HINT:
If any other codes besides "P2714" are output, perform troubleshooting for those DTCs first.
B: GO TO RELEVANT DTC CHART (See DIAGNOSTIC TROUBLE CODE CHART
)

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:
SHIFT SOLENOID VALVE (SLT) - RESISTANCE TABLE
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 noise.

HINT:
This test can be conducted when the vehicle speed is 58 km/h (36 mph) or more.
This test can be conducted with the 5th or 6th gear.
i. Lightly depress the accelerator pedal and check that the engine speed does not change abruptly.
HINT:
When changing the accelerator pedal opening angle while driving, if the engine speed does not change,
lock-up is on.
Slowly release, but not fully, the accelerator pedal in order to decelerate. (Fully releasing the pedal will
close the throttle valve and loc
k-up may be turned off automatically.)

OK: Go to next step
4.CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)
a. Connect the transmission control switch connector of shift lock control unit assy.
b. Turn the ignition switch to the ON position, and measure the voltage according to the value(s) in
the table below when the shift lever is moved to each position.

d. Disconnect the ECM connector.

ON-VEHICLE INSPECTION
1.INSPECTION THROTTLE BODY
a. Inspect the throttle control motor for operating sound.
1. Turn the ignition switch ON.
2. When turning the accelerator pedal position sensor lever, check the running sound of the
motor. The motor should be running smoothly without friction sounds.
If operation is not as specified, check the throttle control motor, wiring and ECM (see DTC P2118:
THROTTLE ACTUATOR CONTROL MOTOR CURRENT RANGE/PERFORMANCE ).
