Scantool Diagnostics

Automatic Transaxle
P0732 Gear 2 Incorrect Ratio - Scantool Diagnostics

Monitor GDS Data

Stall Test
1. Connect GDS to data link connector(DLC).
2. Engine "ON".
3. Monitor the "ENGINE SPEED, INPUT SPEED SENSOR, OUTPUT SPEED SENSOR, GEAR POSITION" parameter on the GDS.
4. Perform the "STALL TEST" with gear position "2".

Specification :2300 ± 200 engine rpm




OPERATING ELEMENT OF EACH SHIFTING RANGE





X : WORKING.
◆ : PARTICIPATE IN DELIVERY TORQUE WHEN COAST DRIVING.
O : SUPPLING OIL PRESSURE TO ELEMENT, BUT NOT EFFECT ON OUTPUT.
�. : TEMPORARY WORKING.

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?






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 °F - 212 °F (80 - 100 °C).
- Engine coolant temperature : 176 °F - 212 °F (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 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.

Signal Check
1. Connect GDS.
2. Engine "ON".
3. Monitor the "INPUT & OUTPUT SPEED SENSOR" parameter on the GDS.
4. Accelerate the Engine speed until about 2000 rpm in the 2nd gear.

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




5. Does "INPUT & OUTPUT SPEED SENSOR" within specifications?
