Inspection Procedure

HINT:

Performing the Active Test using the Techstream allows components, such as the relay, VSV, and actuator, to be operated without removing any parts. Performing the Active Test as the first step of troubleshooting is one method of shortening labor time.

It is possible to display the Data List during the Active Test.

1. Warm up the engine.
2. Turn the ignition switch off.
3. Connect the Techstream to the DLC3.
4. Turn the ignition switch to ON.
5. Turn the tester on.
6. Select the following items: Powertrain / Engine and ECT / Active Test.
7. In accordance with the display on the tester, perform the Active Test.

   Tester Display	Test Part	Control Range	Diagnostic Note
   Activate the Solenoid (SLT)(1)	[Test Details] Operate shift solenoid SLT and raise line pressure. [Vehicle Condition] Vehicle Stopped Engine idling HINT: OFF: Line pressure up (when active test of SOLENOID (SLT) is performed, ECM turns off SLT solenoid) ON: No action (normal operation)	ON/OFF	-
   (1) 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.

   HINT:

   The pressure values in Active Test and HYDRAULIC TEST are different from each other.

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the tester on.
4. Select the following items: Powertrain / Engine and ECT / Trouble Codes.
5. Read the DTCs using the tester.

   P2714 and other DTCs	B

   HINT:

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

B: GO TO DTC CHART 

A: go to next step 

1. Remove shift solenoid valve SLT.

2. Measure the resistance.

   Standard resistance 

   STANDARD RESISTANCE SPECIFICATION
   
   

   Tester Connection	Specified Condition
   1 - 2	5.0 to 5.6 Ω at 20°C (68°F)

3. Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

   OK: 

   The solenoid makes operating sounds. 

NG: REPLACE SHIFT SOLENOID VALVE SLT (See  DISASSEMBLY   ) 

OK: go to next step 

OK: 

There are no foreign objects on any valves and they operate smoothly. 

NG: REPAIR OR REPLACE TRANSMISSION VALVE BODY ASSEMBLY (See  REMOVAL   ) 

OK: go to next step 

OK: 

The torque converter clutch operates normally. 

NG: REPLACE TORQUE CONVERTER CLUTCH ASSEMBLY (See  REMOVAL   ) 

OK: REPAIR OR REPLACE AUTOMATIC TRANSAXLE ASSEMBLY (See  REMOVAL   )
