   Only P0781 is output	A
   P0781 and other DTCs	B

   HINT:

   If any other codes besides P0781 are output, perform troubleshooting for those DTCs first.

HINT:

Performing the intelligent tester's ACTIVE TEST allows relay, VSV, actuator and other items to be operated without removing any parts. Performing the ACTIVE TEST early in troubleshooting is one way to save time.

The DATA LIST can be displayed during the ACTIVE TEST.

1. Warm up the engine.
2. Turn the ignition switch OFF.
3. Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
4. Turn the ignition switch ON.
5. Turn the intelligent tester ON.
6. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST.
7. Read the ACTIVE TEST using the intelligent tester.

   HINT:

   While driving, the shift position can be forcibly changed with the intelligent tester.

   Comparing the shift position commanded by the ACTIVE TEST with the actual shift position enables you to confirm the problem (see DTC P0711 TRANSMISSION FLUID TEMPERATURE SENSOR "A" PERFORMANCE  ).
