MECHANICAL SYSTEM TEST[AW6A-EL, AW6AX-EL]

id051723802100

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 01-12-2 COOLING SYSTEM SERVICE WARNINGS[L3 WITH TC].) (See

01-12-3 ENGINE COOLANT LEVEL INSPECTION[L3 WITH TC].)

3. Inspect the engine oil level. (See 01-11-3 ENGINE OIL LEVEL INSPECTION[L3 WITH TC].)
4. Inspect the ATF level. (See 05-17-10 AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION[AW6A-EL,

AW6AX-EL].)

5. Inspect the idle speed. (See 01-10-35 ENGINE TUNE-UP[L3 WITH TC].)
6. Inspect the ignition timing. (See 01-10-35 ENGINE TUNE-UP[L3 WITH TC].)

Line Pressure Test

1. Perform mechanical system test preparation. (See05-17-3 Mechanical System Test Preparation.)
2. Remove the harness bracket.

Warning

• Removing the test plug when the ATF is

hot can be dangerous. Hot ATF can come
out of the opening and badly burn you.
Before removing the test plug, allow the
ATF to cool.

3. 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).

4. Start the engine and warm it up until the ATF reaches 60— 70

°C {140— 158 °F}.

5. Shift the selector lever to the D range.

Caution

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

6. Read the line pressure while the engine is idling for the D range.
7. 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.

Line pressure

8. Stop the engine, then replace the SST (49 B019 901B) with the gauge of the SST (49 0378 400C).
9. Connect the M-MDS to the DLC-2.

10. Measure the LPS PID value.
11. Start the engine.
12. Firmly depress the brake pedal with the left foot.
13. 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 13
and 14 within 5 s.

14. Gradually depress the accelerator pedal with the

right foot.

15. When the engine speed no longer increases, quickly read the line pressure and release the accelerator pedal.
16. Shift the selector lever to the N position and idle the engine for 1 min or more to cool the ATF.
