Mechanical System Test [FS5A-EL]

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.
3. Inspect the engine oil.
4. Inspect the ATF levels.
5. Inspect the idle speed.
6. Inspect the ignition timing.

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 0378 400C, 49 B01 9 901 B and 49 H019 002.) to the line pressure inspection port.
3. Start the engine and shift the selector lever to D range and read the line pressure at idle.

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.

4. Turn the engine off and remove the SST (49 B01 9 901 B), and replace the gauge part of the SST (49 0378 400C).

Caution:
^ Do not maintain WOT in any position/range for more than 5 seconds, or transaxle damage will occur.

5. Start the engine and firmly depress the brake pedal with the left foot, and then depress the accelerator pedal to floor (WOT) with the right.
6. When the engine speed no longer increases, quickly read the line pressure 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. Read the line pressure at idle and at the engine stall speed for the M (1GR, 2GR) range and R position in the same manner.

Line pressure specification:

9. Shift the selector lever to P position and turn off the engine.

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.

10. Remove the SST.
11. Install a new square head plug in the inspection port.
Tightening torque 4.8 - 9.8 Nm (49 - 99 kgf-cm, 43 - 85 inch lbs.)

Evaluation of line pressure test:

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:

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

Average time lag
N position->D range: 0.4 - 0.7 seconds
N position->R position: 0.4 - 0.7 seconds

Evaluation of time lag test:
