Mechanical System Test [FS5A-EL Transmission]
MECHANICAL SYSTEM TEST [FS5A-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. Service Precautions Engine Coolant Protection Inspection
3. Inspect the engine oil. Engine Coolant Level Inspection
4. Inspect the ATF level. Procedures
5. Inspect the idle speed. Testing and Inspection
6. Inspect the ignition timing. Testing and Inspection
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.
2. Connect the SSTs (49 H019 002 and, 49 0378 400C) to the line pressure inspection port and replace the gauge of the SST (49 0378 400C) with the SST (49 B019 901B).
3. Start the engine and warm it up until the ATF reaches 60-70 °C {140-158 °F}.
4. Shift the selector lever to the D range.
5. Read the line pressure while the engine is idling for the D range.
6. Read the line pressure while the engine is idling for the R position and M (1GR, 2GR) range 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 the D range.
CAUTION:
- If the accelerator pedal is pressed for more than 5 s while the brake pedal is pressed, the transaxle could be damaged. Therefore, perform Steps 11 and 12 within 5 s.
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 the N position and idle the engine for 1 minute or more to cool the ATF.
14. Read the line pressure at the engine stall speed for the M (1GR, 2GR) range and R position in the same manner as in Steps 9-13. Line pressure
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.
15. Remove the SSTs.
16. Install a new square head plug in the inspection port.
Tightening torque
- 4.8-9.8 Nm {49-99 kgf-cm, 43-85 in-lbf}
Evaluation of line pressure test
Condition/Possible Cause:
Stall Test
1. Perform mechanical system test preparation.
2. Start the engine and shift the selector lever to R position.
CAUTION:
- Do not maintain WOT in any position/range for more than 5 seconds, or transaxle damage will occur.
3. Firmly depress the brake pedal with the left foot, and depress the accelerator pedal to floor (WOT) 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 lever to N position and let the engine idle for 1 minute or more to cool the ATF.
6. Perform stall tests of D, M (1GR, 2GR) ranges in the same manner.
7. Turn off the engine. Engine stall speed
Evaluation of stall test
Condition/Possible Cause:
Time Lag Test
1. Perform mechanical system test preparation.
2. Start the engine and warm up the engine until the ATF temperature reaches 60-70 °C {141- 158 °F}.
3. Shift the selector lever from N position to D range.
4. Use a stopwatch to measure the time it takes from shifting until engagement is felt. Take 3 measurements for each test and average the results using the following formula.
5. Perform the test for the following shifts in the same manner.
- N position->R position
Time lag
Evaluation of time lag test
Condition/Possible Cause:
