Stall Test: Notes
- Perform the "Mechanical System Test Preparation". (See MECHANICAL SYSTEM TEST PREPARATION .)
- Start the engine.
- Perform the stall test at D position.
- Firmly depress the brake pedal with the left foot.
- Shift the selector lever to D position.CAUTION:
- If the accelerator pedal is pressed for longer than 5 s while the brake pedal is pressed, the transaxle could be damaged. Therefore, perform Steps (3)-(4) within 5 s.
- Shift the selector lever to the D position.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.
- Gently depress the accelerator pedal with the right foot.
- When the engine speed no longer increases, quickly read the engine speed and release the accelerator pedal.
- Shift the selector lever to the N position and idle the engine for 1 min or more to cool the ATF.
- Perform a stall test of the R position in the same manner.
- If there is any malfunction, inspect the following "Possible Cause" according to the condition.
SYMPTOM CHARTCondition Possible cause Above specification In D position - Low line pressure (Line pressure control solenoid malfunction, primary regulator valve malfunction)
- Control valve body component malfunction (shift solenoid C hydraulic pressure system)
- C1 clutch slipping
- One-way clutch malfunction
In R position - Low line pressure (Line pressure control solenoid malfunction, primary regulator valve malfunction)
- Control valve body component malfunction (shift solenoid E hydraulic pressure system)
- C3 clutch malfunction (slipping)
- B2 brake malfunction (slipping)
In R, D positions - Low line pressure (Line pressure control solenoid malfunction, primary regulator valve malfunction)
- Oil pump malfunction
- Oil strainer clogging
Below specification - Engine lack of power
- Torque converter one-way clutch slipping
