Inspection Procedure

  1. CHECK FOR DTC 
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG) and turn the Techstream ON.
    3. By following the Techstream screen display, check whether any DTCs are output.

    OK: No DTC output.

    A: Go to next step 

  2. CHECK MANUAL DOOR LOCK AND UNLOCK OPERATION 
    1. Check that all the doors lock when the door control switch (for manual operation) is turned to LOCK and UNLOCK.

    OK: All doors can be locked and unlocked with door control switch. 

    NG: Go to POWER DOOR LOCK CONTROL SYSTEM  (See OPERATION CHECK )

    OK: Go to next step 

  3. PERFORM ACTIVE TEST USING TECHSTREAM (DOOR ELECTRICAL KEY OSCILLATOR) 
    1. Select the Active Test, use the Techstream to generate a control command, and then check that the oscillator operates.
