Inspection Procedure

HINT:

Performing Techstream's Active Test allows relay, VSV, actuator and other items to be operated without removing any parts. Performing the Active Test early in troubleshooting is one way to save time.

The Data List can be displayed during the Active Test.

1. Warm up the engine.
2. Turn the ignition switch OFF.
3. Connect Techstream to the DLC3.
4. Turn the ignition switch ON and turn the tester ON.
5. Enter the following menus: Powertrain / Engine and ECT / Active Test.
6. Perform the Active Test.
   TESTER DISPLAY - CONTROL RANGE AND DIAGNOSTIC NOTE
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Activate the Solenoid (SLT)*	[Test Details] Operate shift solenoid SLT and raise line pressure [Vehicle Condition] Vehicle stopped IDL: ON HINT: OFF: Line pressure up (when Active Test "Activate the Solenoid (SLT)" is performed, ECM commands SLT solenoid to turn OFF) ON: No action (normal operation)	ON/OFF	-
   HINT: *: "Activate the Solenoid (SLT)" in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transaxle, which is used in the HYDRAULIC TEST (see HYDRAULIC TEST  ) as well. Please note that the pressure values in the Active Test and HYDRAULIC TEST are different.

1. CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P2714) 
   1. Connect Techstream to the DLC3.
   2. Turn the ignition switch ON and turn the tester ON.
   3. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
   4. Read the DTCs using the tester.

      Result 

      DTC RESULT DESCRIPTION
      
      

      Display (DTC output)	Proceed to
      Only P2714 is output	A
      P2714 and other DTCs are output	B

      HINT:

      If any other codes besides P2714 are output, perform troubleshooting for those DTCs first.

   B: GO TO DTC CHART 

   A: Go to Next Step 

2. INSPECT SHIFT SOLENOID VALVE SLT 
   1. Remove the shift solenoid valve SLT.

   2. Measure the resistance of the solenoid valve.

      Standard resistance: 

      5.0 to 5.6 Ω at 20°C (68°F) 

   3. Connect the battery's positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating noise.

      OK: Valve moves and makes operating noise. 

   NG: REPLACE SHIFT SOLENOID VALVE SLT 

   OK: Go to Next Step 

3. INSPECT TRANSMISSION VALVE BODY ASSEMBLY 
   1. Check the transmission valve body assembly.

      OK: There are no foreign objects on each valve. 

   NG: REPAIR OR REPLACE TRANSMISSION VALVE BODY ASSEMBLY 

   OK: Go to Next Step 

4. INSPECT TORQUE CONVERTER CLUTCH ASSEMBLY 
   1. Check the torque converter clutch assembly (See TORQUE CONVERTER AND DRIVE PLATE  ).

      OK: The torque converter clutch operates normally. 

   NG: REPLACE TORQUE CONVERTER CLUTCH ASSEMBLY 

   OK: REPAIR OR REPLACE AUTOMATIC TRANSAXLE ASSEMBLY
