The air conditioning (A/C) must be turned off. Block all four wheels. Start the engine.

CAUTION:

Apply the parking brake. Press down hard on the brake pedal using your left foot during the test.

Move the gear selector to position . Fully depress the accelerator pedal (AP) for a maximum of 5 seconds  . Read off the maximum engine speed (RPM) and the line pressure. Compare to the table below.

Do not test the stall speed for longer than 5 seconds.

Gear shift position  Line pressure MPa 
D 1.28-1.39
R 1.71-1.98
Engine  Stall speed RPM 
B5204T5 2800

Normal stall speed at sea level and an air temperature of +20 °C (the engine speed (RPM) reduces by 120 RPM per 1000 meters above sea level and by 50-100 RPM per 10°C above +20°C air temperature).

Repeat the test with gear selector in position R.

Compare to the table.

If the engine speed (RPM) exceeds the value in the table, see High stalling speed  . If the engine speed (RPM) is less than the value in the table, see Low stalling speed  .
