Stall Test
- Perform the mechanical system test preparation. (See MECHANICAL SYSTEM TEST .)
- Apply the parking brake firmly, and set the wheel blocks for both the front and rear wheels.
- Start the engine.
- Measure the stall speed in the D position.
- Strongly depress the brake pedal with the left foot.
- Shift the selector lever to the D position.
CAUTION:
- To prevent damage to the transaxle, measure the stall speed (Step (3)-(4)) within 5 s.
- Slowly depress the accelerator pedal fully with the right foot all the way down.
- Read the engine speed quickly when the speed is stabilized, and remove the right foot from the accelerator pedal.
- Shift the selector lever to the N position and idle for 1 min or more.
- Measure the stall speed in the M (1st gear) and R positions using the same procedure.
- If there is any malfunction, one of the following causes may have occurred:
| Condition |
Possible cause |
| Higher than specification |
Higher in R, D, and M (1GR) position |
Line pressure is low |
- Oil pump wear
- ATF leakage from oil pump, control valve body, and transaxle case
- Pressure regulator valve sticking
- TR control valve sticking
- Pressure control solenoid operation malfunction
|
- Low and reverse brake slippage, and damage of one - way clutch
|
| Higher in D and M (1GR) position |
- Low clutch slippage
- One-way clutch damage
|
| Higher in R position |
Perform road test to determine whether problem is in R-3-5 brake or low and reverse brake
- Engine brake operates in M (1GR) position
- Engine braking does not operate in M (1GR) position
- Low and reverse brake slippage
|
| Lower than specification |
Lower in R, D, and M (1GR) position |
- Engine malfunction
- One-way clutch slippage in torque converter
