DTC
CODE
DTC DETECTION CONDITION
TROUBLE AREA
Automatic transmission
(clutch, brake, gear,
etc.)
P2714
The ECM detects a malfunction in shift solenoid valve SLT (ON
Shift solenoid valve SLT
remains open or closed
Shift solenoid valve S1,
S2, S3, S4 or SL2
remains open or closed
Gear 6 incorrect ratio
(sequence valve) or 1-2
shift valve is stuck
Valve body is blocked
Automatic transmission
(clutch, brake, gear,
etc.)
MONITOR DESCRIPTION
When the shift solenoid valve SLT remains ON, oil pressure decreases, which causes the clutch
engagement force to decrease.
When a shift solenoid valve remains ON or OFF, the gear position commanded by the ECM and the
actual gear position are not the same.
NOTICE:
If you continue driving under these conditions, the clutch will burn out and the vehicle will no longer be
drivable.

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.
A760F AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISS...
A
OK
(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.
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.
B
GO TO DTC CHART
2.
PERFORM ACTIVE TEST USING TECHSTREAM (SHIFT SOLENOID VALVE SLT)
NG
GO TO STEP 17
3.
PERFORM ACTIVE TEST USING TECHSTREAM (RUNNING TEST)
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) Connect the Techstream to the DLC3.
(b) Clear the DTC
.
(c) Enter the following menus: Powertrain / Engine and ECT / Active Test.
