INSPECTION PROCEDURE
HINT:
Performing the ACTIVE TEST using the hand-held tester allows the relay, VSV, actuator and so on to operate
without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one method to
shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
a. Warm up the engine.
b. Turn the ignition switch off.
c. Connect the hand-held tester together with the CAN VIM (controller area network vehicle interface
module) to the DLC3.
Turbine speed/Output speed (NT/NO)1.23 or more and 1.48 or less (This means actual
gear is 3rd)
Turbine speed/Output speed (NT/NO)0.66 or more and 0.80 or less (This means actual
gear is 5th
Turbine speed/Output speed (NT/NO)0.50 or more and 0.64 or less (This means actual
gear is 6th)
Turbine speed/Output speed (NT/NO)0.50 or more and 0.64 or less (This means actual
gear is 6th)

d. Turn the ignition switch to the ON position.
e. Push the "ON" button of the hand-held tester.
f. Clear the DTC.
g. Select the item "DIAGNOSIS/ENHANCED OBD II/ACTIVE TEST/SHIFT".
h. According to the display on tester, perform the "ACTIVE TEST".
HINT:
While driving, the shift position can be forcibly changed with the hand-held tester.
Comparing the shift position commanded by the ACTIVE TEST with the actual shift position enables you to
confirm the problem (see FAIL
-SAFE CHART).

HINT:
The pressure values in ACTIVE TEST and HYDRAULIC TEST are different from each other.
Normally, the line pressure detected in the ACTIVE TEST is approximately half of the value detected in
the HYDRAULIC TEST's stall test.
1.CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P2714)
a. Connect the han
d-held tester to the DLC3.

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 ).

b. Inspect the throttle position sensor.

1.DATA LIST
HINT:
Using the hand-held tester's DATA LIST allows switch, sensor, actuator and other item values to be read
without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.
a. Connect the hand-held tester to the Controller Area Network Vehicle Interface Module (CAN
VIM). Then connect the CAN VIM to the DLC3.
b. Turn the ignition switch ON.
c. Read the DATA LIST.
