid valve S1 remains open or closed

Valve body is blocked

Shift solenoid valve S1

Automatic transaxle (clutch, brake or gear etc.)

ECM
MONITOR DESCRIPTION
The ECM commands gear shifts by turning the shift solenoid valves ”ON/OFF”. According to the input shaft
revolution, intermediate (counter) shaft revolution and output shaft revolution, the ECM detects the actual
gear position (1st, 2nd, 3rd or 4th gear position). When the gear position commanded by the ECM and the
actual gear position are not same, the ECM illuminates the MIL.
Example:
When either condition (a) or (b) is met, the ECM detects a malfunction.
(a) The ECM commands the 1st gear, but the actual gear is 2nd.
(b) The ECM commands the 2nd gear, but the actual gear is 1st.

DTC P0724 BRAKE SWITCH ”B” CIRCUIT HIGH
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 depressed, this switch sends a signals to the ECM. Then the ECM cancels the op-
eration of the lock–up clutch while braking is in progress.
DTC No.DTC Detecting ConditionTrouble Area

The stop light switch remains ON even when the vehicle is
driven in a GO (30 km/h) and STOP (3 km/h) fashion 10 times.
(2–trip detection logic).
Short in stop light switch signal circuit

Stop light switch

ECM
MONITOR DESCRIPTION
This DTC indicates that the stop light switch remains on. When the stop light switch remains ON during ”stop
and go” driving, the ECM interprets this as a fault in the stop light switch and the MIL comes on and the ECM
stores the DTC. The vehicle must stop (less than 3 km/h (2 mph)) and go (30 km/h (19 mph) or more) ten
times for two driving cycles in order to detect malfunction.
