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 D3 range

note

Stall test procedure in D3 and reason

1)

Procedure

a.

1. Warm up the engine

b.

2. After making 3rd gear hold by disconnecting the solenoid connector, Second, step on the foot brake fully After that, step on the accelator to the maximum

* The slippage of OD clutch can be detected by stall test in D3.

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 OD clutch system(3rd 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 the A/T ass’y) UD clutch, OD clutch(3rd stall value abnormal) defect or oil pressure system defect

b.

In case of output speed sensor detecting revolution

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