Mechanical System Test

MECHANICAL SYSTEM TEST [FS5A-EL]

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. Engine Coolant Level Inspection

3. Inspect the engine oil. Testing and Inspection

4. Inspect the ATF. Procedures

5. Inspect the idle speed. Service and Repair

6. Inspect the ignition timing. Service and Repair

7. Verify that no DTCs recorded. Reading and Clearing Diagnostic Trouble Codes

Line Pressure Test

1. Perform "Mechanical System Test Preparation". (See 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.

NOTE:
- Use a suitable oil pressure gauge that corresponds to the line pressure because the maximum scale value differs depending on the oil pressure gauge.

2. Perform the line pressure test with the engine idle at the D position.
a. Remove the square-head plug from the line pressure inspection port.






b. Connect the SSTs as following:

- When using the oil pressure gauge set (49 0378 400C), connect the SSTs (49 H019 002, 49 0378 400C, 49 B019 901B) to the line pressure inspection port as shown in the figure.
- When using the oil pressure gauge set (49 D019 9A2), connect the SSTs (49 D019 910, 49 D019 911, 49 D019 913, 49 D019 909, 49 D019 908) to the line pressure inspection port as shown in the figure.





c. Start the engine.

d. Warm-up the transaxle until the ATF temperature reaches 60-70 °C {140-158 °F}.

e. Shift the selector lever to the D position.

f. Read the line pressure with the engine idle.

3. Perform the line pressure test at the engine idle at each position in the same manner.

4. Stop the engine.

5. Perform the line pressure test with the engine stall at the D position.
a. Replace the oil pressure gauge as following:

- When using the oil pressure gauge set (49 0378 400C), replace the SST (49 B019 901B) with SST (49 B019 902A).
- When using the oil pressure gauge set (49 D019 9A2), replace the SST (49 D019 908) with SST (49 D019 907).





b. Start the engine.

c. Firmly depress the brake pedal with the left foot.

d. Shift the selector lever to the D position.

CAUTION:
- If the accelerator pedal is pressed for longer than 5 s while the brake pedal is pressed, the transaxle could be damaged. Therefore, perform Steps (5)-(6) within 5 s.

e. Gradually depress the accelerator pedal with the right foot.

f. When the engine speed no longer increases, quickly read the line pressure and release the accelerator pedal.

g. Shift the selector lever to the N position and let the engine idle for 1 min or more to cool the ATF.

6. Perform the line pressure test with the engine stall at each position in the same manner.

- If there is any malfunction, inspect the following "possible cause" according to the condition.

7. Stop the engine.

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

8. Remove the SSTs.
NOTE:
- Do not reuse the square-head plug because it is coated.

9. Install a new square-head plug in the inspection port.

Tightening torque
- 4.8-9.8 Nm {49-99 kgf-cm, 43-86 in-lbf}

Stall Test

1. Perform "Mechanical System Test Preparation". (See Mechanical System Test Preparation.)

2. Start the engine.

3. Perform the stall test at the D position.
a. Firmly depress the brake pedal with the left foot.

b. Shift the selector lever to the D position.

CAUTION:
- If the accelerator pedal is pressed for longer than 5 s while the brake pedal is pressed, the transaxle could be damaged. Therefore, perform Steps (3)-(4) within 5 s.

c. Gently depress the accelerator pedal with the right foot.

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

e. Shift the selector lever to the N position and let the engine idle for 1 min or more to cool the ATF.

4. Perform the stall test at each position in the same manner.

- If there is any malfunction, inspect the following "possible cause" according to the condition.





Stall Speed





Time Lag Test

1. Perform "Mechanical System Test Preparation". (See Mechanical System Test Preparation.)

2. Start the engine.

3. Perform the time lag test when shifting the selector lever from the N position to the D position.
a. Shift the selector lever from the N position to the D position while the brake pedal is depressed.

b. Measure the time it takes from shifting until shock is felt when shifting the selector lever from the N position to the D position.

4. Perform the time lag test when shifting the selector lever from the N position to the R position in the same manner.

- If there is any malfunction, inspect the following "possible cause" according to the condition.
