Check Mode Procedure

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 Techstream 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.
