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 level. (See COOLING SYSTEM SERVICE WARNINGS [MZI-3.7] .) (See

ENGINE COOLANT LEVEL INSPECTION [MZI-3.7] .)

3. Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION [MZI-3.7] .)

4. Inspect the ATF level. (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [AW6A-EL,

AW6AX-EL].)

5. Inspect the idle speed. (See ENGINE TUNE-UP [MZI-3.7] .)

6. Inspect the ignition timing. (See ENGINE TUNE-UP [MZI-3.7] .)

LINE PRESSURE TEST

1. Perform mechanical system test preparation. (See MECHANICAL SYSTEM TEST PREPARATION.)

2. Connect the SSTs (49 HD64 406A 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 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. Connect the M-MDS to the DLC-2.

9. Measure the LPS PID value.

10. Start the engine.

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

12. Shift the selector lever to the D range.

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

CAUTION:



Perform the test at least 3 times and calculate the average.

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 14 and 15 within 5 s.
