SYSTEM DESCRIPTION
The linear solenoid valve (SLT) controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and the vehicle speed sensor. The ECM adjusts the duty ratio (*) of the SLT solenoid valve to control hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.
(*): Duty Ratio The duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity in one cycle, and B is the period of non-continuity, then Duty Ratio=A/(A+B) x 100(%)
MONITOR DESCRIPTION
In any forward position, when the difference between the revolutions of the turbine, Intermediate and output shaft exceeds the specified value (varies with Intermediate, output speed) determined by the ECM, the ECM illuminates the MIL and store the DTC.
When shift solenoid valve SLT remains on, the oil pressure goes down and the clutch engagement force decreases.
NOTICE: If you continue driving under these conditions, the clutch will burn out and the vehicle will no longer be drivable. |
MONITOR STRATEGY
TYPICAL ENABLING CONDITIONS
TYPICAL MALFUNCTION THRESHOLDS
[ON malfunction] Detection condition: Total accumulated time of ON malfunctions (a), (b), (c), (d) and (e) is 0.5 second or more
INSPECTION PROCEDURE
1 CHECK OTHER DTCS OUT PUT (IN ADDITION TO DTC P2714)
(a) Connect the OBD II scan tool or intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
(b) Turn the ignition switch to the ON position and turn the OBD II scan tool or the intelligent tester main switch ON.
(c) When you use intelligent tester: Select the item "DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES" (d) Read the DTCs using the OBD II scan tool or the intelligent tester.
Result
HINT: If any other codes besides "P2714" are output, perform the troubleshooting for those DTCs first.
2 INSPECT SHIFT SOLENOID VALVE SLT
(a) Remove the shift solenoid valve SLT.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
(c) 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 an operating sound.
3 INSPECT TRANSMISSION VALVE BODY ASSEMBLY
OK: There are no foreign objects on each valve.
4 INSPECT TORQUE CONVERTER CLUTCH ASSEMBLY
OK: The torque converter clutch operates normally.

Disposal
1. DISPOSE OF SHOCK ABSORBER ASSEMBLY REAR LH
(a) Fully extend the shock absorber rod.
(b) Using a drill, make a hole in the cylinder as shown in
the illustration to discharge the gas inside the
cylinder.
CAUTION:
When drilling, since the fragments may fly
out, work careful ...
For manual air conditioning system
ON-VEHICLE INSPECTION
1. INSPECT AIR INLET CONTROL SERVO MOTOR
(a) Remove the air inlet control servo motor.
(b) Connect the positive (+) lead from the battery to
terminal 5 and negative (-) lead to terminal 1, then
check that the lever turns to "RECIRCULATION"
side smoothly.
