Monitor Scan Tool Data
- Connect scan tool to data link connector (DLC).
- Engine "ON".
- Monitor the "ENGINE SPEED, INPUT SPEED SENSOR, OUTPUT SPEED SENSOR, GEAR POSITION" parameter on the scan tool.
- Disconnect the solenoid valve connector and perform the "STALL TEST".
Specification : ~ 2700 engine RPM

NOTE: Stall test procedure in D3 and reason
Procedure- Warm up the engine
- After making 3rd gear hold by disconnecting the solenoid 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- If there is no mechanical defaults in A/T, every slippage occur in torque converter.
- Therefore, engine revolution is output, but input and output speed revolution must be "zero" due to wheel's lock.
- If OD clutch system (3rd gear operating part) has faults, input speed revolution will be output.
- If output speed revolution is output. It means that the foot brake force is not applied fully. Remeasuring is required.
- Is "STALL TEST" within specifications?
YES
- Go to "W/HARNESS INSPECTION " procedure.
NO
- Go to "COMPONENT INSPECTION " procedure.CAUTION:
- Do not let anybody stand in front of or behind the vehicle while this test is being carried out.
- 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 : 80~100 °C (176~212°F).
- Engine coolant temperature : 80 ~ 100 °C (176~212°F).
- Chock both rear wheel (left and right).
- Pull the parking brake lever on with the brake pedal fully depressed.
- The throttle should not be left fully open for more than eight second.
- If carrying out the stall test two or more time, 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.
