Monitor SCANTOOL 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.
- Perform the " STALL TEST " with gear position "1"
Specification: 2100~2800 engine RPM

Stall test procedure in D1 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 D
Reason for stall test
- If there is no mechanical defaults in A/T, all slippage occurs in torque converter.
- Therefore, engine revolution is output, but input and output speed revolution must be "zero".
- If 1st gear operating part has faults, input speed revolution will be out.
- If output speed revolution is output. It means that the foot brake force is not applied fully. Remeasuring is required.
- 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: 176 °F~ 212 °F (80~100 °C).
- Engine coolant temperature: 176 °F~ 212 °F (80~100 °C).
- 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 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.
