MECHANICAL SYSTEM TEST

A6E561401030W01

Mechanical System Test Preparation

1. Engage the parking brake and use wheel chocks at the front and rear of the wheels.
2. Inspect the engine coolant. (See 

E–3 ENGINE COOLANT LEVEL INSPECTION

.)

3. Inspect the engine oil. (See 

D–4 ENGINE OIL INSPECTION

.)

4. Inspect the ATF levels. (See 

K–12 AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION

.)

5. Inspect the idle speed and ignition timing in P position. (See 

F–8 IDLE SPEED INSPECTION

.)(See 

F–8 

IGNITION TIMING INSPECTION

.)

6. Bring up the engine and transaxle to normal operating temperature.

Line Pressure Test

1. Perform mechanical system test preparation. (See 

K–6 Mechanical System Test Preparation

.)

Warning

• Removing the square-head plug when the ATF is hot can be dangerous. Hot ATF can come out of 

the opening and badly burn you. Before removing the square-head plug, allow the ATF to cool.

2. Connect the SSTs (49 H019 002 and, 49 0378 

400C) to the line pressure inspection port, then 
replace the gauge of the SST (49 0378 400C) 
with the SST (49 B019 901B).

3. Start the engine, then warm up the automatic 

transaxle.

4. Shift the selector lever to D range.
5. Read the line pressure at idle engine speed for 

the D range.

6. Read the line pressure at idle engine speed for 

the D (HOLD), S, S (HOLD), L, L (HOLD) ranges 
and R positions in the same manner as in Steps 
4-5.

7. Stop the engine, then replace the SST (49 B019 

901B) with the gauge of the SST (49 0378 400C).

8. Start the engine.
9. Firmly depress the brake pedal with the left foot.

10. Shift the selector lever to D range position.

Caution

• If the accelerator pedal is pressed for longer than 5 seconds while the brake pedal is pressed, the 

transaxle could be damaged. Therefore, perform Steps 11 and 12 within 5 seconds each.

11. Gradually depress the accelerator pedal with the right foot.
12. When the engine speed no longer increases, quickly read the line pressure and release the accelerator pedal.
13. Shift the selector lever to N position and let the engine idle for 1 minute or more to cool the ATF.
14. Read the line pressure at the engine stall speed for the D, D (HOLD), S, S (HOLD), L, L(HOLD) ranges and R 

position in the same manner as in Steps 9-13.

Warning

• Removing the square-head plug when the ATF is hot can be dangerous. Hot ATF can come out of 

the opening and badly burn you. Before removing the square-head plug, allow the ATF to cool.

Stall Test

1. Perform mechanical system test preparation. (See 

K–6 Mechanical System Test Preparation

.)

2. Start the engine.
3. Firmly depress the brake pedal with the left foot.
4. Shift the selector lever to D range.

Caution

• If the accelerator pedal is pressed for longer than 5 seconds while the brake pedal is pressed, the 

transaxle could be damaged. Therefore, perform Steps 5 and 6 within 5 seconds of each other.

5. Gently depress the accelerator pedal with the right foot.
6. When the engine speed no longer increases, quickly read the speed and release the accelerator pedal. When 

the engine speed no longer increases, quickly read the speed and release the accelerator pedal.

7. Shift the selector lever to N position and let the engine idle for 1 minute or more to cool the ATF.
8. Perform a stall test of D (HOLD), S, S (HOLD), L, L (HOLD) and R range positions in the same manner as in 

Steps 3—7.

9. Turn the ignition switch off.

Time Lag Test

1. Perform mechanical system test preparation. (See 

K–6 Mechanical System Test Preparation

.)

2. Use a stopwatch to measure the time it takes from shifting until shock is felt when shifting the selector lever 

from N position to D range (non-HOLD mode). Take three measurements for each test and take the average 
from the results using the following formula.

Formula:

Average time lag  = (Time 1 + Time 2 + Time 3) / 3

3. Perform the test for the following shifts in the same manner Step 2.
