Stall test procedure in D3
Compare with under the data
Stall test procedure and reason in D2
Procedure
1. Warm up Engine
2. Disconnect Solenoid connector, make FAIL state with D3 HOLD. depress the foot brake fully and the accelator
* the slippage of one way clutch can be detected by stall test in D3
Reason
1.If there is no mechanical defaults in A/T, every slippage occur in torque converter.
2 Therfore, engine revolution is out, but input and output speed revolution must be “zero” due to wheel’s lock
3. If OD clutch system(3rd gear operating part) have faults, input speed revolution will be out.
4. If output speed revolution is out. It means that the foot brake is not applied fully. Try again.
<Scantool normal data>
Is input speed displayed near the specified value?
YES
Check that output sensor’s measured value is not normal. PG-A(IN),PG-B(OUT) (refer to DTC list P0717 PG-A,P0722 PG-B)
After erasing the code memory, confirm trouble code again.
NO
In case of detecting revolution of input speed sensor.
- UD and OD clutch are faulty or oil pressure system defect(replace the A/T ASS’Y)
- Repair, verify Verification Veh. Repair
In case of detecting revolution of output speed sensor
- Brake operate illegaliy or Tire revolution , the foot Brake depress fully. Try again.
