Mechanical System Test

MECHANICAL SYSTEM TEST [FS5A-EL]

Line Pressure Test Preparation

1. Set the oil cooler out of the way to prevent interference with the SST.
a. Disconnect the oil cooler from the transaxle. Removal and Replacement
NOTE:
- Do not disconnect the oil hose and water hose from the oil cooler and transaxle to perform the line pressure test.

b. Suspend the oil cooler using rope to secure the disconnected oil cooler.






CAUTION:
- To prevent damage to the parts, do not pull the oil hose and water hose excessively.
- To prevent damage to the parts, do not twist the oil hose and water hose.
- To prevent part damage, do not allow parts to interfere with the cooling fan.

Mechanical System Test Preparation

1. Inspect the engine coolant level. Engine Coolant Level Inspection

2. Inspect the engine oil level. Testing and Inspection

3. Inspect the ATF level. Testing and Inspection

4. Inspect the ignition timing. Service and Repair

5. Inspect the idle speed. Service and Repair

6. Verify that no DTCs are stored.

Line Pressure Test

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.

1. Remove the aerodynamic under cover. Service and Repair

2. Prepare for the line pressure test.

3. Prepare for the mechanical system test.

4. Measure the line pressure while idling in the D position.
a. Remove the pressure detection square head plug.






WARNING:
- Do not remove the square head plug when the ATF temperature is high. Otherwise, ATF could overflow and cause severe burns or serious injury. Remove the square head plug when the transaxle and ATF temperature are low.

b. Install the SSTs (49 D019 910, 49 D019 911, 49 D019 913, 49 D019 909, 49 D019 908) to the pressure detection port as shown in the figure.






c. Apply the parking brake firmly and set the wheel blocks to the front and rear wheels.

d. Start the engine.

e. Warm up the engine until the ATF temperature is 60-70 °C {140-158 °F}.

f. Shift the selector lever to the D position.

g. Measure the line pressure while idling.

5. Measure the line pressure while idling in each position in the same procedure.

6. Stop the engine.

7. Measure the line pressure while stalling in the D position.
a. Replace the oil pressure gauge of the SST as follows:

- Remove the SST (49 D019 908) and replace the SST (49 D019 907).





b. Start the engine.

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

d. Shift the selector lever to the D position.

CAUTION:
- To prevent damage to the transaxle, measure the line pressure (Step (5)-(6)) within 5 s while stalling.

e. Depress the accelerator pedal with the right foot all the way down slowly.

f. Read the line pressure quickly while stalling, and remove the right foot from the accelerator pedal.

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

8. Measure the line pressure while stalling for each position in the same procedure.

- If there is any malfunction, one of the following malfunctions may have occurred:





Line pressure





9. Stop the engine.

10. Remove the SSTs.

WARNING:
- If the SSTs is removed when the ATF temperature is high, ATF could overflow and cause severe burns or serious injury. Remove the SSTs when the transaxle and ATF temperature is low.

11. Install a new square head plug.
NOTE:
- Do not reuse the square head plug because a sealant coating is applied.

Tightening torque
- 5-9 Nm {51-91 kgf-cm, 45-79 in-lbf}

12. Install the oil cooler. Removal and Replacement

13. Install the aerodynamic under cover. Service and Repair

Stall Test

1. Prepare for the mechanical system test.

2. Firmly apply the parking brake and set the wheel blocks to the front and rear wheels.

3. Start the engine.

4. Measure the stall speed in the D position.
a. Strongly depress the brake pedal with the left foot.

b. Shift the selector lever to the D position.

CAUTION:
- To prevent damage to the transaxle, measure the stall speed (Step (5)-(6)) within 5 s.

c. Slowly depress the accelerator pedal with the right foot all the way down.

d. Read the engine speed quickly when the speed is stabilized, and remove the right foot from the accelerator pedal.

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

5. Measure the stall speed in each position in the same procedure.

- If there is any malfunction, one of the following malfunctions may have occurred:





Stall speed





Time Lag Test

1. Prepare for the mechanical system test.

2. Firmly apply the parking brake and set the wheel blocks to the front and rear wheels.

3. Start the engine.

4. Measure the time lag from the N position to the D position.
a. Shift the selector lever from the N to D position with the brake pedal depressed.

b. Measure the time until the shift shock is felt firmly after shifting.

5. Measure the time lag from the N to R position using the same procedure.

- If there is any malfunction, one of the following malfunctions may have occurred:
