note

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 gear operating parts 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. Therfore, engine revolution is output, but input and output speed revolution must be "zero" due to wheel's lock.

3. If 2nd gear operating parts have faults, input speed revolution will be out.

4. If oupput speed revolution is output. It means that the foot brake force is not applied fully. Remeasuring is required.

5.

Is the meausred "STALL TEST " within specifications?

	▶ Go to "signal check" as follow
	▶ 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 ℉ (80~100 ℃).

•

Engine coolant temperature : 176 ℉~ 212 ℉ (80~100 ℃).

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 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.

6.

Connect Scantool.

7.

Engine "ON" .

8.

Monitor the "INPUT & OUTPUT SPEED SENSOR" parameter on the scantool.

9.

Accelerate the Engine speed until about 2000 rpm in the 2nd gear.

Specification : INPUT SPEED - (OUTPUT SPEED × 2nd GEAR RATIO) ≤ 200 RPM

10.

Does "INPUT & OUTPUT SPEED SENSOR" within specifications?

	▶ Go to "Component Inspection" procedure.
	▶ Check for electrical niose of circuit in INPUT & OUTPUT SPEED SENSOR or Replace INPUT & OUTPUT SPEED SENSOR. Repair as necessary and Go to "verification of vehicle repair" procedure.
