1. Warm up the engine.  

2. After making 3rd gear hold by disconnecting the solenoid connector, and Then depress the foot 

brake pedal fully After that, step on the accelerator pedal to the maximum. 

* The slippage of 3rd gear operating parts can be detected by stall test in D3. 

Reason for stall test 

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

2. Therefore, engine revolution is output, but input and output speed revolution must be "zero" due to 

wheel's lock.  

3. If OD clutch system (3rd gear operating part) has faults, input speed revolution will be out of 

specification.  

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

Remeasuring is required.  

5. Is "STALL TEST" within specification? 

YES  



Go to "SIGNAL CIRCUIT INSPECTION" procedure. 

NO  



Go to "COMPONENT INSPECTION" procedure.  

SIGNAL CIRCUIT INSPECTION 

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°F (80-100°C).  



Engine coolant temperature: 176-212°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 stall test Is being performed more than once, move the 

selector lever to N and run the engine at 1000 RPM to allow the 
transaxle fluid to cool prior to subsequent tests.

1. Connect scan tool.  

2. Engine "ON".  

3. Monitor the "INPUT & OUTPUT SPEED SENSOR" parameter on the scan tool.  

4. Accelerate the Engine speed until about 2000 RPM in the 3rd gear. 

Specification: INPUT SPEED - (OUTPUT SPEED x GEAR RATIO) < or = 200 RPM

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

YES  



Go to "COMPONENT INSPECTION" procedure.  

NO  



Check for electrical noise of circuit in INPUT & OUTPUT SPEED SENSOR or Replace INPUT & 
OUTPUT SPEED SENSOR. Repair as necessary and Go to "VERIFICATION OF VEHICLE 
REPAIR" procedure.

1. Connect oil pressure gauge to "UD" and "OD" and "RED" port.  

2. Engine "ON".  

3. Drive a car with gear position 3 in "SPORTS MODE".  

4. Compare it with reference data. 

Specification: refer to DTC P0731. 

5. Is oil pressure value within specifications? 

YES  



Repair AUTO TRANSAXLE (Clutch or Brake) as necessary and Go to "VERIFICATION OF 
VEHICLE REPAIR" procedure.  

NO  



Replace AUTO TRANSAXLE (BODY CONTROL VALVE faulty) as necessary and Go to 
"VERIFICATION OF VEHICLE REPAIR" procedure.
