Stall Test

WARNING: This page is about a different variant/trim than selected.
  1. Perform the "Mechanical System Test Preparation". (See MECHANICAL SYSTEM TEST PREPARATION .)
  2. Start the engine.
  3. Perform the stall test at D position.
    1. Firmly depress the brake pedal with the left foot.
    2. 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.
  4. 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.
  5. Gently depress the accelerator pedal with the right foot.
  6. When the engine speed no longer increases, quickly read the engine speed and release the accelerator pedal.
  7. Shift the selector lever to the N position and idle the engine for 1 min  or more to cool the ATF.
  8. 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.
