Monitor Scan Tool Data

Connect scan tool to data link connector (DLC)
Engine "ON".
Monitor the "ENGINE SPEED, INPUT SPEED SENSOR (PG-A), OUTPUT SPEED SENSOR (PG-B), GEAR POSITION" parameter on the scan tool

Perform the "STALL TEST" with gear position "R"

NOTE:
Stall test procedure in D3 and reason
Procedure
1. Warm up the engine
2. After making 3rd gear holding by disconnecting the solenoid valve connector, and Then depress the foot brake pedal fully After that, step on the accelerator pedal to the maximum
* The slippage of 3rd gear operating parts can be detected by stall test in D3.
Reason for stall test
1. If there is no mechanical defaults in A/T, every slippage occur in torque converter.
2. Therefore, engine revolution is output, but input and output speed revolution must be "zero" due to wheel's lock.
3. If 3rd gear operating parts has faults, input speed revolution will be output.
4. If output speed revolution is output. It means that the foot brake force is not applied fully. Re-measuring is required.

Is "STALL TEST" within specifications?
YES
1. Go to "W/HARNESS INSPECTION " procedure
NO
1. Go to "COMPONENT INSPECTION " procedure
  CAUTION:
  1. Do not let anybody stand in front of or behind the vehicle while this test is being carried out.
  2. Check the A/T fluid level and temperature and the engine coolant temperature.
    
    Fluid level : At the hot mark on the oil level gauge.
    
    Fluid temperature : 176 ~ 212 °F (80 ~ 100 °C).
    
    Engine coolant temperature : 176 ~ 212 °F (80 ~ 100 °C).
  3. Chock both rear wheel (left and right).
  4. Pull the parking brake lever on with the brake pedal fully depressed.
  5. The throttle should not be left fully open for more than eight second.
  6. If carrying out the stall test two or more times, move the select lever to the "N" position and run the engine at 1, 000 RPM to let the A/T fluid cool down before carrying out subsequent testing.
* Perform stall test on "L" range If the result of stall test on "D" range is out of specifications. "One Way Clutch" is faulty If the result of stall test on "L" range is within specifications.
