INSPECTION PROCEDURE

1. CHECK DTC OUTPUT (IN ADDITION TO DTCS P0894 AND P2714)

a. Connect the Techstream to the DLC3.

b. Turn the ignition switch to ON.

c. Turn the Techstream on.

d. Enter the following menus: Powertrain/Engine and ECT/Trouble Codes.

e. Read the DTCs using the Techstream.

HINT:

If any other codes besides P0894 and P2714 are output, perform troubleshooting for those DTCs
first.

B: GO TO DTC TABLE (See DIAGNOSTIC TROUBLE CODE TABLE )

A: Go to next step.

2. PERFORM ACTIVE TEST USING TECHSTREAM (SHIFT SOLENOID VALVE SLT)

HINT:

Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be
operated without removing any parts. This non-intrusive functional inspection can be very useful because
intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests
early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while
performing Active Tests.

a. Remove the test plug on the transmission case center right side and connect SST.

SST 09992-00095 (09992-00231, 09992-00271)

Result

Proceed to



Only P0894 is output



Only P0894 and P2714 are output

A

P0894, P2714 and other DTCs are output

B

NOTE:



Perform the test at the normal operating ATF temperature: 50 to 80°C
(122 to 176°F).



Be careful to prevent SST's hose from interfering with the exhaust
pipe.



Perform the test with the A/C OFF.

b. Connect the Techstream to the DLC3.

c. Start the engine and warm it up.

d. Measure the line pressure with SST.

e. Turn the Techstream on.

f. Enter the following menus: Powertrain/Engine and ECT/Active Test.

g. According to the display on the Techstream, perform the Active Test.

h. Measure the line pressure.

3. PERFORM ACTIVE TEST USING TECHSTREAM (RUNNING TEST)

a. Connect the Techstream to the DLC3.

b. Clear the DTC (see DTC CHECK/CLEAR ).

c. Warm up the engine.

d. Enter the following menus: Powertrain/Engine and ECT/Active Test.

e. According to the display on the Techstream, perform the Active Test.

HINT:

While driving, the shift position can be forcibly changed with the Techstream.

Engine and ECT:

ACTIVE TEST TABLE

HINT:

*: Activate the Solenoid (SLT) in the Active Test is performed to check the line pressure changes
by connecting SST to the automatic transmission, which is used in HYDRAULIC TEST as well.
Note that the pressure values in the Active Test and Hydraulic Test are different.

CAUTION: This test should always be performed with at least 2 people.

NOTE:



Perform the test at the normal operating ATF temperature: 50 to 80°C
(122 to 176°F).



Perform the test with the A/C turned off.
