On-Vehicle Inspection

MECHANICAL SYSTEM TEST [LJ4A-EL]
Mechanical System Test Preparation
1. Apply the parking brake and use wheel chocks at the front and rear of the wheels.
2. Inspect the engine coolant.
3. Inspect the engine oil.
4. Inspect the ATF levels.
5. Inspect the ignition timing.
6. Inspect the idle speed.

Line Pressure Test
1. Perform 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.








Specified line pressure

2. Connect the SSTs (49 B019 901, 49 B019 903, and 49 H019 002) to the line pressure inspection port.
3. Shift the selector lever to D range and read the line pressure at idle.
4. Connect the SST (49 B019 902) to the line pressure inspection port.

Caution If the accelerator pedal is pressed for longer than 5 seconds while the brake pedal is pressed, the transaxle could be damaged. Therefore, do steps 5 and 6 within 5 seconds of each other.

5. Firmly depress the brake pedal with the left foot, and gently depress the accelerator pedal to floor with the right.
6. When the engine speed no longer increases, quickly read the engine speed and release the accelerator.
7. Shift the selector to the N position and let the engine idle for 1 minute or more to cool the ATF.
8. Read the line pressure at idle and at the engine stall speed for remaining ranges in the same manner.

Warning Removing the SST when the ATF is hot can be dangerous. Hot ATF can come out of the opening and badly burn you. Before removing the SST, allow the ATF to cool.

9. Remove the SST.
10. Install a new square-head plug in the inspection port.
Tightening torque
5.0 - 9.8 Nm (50 - 100 kgf.cm, 44 - 86 inch lbs.)





Evaluation of line pressure test

Stall Test
1. Perform mechanical system test preparation.
2. 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, do steps 3 and 4 within 5 seconds of each other.

3. Firmly depress the brake pedal with the left foot, and gently depress the accelerator pedal to floor with the right.
4. When the engine speed no longer increases, quickly read the engine speed and release the accelerator pedal.
5. Shift the selector to the N position and let the engine idle for 1 minute or more to cool the ATF.
6. Perform stall tests for the remaining ranges in the same manner.
1. S range
2. L range
3. R position
Engine stall speed
D, S, L range: 2,150 - 2,450 rpm
R position: 1,950 - 2,250 rpm





Evaluation of stall test

Time Lag Test
1. Perform mechanical system test preparation.
2. Shift the selector lever from the N position to D range.
3. Use a stopwatch to measure the time it takes from shifting until engagement is felt.
4. Shift the selector lever to the N position and run the engine at idle speed for at least 1 minute.
5. Do the time lag test for the following shifts in the same manner. Make three measurements for each test and average the results.
6. Perform the test for the following shifts in the same manner.
1. N position - D range (Non-HOLD mode)
2. N position - D range (HOLD mode)
3. N position - R position
Time lag
N position - D range...approximately 0.9 second
N position - R position...approximately 1.1 second
