PROCEDURE
1. REPLACE ECM
(a) Replace the ECM See: Powertrain Management/Computers and Control Systems/Engine Control Module/Service and
Repair/Removal.
NEXT -- Continue to next step.
2. CHECK WHETHER DTC OUTPUT RECURS
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Clear the DTCs See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Reading and Clearing
Diagnostic Trouble Codes/DTC Check / Clear.
(e) Start the engine and wait for 10 minutes or more.
(f) Enter the following menus: Powertrain / Engine / Trouble Codes / Pending.
(g) If no pending DTC is displayed, the repair has been successfully completed.

U660E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P2714: Pressure Control Solenoid "D"
Performance (Shift Solenoid Valve SLT)
P2714 - Pressure Control Solenoid "D" Performance (Shift Solenoid Valve SLT)
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 TCM 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 electrical current on time (A) to the total of the electrical current on and off time (A + B).
Duty Ratio (%) = (A / (A + B)) x 100
