Monitor SCANTOOL Data
- Connect scantool to data link connector (DLC).
- Engine "ON".
- Monitor the "ENGINE SPEED, INPUT SPEED SENSOR, OUTPUT SPEED SENSOR, GEAR POSITION" parameter on the scantool.
- Perform the "STALL TEST" with gear position "2".
Specification : 2000~2700 engine rpm
* This test is possible only for "HOLD S/W" or "SPORTS MODE" applied vehicles.

Stall test procedure in D2 and reason
Procedure
- Warm up the engine
- After positioning the select lever in "D", depress the foot brake pedal fully after that, depress the accelerator pedal to the maximum
* The slippage of 1st gear operating parts can be detected by stall test in D2.
Reason for stall test
- If there are mechanical defaults in A/T, all slippage occurs in the torque converter.
- Therefore, engine revolution is output, but input and output speed revolution must be "zero" due to wheel's lock.
- If 2nd brake system (2nd gear operating part) has faults, input speed revolution will be out of specification.
- If wheel spin occurs, the applied brake force is not adequate. Retry using more brake force.
- Is "STALL TEST" within specification?
YES
- Go to "SIGNAL CIRCUIT 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 °F~ 212 °F).
- Engine coolant temperature : 80~100 °C (176 °F~ 212 °F).
- Chock both rear wheels (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 seconds.
- 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 tests.
