AUTOMATIC TRANSAXLE [AW6A-EL, AW6AX-EL] 05-17–5 05-17 17. Verify that the line pressure and LPS PID current values change according to the following graph by changing the shift throttle opening angle when shifting to the D range and R position with the engine running. — The line pressure standard other than when the engine is idling cannot be determined because the maximum line pressure for this automatic transaxle is controlled by vehicle conditions. 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. 18. Remove the SSTs. Tightening torque 5.9— 8.8 N·m {61— 89 kgf·cm, 53— 77 in·lbf} Line pressure test evaluation Stall Test 1. Perform mechanical system test preparation. (See 05-17-3 Mechanical System Test Preparation.) Caution • If the accelerator pedal is depressed for more than 5 s while the brake pedal is depressed, the transaxle could be damaged. Therefore, perform Steps 5 and 6 within 5 s. • Perform the test at least 3 times and calculate the average. 5. Gently depress the accelerator pedal with the right foot. 1,500 2,000 500 300 1,000 300 THROTTLE OPENING STALL IDLE D RANGE R POSITION LINE PRESSURE 2 ,psi}) LINE PRESSURE LINE PRESSURE CURRENT acxuuw00000481 Condition Possible cause Lower than specification in D range and • Line pressure control solenoid malfunction • Primary regulator valve malfunction • Oil pump malfunction • Oil leaking from D range or R position hydraulic circuit Constant pressure without fluctuation in • Line pressure control solenoid malfunction • Control valve body internal malfunction Current to throttle does not change in D • TCM internal malfunction • Connector malfunction Hydraulic pressure in R position is not • Primary regulator valve malfunction 1871-1U-06B(05-17).fm 5 ページ 2006年3月15日 水曜日 午前11時20分 |
