INSPECTION PROCEDURE
NOTICE:
Perform the universal trip to clear permanent DTCs
.
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.
AB60F AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMIS...
A
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(e) Read the DTCs using the Techstream.
Result
RESULT
PROCEED TO
Only P0894 is output
Only P0894 and P2714 are output
A
P0894, P2714 and other DTCs are output
B
HINT:
If any other codes besides P0894 and P2714 are output, perform troubleshooting for those DTCs first.

2.
PERFORM ACTIVE TEST USING TECHSTREAM (SHIFT SOLENOID VALVE SLT)
NOTICE:
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.
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.
AB60F AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMIS...
(a) Remove the test plug on the transmission case center right
side and connect SST.
SST: 09992-00095
09992-00231
09992-00271
(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.

DIAGNOSTIC NOTE
Activate the
Solenoid
(SLT)*
Operate shift
solenoid SLT and
raise line pressure
ON or OFF
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)
[Vehicle Condition]
Vehicle
stopped
Engine
idling
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 the Hydraulic Test
as well. Note that
the pressure values in the Active Test and Hydraulic Test are different.
