Data List / Active Test

HINT:

Using the Techstream 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.

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Read the DATA LIST according to the display on the tester.

   HINT:

   • "3" is OK but '1" is NG → ECM failure
   • "1" is OK but failure "2" is NG → DTC output or ECM
   • "3" is OK but CRUISE main indicator light does not illuminate → CRUISE main indicator light, wire harness or ECM failure

HINT:

Performing the Techstream 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. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Perform the ACTIVE TEST according to the display on the tester.

   HINT:

   The engine switch must be turned to ON (IG) to proceed to ACTIVE TEST using the Techstream.
