2.ACTIVE TEST
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.
d. Turn the ignition switch to the ON position.
e. Push the "ON" button of the hand-held tester.
f. Select the item "DIAGNOSIS/ENHANCED OBD II/ACTIVE TEST".
g. According to the display on tester, perform the "ACTIVE TEST".

According to the DATA LIST displayed by the hand-held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
method to shorten labor time.
a. Turn the ignition switch off.
b. Connect the hand-held tester together with the CAN VIM (controller area network vehicle interface
module) to the DLC3.
c. Turn the ignition switch to the ON position.
d. Push the "ON" button of the OBD II scan tool or the hand-held tester.
e. Select the item "DIAGNOSIS/ENHANCED OBD II/DATA LIST".
f. According to the display on tester, read the "DATA LIST".

DTC P0713 is output and hand-held tester output is -40°C (-40°F), there is an open circuit. Measure the
resistance between terminal OIL (OT) and body ground.
CHECKING CIRCUIT MALFUNCTION TABLE
HINT:
If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately set (in 0.5 second).
When P0713 is set, P0711 cannot be detected.
