1.

Start the engine and warming up properly

2.

After connecting Scantool and monitor the "ENGINE SPEED, INPUT SPEED SENSOR, OUTPUT SPEED SENSOR, GEAR POSITION "parameter on the Scantool data list.

3.

Do stall test of the D1 range

note

Stall test procedure in D1 and reason

1)

Procedure

a.

1. Warm up the engine

b.

2. After positioning the select lever in "D", step on the foot brake fully after that, step on the accelator to the maximum

* Tthe slippage of one way clutch and UD clutch can be detected by stall test in D1

2)

Reason for stall test

a.

1.If there is no mechanical defaults in A/T, every slippage occur in torque converter.

b.

2. Therfore, engine revolution is out, but input and output speed revolution must be "zero" due to wheel’s lock.

c.

3. If UD clutch system or one way clutch (1st gear operating part) has faults, input speed revolution will be out.

d.

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

4.

Is display data near the specified value?

YES

a.

Check output speed sensor measuring value is abnormal(confirm noise and signal error)

b.

After erasing the code memory, confirm reoccuring of trouble code

NO

a.

In case of input speed sensor detecting revolution

- Repair(Replace A/T ass’y) one way clutch, UD clutch defect or oil ressure system defect and go to "Verification of Vehicle Repair" procedure.

b.

In case of output speed sensor detecting revolution

- It means that the foot brake is not applied fully . Remeasuring is required.
