Check Mode Procedure

  1. CHECK MODE (SIGNAL CHECK): DTC CHECK 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Select "SIGNAL CHECK", and proceed with checking using the tester.
      NOTE:

      Select "SIGNAL CHECK" from the "DTC CHECK" screen displayed on the tester to clear the output DTCs (both present and past).

      HINT: 

      • DTCs can be detected more sensitively in check mode than in normal diagnosis mode.
      • Perform the check mode inspection when a malfunction in each squib circuit is suspected even after the normal system code is output through the normal diagnosis mode inspection.
