Monitor Scantool Data

Monitor Scantool Data

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









CAUTION:
Stall test procedure in D2 and reason
Procedure
1. Warm up the engine
2. After positioning the select lever in "D" or "ON" of the HOLD SW (Operate UP SHIFT in case of "SPORTS MODE"),depress the foot brake pedal fully after that, depress the accelerator pedal to the maximum
* The slippage of 2ND BRAKE can be detected by stall test in D2
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 2nd brake system (2nd gear operating part) has faults, input speed revolution will be out.
4. If output speed revolution is output. It means that the foot brake force is not applied fully. Remeasuring is required.

5. 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 : 80-100 °C.
Engine coolant temperature : 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 seconds.
6. 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.
